First add an Enrty and Category class:

public class Entry {     public string Id { get; set; }     public string Title { get; set; }     public string Updated { get; set; }     public string Summary { get; set; }     public string GPoint { get; set; }     public string GElev { get; set; }     public List<string> Categories { get; set; } }  public class Category {     public string Label { get; set; }     public string Term { get; set; } } 

Then use LINQ to XML

XDocument xDoc = XDocument.Load("path");          List<Entry> entries = (from x in xDoc.Descendants("entry")             select new Entry()             {                 Id = (string) x.Element("id"),                 Title = (string)x.Element("title"),                 Updated = (string)x.Element("updated"),                 Summary = (string)x.Element("summary"),                 GPoint = (string)x.Element("georss:point"),                 GElev = (string)x.Element("georss:elev"),                 Categories = (from c in x.Elements("category")                                   select new Category                                   {                                       Label = (string)c.Attribute("label"),                                       Term = (string)c.Attribute("term")                                   }).ToList();             }).ToList(); 

Perhaps a little off topic, just be informed that these kind of messages can also be seen when you are debugging your code with a breakpoint inside an async function like setTimeout like below:

[Violation] 'setTimeout' handler took 43129ms

That number (43129ms) depends on how long you stop in your async function

You can do something similar to this:

// Get the parent to attatch the element into
var parent = document.getElementsByTagName("ul")[0];

// Create element with random id
var element = document.createElement("li");
element.id = "li-"+Math.floor(Math.random()*9999);

// Add event listener
element.addEventListener("click", EVENT_FN);

// Add to parent
parent.appendChild(element);

Follow this method if problem comes when working with angular2+ projects

I was looking for a solution when i got this error, and it got me here. But this question seems to be specific but the error is not, its a generic error. This is a common error for angular developers dealing with Internet Explorer.

I had the same issue while working with angular 2+, and it got resolved just by few simple steps.

In Angular latest versions, there are come commented codes in the polyfills.ts shows all the polyfills required for the smooth running in Internet Explorer versions IE09,IE10 and IE11

/** IE9, IE10 and IE11 requires all of the following polyfills. **/
//import 'core-js/es6/symbol';
//import 'core-js/es6/object';
//import 'core-js/es6/function';
//import 'core-js/es6/parse-int';
//import 'core-js/es6/parse-float';
//import 'core-js/es6/number';
//import 'core-js/es6/math';
//import 'core-js/es6/string';
//import 'core-js/es6/date';
//import 'core-js/es6/array';
//import 'core-js/es6/regexp';
//import 'core-js/es6/map';
//import 'core-js/es6/weak-map';
//import 'core-js/es6/set';

Uncomment the codes and it would work perfectly in IE browsers

/** IE9, IE10 and IE11 requires all of the following polyfills. **/
import 'core-js/es6/symbol';
import 'core-js/es6/object';
import 'core-js/es6/function';
import 'core-js/es6/parse-int';
import 'core-js/es6/parse-float';
import 'core-js/es6/number';
import 'core-js/es6/math';
import 'core-js/es6/string';
import 'core-js/es6/date';
import 'core-js/es6/array';
import 'core-js/es6/regexp';
import 'core-js/es6/map';
import 'core-js/es6/weak-map';
import 'core-js/es6/set';

But you might see a performance drop in IE browsers compared to others :(

With the kind help from Tim Williams, I finally figured out the last détails that were missing. Here's the final code below.

This question is a few years old, and there are some good suggestions for workarounds, but I didn't really notice any answers that address the core of the original question head-on. So:

• Providing a "universal" method for viewing source in a feature phone browser (or even arbitrary third-party smartphone browser) is impossible because "view source" — via any method — is a feature implemented in the browser. So how it's accessed, or even if it can be accessed, is up to the developers of the browser. I'm sure there are plenty of browsers that intentionally prevent the user from viewing page source, and if so then you're out of luck, except maybe for workarounds like the ones offered here.

• Workarounds such as "view source" apps external to the browser, while useful in some cases, are at best an imperfect partial solution to the original request. It's never certain that any such app will display the source of the page in the same form as it's loaded by the phone's browser.

  Modern web content changes itself in all manner of ways through browser detection, session management, etc. so that the source loaded by any external app can never be relied on to represent the source as loaded by a different app. If you're going to use an external app to load a page because you want to see the source, you might as well just use Chrome (or, on an iOS device, Safari) instead.

try: window.document......

var body = window.document.getElementsByTagName("body")[0];

here's an updated fiddle where the user's input is saved in local storage automatically. each time the fiddle is re-run or the page is refreshed the previous state is restored. this way you do not need to prompt users to save, it just saves on it's own.

http://jsfiddle.net/tZPg4/9397/

stack overflow requires I include some code with a jsFiddle link so please ignore snippet:

localStorage.setItem(...)

Actually your checkAll(..) is hanging without any attachment.

1) Add onchange event handler

<th><INPUT type="checkbox" onchange="checkAll(this)" name="chk[]" /> </th>

2) Modified the code to handle check/uncheck

 function checkAll(ele) {
     var checkboxes = document.getElementsByTagName('input');
     if (ele.checked) {
         for (var i = 0; i < checkboxes.length; i++) {
             if (checkboxes[i].type == 'checkbox') {
                 checkboxes[i].checked = true;
             }
         }
     } else {
         for (var i = 0; i < checkboxes.length; i++) {
             console.log(i)
             if (checkboxes[i].type == 'checkbox') {
                 checkboxes[i].checked = false;
             }
         }
     }
 }

Updated Fiddle

The first thing i noticed is that you have a semi colon just after your closing bracket for your if statement );

You should also try and clean up your if statement by declaring a variable for the answer separately.

function answers() {

var select = document.getElementById("mySelect");
var answer = select.options[select.selectedIndex].value;

    if(answer == "To measure time"){
        alert("Thats correct"); 
    }

}

As stated in other answers, you can check the mime type by checking the signature of the file in the first bytes of the file.

But what other answers are doing is loading the entire file in memory in order to check the signature, which is very wasteful and could easily freeze your browser if you select a big file by accident or not.

You simply need to use simpleCart

UPDATE just use the new way from @cminatti

old answer for historic purposes

IMO it's better to use select() and on() since that way you can have multiple resize event handlers... just don't get too crazy

d3.select(window).on('resize', resize); 

function resize() {
    // update width
    width = parseInt(d3.select('#chart').style('width'), 10);
    width = width - margin.left - margin.right;

    // resize the chart
    x.range([0, width]);
    d3.select(chart.node().parentNode)
        .style('height', (y.rangeExtent()[1] + margin.top + margin.bottom) + 'px')
        .style('width', (width + margin.left + margin.right) + 'px');

    chart.selectAll('rect.background')
        .attr('width', width);

    chart.selectAll('rect.percent')
        .attr('width', function(d) { return x(d.percent); });

    // update median ticks
    var median = d3.median(chart.selectAll('.bar').data(), 
        function(d) { return d.percent; });

    chart.selectAll('line.median')
        .attr('x1', x(median))
        .attr('x2', x(median));


    // update axes
    chart.select('.x.axis.top').call(xAxis.orient('top'));
    chart.select('.x.axis.bottom').call(xAxis.orient('bottom'));

}

You're declaring everything in the parent page. So the references to window and document are to the parent page's. If you want to do stuff to the iframe's, use iframe || iframe.contentWindow to access its window, and iframe.contentDocument || iframe.contentWindow.document to access its document.

There's a word for what's happening, possibly "lexical scope": What is lexical scope?

The only context of a scope is this. And in your example, the owner of the method is doc, which is the iframe's document. Other than that, anything that's accessed in this function that uses known objects are the parent's (if not declared in the function). It would be a different story if the function were declared in a different place, but it's declared in the parent page.

This is how I would write it:

(function () {
  var dom, win, doc, where, iframe;

  iframe = document.createElement('iframe');
  iframe.src = "javascript:false";

  where = document.getElementsByTagName('script')[0];
  where.parentNode.insertBefore(iframe, where);

  win = iframe.contentWindow || iframe;
  doc = iframe.contentDocument || iframe.contentWindow.document;

  doc.open();
  doc._l = (function (w, d) {
    return function () {
      w.vanishing_global = new Date().getTime();

      var js = d.createElement("script");
      js.src = 'test-vanishing-global.js?' + w.vanishing_global;

      w.name = "foobar";
      d.foobar = "foobar:" + Math.random();
      d.foobar = "barfoo:" + Math.random();
      d.body.appendChild(js);
    };
  })(win, doc);
  doc.write('<body onload="document._l();"></body>');
  doc.close();
})();

The aliasing of win and doc as w and d aren't necessary, it just might make it less confusing because of the misunderstanding of scopes. This way, they are parameters and you have to reference them to access the iframe's stuff. If you want to access the parent's, you still use window and document.

I'm not sure what the implications are of adding methods to a document (doc in this case), but it might make more sense to set the _l method on win. That way, things can be run without a prefix...such as <body onload="_l();"></body>

If you are looking to style a file input element, look at open file dialog box in javascript. If you are looking to grab the files associated with a file input element, you must do something like this:

inputElement.onchange = function(event) {
   var fileList = inputElement.files;
   //TODO do something with fileList.  
}

See this MDN article for more info on the FileList type.

Note that the code above will only work in browsers that support the File API. For IE9 and earlier, for example, you only have access to the file name. The input element has no files property in non-File API browsers.

Edit: please see my other answer, as you probably don't need this now.

As you said, in API levels 11+ a HTML5VideoFullScreen$VideoSurfaceView is passed. But I don't think you are right when you say that "it doens't have a MediaPlayer".

This is the way to reach the MediaPlayer instance from the HTML5VideoFullScreen$VideoSurfaceView instance using reflection:

@SuppressWarnings("rawtypes")
Class c1 = Class.forName("android.webkit.HTML5VideoFullScreen$VideoSurfaceView");
Field f1 = c1.getDeclaredField("this$0");
f1.setAccessible(true);

@SuppressWarnings("rawtypes")
Class c2 = f1.getType().getSuperclass();
Field f2 = c2.getDeclaredField("mPlayer");
f2.setAccessible(true);

Object ___html5VideoViewInstance = f1.get(focusedChild); // Look at the code in my other answer to this same question to see whats focusedChild

Object ___mpInstance = f2.get(___html5VideoViewInstance); // This is the MediaPlayer instance.

So, now you could set the onCompletion listener of the MediaPlayer instance like this:

OnCompletionListener ocl = new OnCompletionListener()
{
    @Override
    public void onCompletion(MediaPlayer mp)
    {
        // Do stuff
    }
};

Method m1 = f2.getType().getMethod("setOnCompletionListener", new Class[] { Class.forName("android.media.MediaPlayer$OnCompletionListener") });
m1.invoke(___mpInstance, ocl);

The code doesn't fail but I'm not completely sure if that onCompletion listener will really be called or if it could be useful to your situation. But just in case someone would like to try it.

Instead of replacing everything with innerHTML try:

document.body.appendChild(myExtraNode);

You can't use "disable" to disable a click event. I don't know how or if it worked in IE6-9, but it didn't work on Chrome, and it shouldn't work on IE10 like that.

You can disable the onclick event, too, by attaching an event that cancels:

;(function () {
    function cancel () { return false; };
    document.getElementById("test").disabled = true;
    var nodes = document.getElementById("test").getElementsByTagName('*');
    console.log(nodes);
    for (var i = 0; i < nodes.length; i++) {
        nodes[i].setAttribute('disabled', true);
        nodes[i].onclick = cancel;
    }
}());

Furthermore, setting "disabled" on a node directly doesn't necessarily add the attribute- using setAttribute does.

I had the same issue. My problem was it was missing “-Dfile.encoding=UTF8” argument under the JAVA_OPTION in statWeblogic.cmd file in WebLogic server.

Thanks to dee for the answer above with the Scrape() subroutine. The code worked perfectly as written, and I was able to then convert the code to work with the specific website I am trying to scrape.

I do not have enough reputation to upvote or to comment, but I do actually have some minor improvements to add to dee's answer:

1. You will need to add the VBA Reference via "Tools\References" to "Microsoft HTML Object Library in order for the code to compile.

2. I commented out the Browser.Visible line and added the comment as follows

   'if you need to debug the browser page, uncomment this line:
   'Browser.Visible = True
   

3. And I added a line to close the browser before Set Browser = Nothing:

   Browser.Quit
   

Thanks again dee!

ETA: this works on machines with IE9, but not machines with IE8. Anyone have a fix?

Found the fix myself, so came back here to post it. The ClassName function is available in IE9. For this to work in IE8, you use querySelectorAll, with a dot preceding the class name of the object you are looking for:

'Set repList = doc.getElementsByClassName("reportList") 'only works in IE9, not in IE8
Set repList = doc.querySelectorAll(".reportList")       'this works in IE8+

Recursively loop through and print out all the xml child tags in the document, in case you don't have to change the code to handle dynamic changes in xml, provided it's a well formed xml.

• Go to Facebook for developers dashboard
• Click My Apps and select your App from the dropdown.
  (If you haven't already created any app select "Add a New App" to create a new app).
• Go to App Setting > Basic Tab and then click "Add Platform" at bottom section.
• Select "Website" and the add the website to log in as the Site URL(e.g. mywebsite.com)
• If you are testing in local, you can even just give the localhost URL of your app.
  eg. http://localhost:8080/myfbsampleapp
• Save changes and you can now access Facebook information from http://localhost:8080/myfbsampleapp

I agree with alex about making sure the DOM is loaded. I also think that the submit button will trigger a refresh.

This is what I would do

<html>
<head>
<title>webpage</title>
</head>
<script type="text/javascript">
var myButton;
var myTextfield;

function setup() {
  myButton = document.getElementById("myButton");
  myTextfield = document.getElementById("myTextfield");
  myButton.onclick = function() {
    var userName = myTextfield.value;
    greetUser(userName);
    return false;
  }
}

function greetUser(userName) {
  var greeting = "Hello " + userName + "!";
  document.getElementsByTagName("h2")[0].innerHTML = greeting;
}

</script>
<body onload="setup()">
  <h2>Hello World!</h2>
  <p id="myParagraph">This is an example website</p>

  <form>
    <input type="text" id="myTextfield" placeholder="Type your name" />
    <input type="button" id="myButton" value="Go" />
  </form>
  </body>
</html>

have fun!

Use the same process. You already have the variable iDiv which still refers to the original element <div id='block'> you've created. You just need to create another <div> and call appendChild().

// Your existing code unmodified...
var iDiv = document.createElement('div');
iDiv.id = 'block';
iDiv.className = 'block';
document.getElementsByTagName('body')[0].appendChild(iDiv);

// Now create and append to iDiv
var innerDiv = document.createElement('div');
innerDiv.className = 'block-2';

// The variable iDiv is still good... Just append to it.
iDiv.appendChild(innerDiv);

http://jsfiddle.net/W4Sup/1/

The order of event creation doesn't have to be as I have it above. You can alternately append the new innerDiv to the outer div before you add both to the <body>.

var iDiv = document.createElement('div');
iDiv.id = 'block';
iDiv.className = 'block';

// Create the inner div before appending to the body
var innerDiv = document.createElement('div');
innerDiv.className = 'block-2';

// The variable iDiv is still good... Just append to it.
iDiv.appendChild(innerDiv);

// Then append the whole thing onto the body
document.getElementsByTagName('body')[0].appendChild(iDiv);

From the document.getElementsByTagName I guess you are running the javascript in a browser.

The traditional way to expose functionality to javascript running in the browser is calling a remote URL using AJAX. The X in AJAX is for XML, but nowadays everybody uses JSON instead of XML.

For example, using jQuery you can do something like:

$.getJSON('http://example.com/your/webservice?param1=x&param2=y', 
    function(data, textStatus, jqXHR) {
        alert(data);
    }
)

You will need to implement a python webservice on the server side. For simple webservices I like to use Flask.

A typical implementation looks like:

@app.route("/your/webservice")
def my_webservice():
    return jsonify(result=some_function(**request.args)) 

You can run IronPython (kind of Python.Net) in the browser with silverlight, but I don't know if NLTK is available for IronPython.

In my opinion, each time you can, you should use Array and its methods. They are much, much faster then looping over the whole DOM / wrapper, or pushing stuff into empty array. Majority of solutions presented here you can call Naive as described here (great article btw):

https://medium.com/@chuckdries/traversing-the-dom-with-filter-map-and-arrow-functions-1417d326d2bc

My solution: (live preview on Codepen: https://codepen.io/Nikolaus91/pen/wEGEYe)

const wrapper = document.getElementById('test') // take a wrapper by ID -> fastest
const itemsArray = Array.from(wrapper.children) // make Array from his children

const pickOne = itemsArray.map(item => { // loop over his children using .map() --> see MDN for more
   if(item.classList.contains('four')) // we place a test where we determine our choice
     item.classList.add('the-chosen-one') // your code here
})

public static void main(String[] args) throws IOException {
    String filePath = "/Users/myXml/VH181.xml";
    File xmlFile = new File(filePath);
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder dBuilder;
    try {
        dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(xmlFile);
        doc.getDocumentElement().normalize();
        printElement(doc);
        System.out.println("XML file updated successfully");
    } catch (SAXException | ParserConfigurationException e1) {
        e1.printStackTrace();
    }
}
private static void printElement(Document someNode) {
    NodeList nodeList = someNode.getElementsByTagName("choiceInteraction");
    for(int z=0,size= nodeList.getLength();z<size; z++) {
            String Value = nodeList.item(z).getAttributes().getNamedItem("id").getNodeValue();
            System.out.println("Choice Interaction Id:"+Value);
        }
    }

we Can try this code using method

Here is my solution:

chrome.runtime.onMessage.addListener(function(request, sender) {
        if (request.action == "getSource") {
            this.pageSource = request.source;
            var title = this.pageSource.match(/<title[^>]*>([^<]+)<\/title>/)[1];
            alert(title)
        }
    });

    chrome.tabs.query({ active: true, currentWindow: true }, tabs => {
        chrome.tabs.executeScript(
            tabs[0].id,
            { code: 'var s = document.documentElement.outerHTML; chrome.runtime.sendMessage({action: "getSource", source: s});' }
        );
    });

I created a jQuery version of PhpMyCoder's answer:

$('form').submit(function( e ) {    
    if(!($('#file')[0].files[0].size < 10485760 && get_extension($('#file').val()) == 'jpg')) { // 10 MB (this size is in bytes)
        //Prevent default and display error
        alert("File is wrong type or over 10Mb in size!");
        e.preventDefault();
    }
});

function get_extension(filename) {
    return filename.split('.').pop().toLowerCase();
}

You can't change or alter the actual :hover selector through Javascript. You can, however, use mouseenter to change the style, and revert back on mouseleave (thanks, @Bryan).

The percentage setting does not take into account the original image size. From w3schools :

In HTML 4.01, the width could be defined in pixels or in % of the containing element. In HTML5, the value must be in pixels.

Also, good practice advice from the same source :

Tip: Downsizing a large image with the height and width attributes forces a user to download the large image (even if it looks small on the page). To avoid this, rescale the image with a program before using it on a page.

No. You can't send headers after they were sent. Try to use hooks in wordpress

I'm using IronPython here (same as .NET API) and reading the file as UTF-8 in order to properly handle the BOM fixed the problem for me:

xmlFile = Path.Combine(directory_str, 'file.xml')
doc = XPathDocument(XmlTextReader(StreamReader(xmlFile.ToString(), Encoding.UTF8)))

It would work as well with the XmlDocument:

doc = XmlDocument()
doc.Load(XmlTextReader(StreamReader(xmlFile.ToString(), Encoding.UTF8)))

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

If you are adding the option with javascript

function AddNewOption(userRoutes, text, id) 
{
    var option = document.createElement("option");
    option.text = text;
    option.value = id;
    option.selected = "selected";
    userdRoutes.add(option);
}

I had a similar problem getting scrollTop to work after reload of div content. The content scrolled to top each time the procedure below was run. I found that a little delay before setting the new scrolltop solved the issue.

This is cut from wdCalendar where I modified this procedure:

 function BuildDaysAndWeekView(startday, l, events, config)
   ....
        var scrollpos = $("#dvtec").scrollTop();
        gridcontainer.html(html.join(""));
        setTimeout(function() {
            $("#dvtec").scrollTop(scrollpos);
        }, 25);
   ....

Without the delay, it simply did not work.

I'd suggest doing something similar to:

function show_sub(cat) {
    if (!cat) {
        return false;
    }
    else if (document.getElementById(cat)) {
        var parent = document.getElementById(cat),
            sub = parent.getElementsByClassName('sub');
        if (sub[0].style.display == 'inline'){
            sub[0].style.display = 'none';
        }
        else {
            sub[0].style.display = 'inline';
        }
    }
}

document.getElementById('cat').onclick = function(){
    show_sub(this.id);
};????

JS Fiddle demo.

Though the above relies on the use of a class rather than a name attribute equal to sub.

As to why your original version "didn't work" (not, I must add, a particularly useful description of the problem), all I can suggest is that, in Chromium, the JavaScript console reported that:

Uncaught TypeError: Object # has no method 'getElementsByName'.

One approach to working around the older-IE family's limitations is to use a custom function to emulate getElementsByClassName(), albeit crudely:

function eBCN(elem,classN){
    if (!elem || !classN){
        return false;
    }
    else {
        var children = elem.childNodes;
        for (var i=0,len=children.length;i<len;i++){
            if (children[i].nodeType == 1
                &&
                children[i].className == classN){
                    var sub = children[i];
            }
        }
        return sub;
    }
}

function show_sub(cat) {
    if (!cat) {
        return false;
    }
    else if (document.getElementById(cat)) {
        var parent = document.getElementById(cat),
            sub = eBCN(parent,'sub');
        if (sub.style.display == 'inline'){
            sub.style.display = 'none';
        }
        else {
            sub.style.display = 'inline';
        }
    }
}

var D = document,
    listElems = D.getElementsByTagName('li');
for (var i=0,len=listElems.length;i<len;i++){
    listElems[i].onclick = function(){
        show_sub(this.id);
    };
}?

If you are loading the XML file from a remote location, I would check to see if the file is actually being downloaded correctly using a sniffer like Fiddler.

I wrote a quick console app to run your code and parse the file and it works fine for me.

Using require.js you can do the same thing in a safer way. You can just define your dependency on jquery and then execute the code you want using the dependency when it is loaded without polluting the namespace:

I generally recommend this library for managing all dependencies on Javascript. It's simple and allows for an efficient optimization of resource loading. However there's some precautions you may need to take when using it with JQuery . My favourite way to deal with them is explained in this github repo and reflected by the following code sample:

<title>jQuery+RequireJS Sample Page</title>
   <script src="scripts/require.js"></script>
   <script>
   require({
       baseUrl: 'scripts',
       paths: {
           jquery: 'https://ajax.googleapis.com/ajax/libs/jquery/1.6.0/jquery.min'
       },
       priority: ['jquery']
    }, ['main']);
    </script>

First off, when you call getElementById, you need to provide an id. o_O

The only item in your dom with an id is the table element. If you can, you could add ids (make sure they are unique) to your tr elements.

Alternatively, you can use getElementsByTagName('tr') to get a list of tr elements in your document, and then get the number of tds.

here is a fiddle that console logs the results...

I am using the following code in one of my current projects where i download data from the internet. It is all inside my activity class.

private class GetData extends AsyncTask<String, Void, JSONObject> {

        @Override
        protected void onPreExecute() {
            super.onPreExecute();

            progressDialog = ProgressDialog.show(Calendar.this,
                    "", "");

        }

        @Override
        protected JSONObject doInBackground(String... params) {

            String response;

            try {

                HttpClient httpclient = new DefaultHttpClient();

                HttpPost httppost = new HttpPost(url);

                HttpResponse responce = httpclient.execute(httppost);

                HttpEntity httpEntity = responce.getEntity();

                response = EntityUtils.toString(httpEntity);

                Log.d("response is", response);

                return new JSONObject(response);

            } catch (Exception ex) {

                ex.printStackTrace();

            }

            return null;
        }

        @Override
        protected void onPostExecute(JSONObject result) 
        {
            super.onPostExecute(result);

            progressDialog.dismiss();

            if(result != null)
            {
                try
                {
                    JSONObject jobj = result.getJSONObject("result");

                    String status = jobj.getString("status");

                    if(status.equals("true"))
                    {
                        JSONArray array = jobj.getJSONArray("data");

                        for(int x = 0; x < array.length(); x++)
                        {
                            HashMap<String, String> map = new HashMap<String, String>();

                            map.put("name", array.getJSONObject(x).getString("name"));

                            map.put("date", array.getJSONObject(x).getString("date"));

                            map.put("description", array.getJSONObject(x).getString("description"));

                            list.add(map);
                        }

                        CalendarAdapter adapter = new CalendarAdapter(Calendar.this, list);

                        list_of_calendar.setAdapter(adapter);
                    }
                }
                catch (Exception e) 
                {
                    e.printStackTrace();
                }
            }
            else
            {
                Toast.makeText(Calendar.this, "Network Problem", Toast.LENGTH_LONG).show();
            }
        }

    }

and execute it in OnCreate Method like new GetData().execute();

where Calendar is my calendarActivity and i have also created a CalendarAdapter to set these values to a list view.

a bit example when playing video

  let v = document.getElementById('video-plan');
  v.onplay = function() {
      console.log('Start video')
  };

The solution that fixed mine was that I had inadvertently applied different keys to Encryption and Decryption methods.

var t = document.getElementById("table"),
    d = t.getElementsByTagName("tr"),
    r = d.getElementsByTagName("td");

needs to be:

var t = document.getElementById("table"),
    tableRows = t.getElementsByTagName("tr"),
    r = [], i, len, tds, j, jlen;

for ( i =0, len = tableRows.length; i<len; i++) {
    tds = tableRows[i].getElementsByTagName('td');
    for( j = 0, jlen = tds.length; j < jlen; j++) {
        r.push(tds[j]);
    }
}

Because getElementsByTagName returns a NodeList an Array-like structure. So you need to loop through the return nodes and then populate you r like above.

I used the System.Xml.Linq.XElement for the purpose. Just check code below for reading the value of first child node of the xml(not the root node).

        string textXml = "<xmlroot><firstchild>value of first child</firstchild>........</xmlroot>";
        XElement xmlroot = XElement.Parse(textXml);
        string firstNodeContent = ((System.Xml.Linq.XElement)(xmlroot.FirstNode)).Value;

The problem is that when you add a parameter to DOMDocument::saveHTML() function, you lose the encoding. In a few cases, you'll need to avoid the use of the parameter and use old string function to find what your are looking for.

I think the previous answer works for you, but since this workaround didn't work for me, I'm adding that answer to help people who may be in my case.

Its Simple to implement Just need javasript methods in your html to get value of html content. As Above your code some changes to be need.

  public class htmldecoder extends Activity implements OnClickListener,TextWatcher
    {
    Button btsubmit; // this button in your xml file
    WebView wvbrowser;
    public void onCreate(Bundle savedInstanceState)
    {
                super.onCreate(savedInstanceState);
                    setContentView(R.layout.htmldecoder);



        btsubmit=(Button)findViewById(R.id.btsubmit);
        btsubmit.setOnClickListener(this);

        wvbrowser=(WebView)findViewById(R.id.wvbrowser);
        wvbrowser.setWebViewClient(new HelloWebViewClient());
        wvbrowser.getSettings().setJavaScriptEnabled(true);
        wvbrowser.getSettings().setPluginsEnabled(true);
        wvbrowser.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        MyJavaScriptInterface myinterface=new MyJavaScriptInterface();
        wvbrowser.addJavascriptInterface(myinterface,"interface");
        webView.loadUrl("file:///android_asset/simple.html");  //use one html file for //testing put your html file in assets. Make sure that you done JavaScript methods to get //values for html content in html file . 
   }
   public void onClick(View v)
{
    if(btsubmit==v)
    {

        webView.loadUrl("javascript:showalert()");// call javascript method.  
        //wvbr
    }
}

final class MyJavaScriptInterface {



        MyJavaScriptInterface() {

        }

        public void sendValueFromHtml(String value) {
           System.out.println("Here is the value from html::"+value);
        }

    }

}

Your Javascript in html

 <script type="text/javascript">
    //<![CDATA[
    var n1;
    function callme(){
    n1=document.getElementById("FacadeAL").value;
    }
    function showalert(){
     window.interface.sendValueFromHtml(n1);// this method calling the method of interface which //you attached to html file in android. // & we called this showalert javasript method on //submmit buttton click of android. 
    }
    //]]>
    </script>

& Make sure you calling callme like below in html

<input name="FacadeAL" id="FacadeAL" type="text" size="5" onblur="callme()"/>
Hope this will help you.

In my case an unexpected error notice in the source code stopped the facebook crawler from parsing the (correctly set) og-meta tags.

I was using the HTTP_ACCEPT_LANGUAGE header, which worked fine for regular browser requests but not for the crawler, as it obviously won't use/set it.

Therefore, it was crucial for me to use the facebook's debugger feature See exactly what our scraper sees for your URL, as the error notice only could only be seen there (but not through the regular 'view source code'-browser feature).

One reason why your scripts could be loading so slowly is if you were running all of your scripts while loading the page, like this:

callMyFunctions();

instead of:

$(window).load(function() {
      callMyFunctions();
});

This second bit of script waits until the browser has completely loaded all of your Javascript code before it starts executing any of your scripts, making it appear to the user that the page has loaded faster.

If you're looking to enhance the user's experience by decreasing the loading time, I wouldn't go for the "loading screen" option. In my opinion that would be much more annoying than just having the page load more slowly.

Just another answer

Array.prototype.filter.call(
    document.getElementsByTagName('span'),
    function(el) {return el.getAttribute('property') == 'v.name';}
);

In future

Array.prototype.filter.call(
    document.getElementsByTagName('span'),
    (el) => el.getAttribute('property') == 'v.name'
)

3rd party edit

Intro

• The call() method calls a function with a given this value and arguments provided individually.

• The filter() method creates a new array with all elements that pass the test implemented by the provided function.

Given this html markup

<span property="a">apple - no match</span>
<span property="v:name">onion - match</span>
<span property="b">root - match</span>
<span property="v:name">tomato - match</span>
<br />
<button onclick="findSpan()">find span</button>

you can use this javascript

function findSpan(){

    var spans = document.getElementsByTagName('span');
    var spansV = Array.prototype.filter.call(
         spans,
         function(el) {return el.getAttribute('property') == 'v:name';}
    );
    return spansV;
}

Got it :D

function getContextPath() {
   return window.location.pathname.substring(0, window.location.pathname.indexOf("/",2));
}
alert(getContextPath());

Important note: Does only work for the "root" context path. Does not work with "subfolders", or if context path has a slash ("/") in it.

I would suggest using a different approach. Add a button on the webpage that will copy the content of the table to the clipboard, with TAB chars between columns and newlines between rows. This way the "paste" function in Excel should work correctly and your web application will also work with many browsers and on many operating systems (linux, mac, mobile) and users will be able to use the data also with other spreadsheets or word processing programs.

The only tricky part is to copy to the clipboard because many browsers are security obsessed on this. A solution is to prepare the data already selected in a textarea, and show it to the user in a modal dialog box where you tell the user to copy the text (some will need to type Ctrl-C, others Command-c, others will use a "long touch" or a popup menu).

It would be nicer to have a standard copy-to-clipboard function that possibly requests a user confirmation... but this is not the case, unfortunately.

Change the order of statments. For me, changing the block of code

xsi:schemaLocation="http://www.springframework.org/schema/beans 
                    http://www.springframework.org/schema/context
                    http://www.springframework.org/schema/beans/spring-beans.xsd" 

with

xsi:schemaLocation="http://www.springframework.org/schema/beans 
                    http://www.springframework.org/schema/beans/spring-beans.xsd
                    http://www.springframework.org/schema/context"

is valid.

function loadpage (page_request, containerid)
{
  var loading = document.getElementById ( "loading" ) ;

  // when connecting to server
  if ( page_request.readyState == 1 )
      loading.style.visibility = "visible" ;

  // when loaded successfully
  if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
  {
      document.getElementById(containerid).innerHTML=page_request.responseText ;
      loading.style.visibility = "hidden" ;
  }
}

$('#yourTextBoxId').live('change keyup paste', function(){
    if ($('#yourTextBoxId').val().length > 11) {
        $('#yourTextBoxId').val($('#yourTextBoxId').val().substr(0,10));
    }
});

I Used this along with vars and selectors caching for performance and that did the trick ..

If the Node is not just any node, but actually an Element (it could also be e.g. an attribute or a text node), you can cast it to Element and use getElementsByTagName.

Try moving the OGG source to the top. I've noticed Firefox sometimes gets confused and stops the player when the one it wants to play, OGG, isn't first.

Worth a try.

You should really use the following instead (works in all newer browsers):

window.addEventListener('DOMContentLoaded', init, false);

In pure vanilla Javascript, without jQuery or ES6, you could do:

const elements = document.getElementsByClassName("my-class");

while (elements.length > 0) elements[0].remove();

First, get all the elements

const getAllFormElements = element => Array.from(element.elements).filter(tag => ["select", "textarea", "input"].includes(tag.tagName.toLowerCase()));

Second, do something with them

const pageFormElements = getAllFormElements(document.body);
console.log(pageFormElements);

If you want to use a form, rather than the entire body of the page, you can do it like this

const pageFormElements = getAllFormElements(document.getElementById("my-form"));
console.log(formElements);

How about:

import java.io.File;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;
import org.w3c.dom.NodeList;

public class Demo {

    public static void main(String[] args) throws Exception {
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        Document document = db.parse(new File("input.xml"));
        NodeList nodeList = document.getElementsByTagName("Item");
        for(int x=0,size= nodeList.getLength(); x<size; x++) {
            System.out.println(nodeList.item(x).getAttributes().getNamedItem("name").getNodeValue());
        }
    }
}

Here's a simple way.

/**
 * Add css to the document
 * @param {string} css
 */
function addCssToDocument(css){
  var style = document.createElement('style')
  style.innerText = css
  document.head.appendChild(style)
}

Asynchronous programming is slightly more complicated because the consequence of making a request is encapsulated in a function instead of following the request statement. But the realtime behavior that the user experiences can be significantly better because they will not see a sluggish server or sluggish network cause the browser to act as though it had crashed. Synchronous programming is disrespectful and should not be employed in applications which are used by people.

Douglas Crockford (YUI Blog)

Alright, buckle your seats, because it's going to be a bumpy ride. More and more people ask about loading scripts dynamically via javascript, it seems to be a hot topic.

The main reasons why this became so popular are:

• client-side modularity
• easier dependency management
• error handling
• performance advantages

About modularity: it is obvious that managing client-side dependencies should be handled right on the client-side. If a certain object, module or library is needed we just ask for it and load it dynamically.

Error handling: if a resource fails we still get the chance to block only the parts that depend on the affected script, or maybe even give it another try with some delay.

Performance has become a competitive edge between websites, it is now a search ranking factor. What dynamic scripts can do is mimic asynchronous behavior as opposed to the default blocking way of how browsers handle scripts. Scripts block other resources, scripts block further parsing of the HTML document, scripts block the UI. Now with dynamic script tags and its cross-browser alternatives you can do real asynchronous requests, and execute dependent code only when they are available. Your scripts will load in-parallel even with other resources and the rendering will be flawless.

The reason why some people stick to synchronous scripting is because they are used to it. They think it is the default way, it is the easier way, and some may even think it is the only way.

But the only thing we should care about when this needs to be decided concerning an applications's design is the end-user experience. And in this area asynchronous cannot be beaten. The user gets immediate responses (or say promises), and a promise is always better than nothing. A blank screen scares people. Developers shouldn't be lazy to enhance perceived performance.

And finally some words about the dirty side. What you should do in order to get it working across browsers:

1. learn to think asynchronously
2. organize your code to be modular
3. organize your code to handle errors and edge cases well
4. enhance progressively
5. always take care of the right amount of feedback

If you use CDATA, you could embed the line breaks directly into the XML I think. Example:

<song>
    <title>Song Title</title>
    <lyric><![CDATA[Line 1
Line 2
Line 3]]></lyric>
</song>

If I'm understanding your question and code correctly, then I want to first mention three things before sharing my code/version of a solution. First, for both name and value you probably shouldn't be using the getAttribute() method because they are, themselves, properties of (the variable named) inputs (at a given index of i). Secondly, the variable that you are trying to alert is one of a select handful of terms in JavaScript that are designated as 'reserved keywords' or simply "reserved words". As you can see in/on this list (on the link), new is clearly a reserved word in JS and should never be used as a variable name. For more information, simply google 'reserved words in JavaScript'. Third and finally, in your alert statement itself, you neglected to include a semicolon. That and that alone can sometimes be enough for your code not to run as expected. [Aside: I'm not saying this as advice but more as observation: JavaScript will almost always forgive and allow having too many and/or unnecessary semicolons, but generally JavaScript is also equally if not moreso merciless if/when missing (any of the) necessary, required semicolons. Therefore, best practice is, of course, to add the semicolons only at all of the required points and exclude them in all other circumstances. But practically speaking, if in doubt, it probably will not hurt things by adding/including an extra one but will hurt by ignoring a mandatory one. General rules are all declarations and assignments end with a semicolon (such as variable assignments, alerts, console.log statements, etc.) but most/all expressions do not (such as for loops, while loops, function expressions Just Saying.] But I digress..

    function whenWindowIsReady() {
        var inputs = document.getElementsByTagName('input');
        var lengthOfInputs = inputs.length; // this is for optimization
        for (var i = 0; i < lengthOfInputs; i++) {
            if (inputs[i].name === "ans") {   
                var ansIsName = inputs[i].value;
                alert(ansIsName);
            }
        }
    }

    window.onReady = whenWindowIsReady();

PS: You used a double assignment operator in your conditional statement, and in this case it doesn't matter since you are comparing Strings, but generally I believe the triple assignment operator is the way to go and is more accurate as that would check if the values are EQUIVALENT WITHOUT TYPE CONVERSION, which can be very important for other instances of comparisons, so it's important to point out. For example, 1=="1" and 0==false are both true (when usually you'd want those to return false since the value on the left was not the same as the value on the right, without type conversion) but 1==="1" and 0===false are both false as you'd expect because the triple operator doesn't rely on type conversion when making comparisons. Keep that in mind for the future.

Try this snippet:

function stripAndExecuteScript(text) {
    var scripts = '';
    var cleaned = text.replace(/<script[^>]*>([\s\S]*?)<\/script>/gi, function(){
        scripts += arguments[1] + '\n';
        return '';
    });

    if (window.execScript){
        window.execScript(scripts);
    } else {
        var head = document.getElementsByTagName('head')[0];
        var scriptElement = document.createElement('script');
        scriptElement.setAttribute('type', 'text/javascript');
        scriptElement.innerText = scripts;
        head.appendChild(scriptElement);
        head.removeChild(scriptElement);
    }
    return cleaned;
};


var scriptString = '<scrip' + 't + type="text/javascript">alert(\'test\');</scr' + 'ipt><strong>test</strong>';
document.getElementById('element').innerHTML = stripAndExecuteScript(scriptString);

This is an answer based on jluckyiv's, but I think it is better and simpler to change Javascript as follows.

browser.loadUrl("javascript:HTMLOUT.processHTML(document.documentElement.outerHTML);");

Something like this.

function addRowHandlers() {
  var table = document.getElementById("tableId");
  var rows = table.getElementsByTagName("tr");
  for (i = 0; i < rows.length; i++) {
    var currentRow = table.rows[i];
    var createClickHandler = function(row) {
      return function() {
        var cell = row.getElementsByTagName("td")[0];
        var id = cell.innerHTML;
        alert("id:" + id);
      };
    };
    currentRow.onclick = createClickHandler(currentRow);
  }
}

EDIT

Working demo.

If you actually want this code to run at load, not at domready (ie you need the images to be loaded as well), then unfortunately the ready function doesn't do it for you. I generally just do something like this:

Include in document javascript (ie always called before onload fired):

var pageisloaded=0;
window.addEvent('load',function(){
 pageisloaded=1;
});

Then your code:

if (pageisloaded) {
 DoStuffFunction();
} else {
 window.addEvent('load',DoStuffFunction);
}

(Or the equivalent in your framework of preference.) I use this code to do precaching of javascript and images for future pages. Since the stuff I'm getting isn't used for this page at all, I don't want it to take precedence over the speedy download of images.

There may be a better way, but I've yet to find it.

XmlDocument.Attributes perhaps? (Which has a method GetNamedItem that will presumably do what you want, although I've always just iterated the attribute collection)

For anyone using Ember, this should work as expected:

<iframe onLoad={{action 'actionName'}}  frameborder='0' src={{iframeSrc}} />

While this question is old and answered, I have yet another fairly interesting solution:

var funcs = [];

for (var i = 0; i < 3; i++) {     
  funcs[i] = function() {          
    console.log("My value: " + i); 
 };
}

for (var i = 0; i < 3; i++) {
  funcs[i]();
}

The change is so small it's almost difficult to see what I did. I switched the second iterator from a j to an i. This somehow refreshes the state of i in time to give you the desired result. I did this by accident but it makes sense considering previous answers.

I wrote this up to point out this small, yet very important difference. Hope that helps to clear up some confusion for other learners like me.

Note: I am not sharing this because I think it's the right answer. This is a flakey solution that probably will break under certain circumstances. Actually, I'm quite amazed that it really works.

my working clean solution (2017)

function loaderScript(scriptUrl){
   return new Promise(function (res, rej) {
    let script = document.createElement('script');
    script.src = scriptUrl;
    script.type = 'text/javascript';
    script.onError = rej;
    script.async = true;
    script.onload = res;
    script.addEventListener('error',rej);
    script.addEventListener('load',res);
    document.head.appendChild(script);
 })

}

As Martin pointed, used like that:

const event = loaderScript("myscript.js")
  .then(() => { console.log("loaded"); })
  .catch(() => { console.log("error"); });

OR

try{
 await loaderScript("myscript.js")
 console.log("loaded"); 
}catch{
 console.log("error");
}

Since scripts are executed sequentially, the currently executed script tag is always the last script tag on the page until then. So, to get the script tag, you can do:

var scripts = document.getElementsByTagName( 'script' );
var thisScriptTag = scripts[ scripts.length - 1 ];

The above answer is correct, namely:

name[0].firstChild.nodeValue

However for me, like others, my value was further down the tree:

name[0].firstChild.firstChild.nodeValue

To find this I used the following:

def scandown( elements, indent ):
    for el in elements:
        print("   " * indent + "nodeName: " + str(el.nodeName) )
        print("   " * indent + "nodeValue: " + str(el.nodeValue) )
        print("   " * indent + "childNodes: " + str(el.childNodes) )
        scandown(el.childNodes, indent + 1)

scandown( doc.getElementsByTagName('text'), 0 )

Running this for my simple SVG file created with Inkscape this gave me:

nodeName: text
nodeValue: None
childNodes: [<DOM Element: tspan at 0x10392c6d0>]
   nodeName: tspan
   nodeValue: None
   childNodes: [<DOM Text node "'MY STRING'">]
      nodeName: #text
      nodeValue: MY STRING
      childNodes: ()
nodeName: text
nodeValue: None
childNodes: [<DOM Element: tspan at 0x10392c800>]
   nodeName: tspan
   nodeValue: None
   childNodes: [<DOM Text node "'MY WORDS'">]
      nodeName: #text
      nodeValue: MY WORDS
      childNodes: ()

I used xml.dom.minidom, the various fields are explained on this page, MiniDom Python.

I had a very similar problem earlier with document.getElementsByClassName(). I didn't know what a nodelist was at the time.

var elements = document.getElementsByTagName('div');
for (var i=0; i<elements.length; i++) {
    doSomething(elements[i]);
}

My issue was that I expected that elements would be an array, but it isn't. The nodelist Document.getElementsByTagName() returns is iterable, but you can't call array.prototype methods on it.

You can however populate an array with nodelist elements like this:

var myElements = [];
for (var i=0; i<myNodeList.length; i++) {                               
    var element = myNodeList[i];
    myElements.push(element);
};

After that you can feel free to call .innerHTML or .style or something on the elements of your array.

If all you really want is to run javascript, this would be easiest (VB .Net):

MyWebBrowser.Navigate("javascript:function foo(){alert('hello');}foo();")

I guess that this wouldn't "inject" it but it'll run your function, if that's what you're after. (Just in case you've over-complicated the problem.) And if you can figure out how to inject in javascript, put that into the body of the function "foo" and let the javascript do the injection for you.

DAYS(start_date,end_date):

For example:

DAYS(A1,TODAY())

From the Sublime Text docs for Windows/Linux:

Keypress            Command
Ctrl + K, Ctrl + U  Transform to Uppercase
Ctrl + K, Ctrl + L  Transform to Lowercase

and for Mac:

Keypress    Command
cmd + KU    Transform to Uppercase
cmd + KL    Transform to Lowercase

Also note that Ctrl + Shift + p in Windows (? + Shift + p in a Mac) brings up the Command Palette where you can search for these and other commands. It looks like this:

I tested this in Firefox with Firebug using code like this:

console.time("testEquality");
var n = 0;
while (true) {
  n++;
  if (n == 100000)
    break;
}
console.timeEnd("testEquality");

and

console.time("testTypeEquality");
var n = 0;
while (true) {
  n++;
  if (n === 100000)
    break;
}
console.timeEnd("testTypeEquality");

My results (tested five times each and averaged):

==: 115.2
===: 114.4

So I'd say that the miniscule difference (this is over 100000 iterations, remember) is negligible. Performance isn't a reason to do ===. Type safety (well, as safe as you're going to get in JavaScript), and code quality is.

Well, this solution might sound very silly, but can save you in certain conditions.

A friend of mine just ran into accidentally committing very some huge files (four auto-generated files ranging between 3GB to 5GB each) and then made some additional code commits on top of that before realizing the problem that git push wasn't working any longer!

The files had been listed in .gitignore but after renaming the container folder, they got exposed and committed! And now there were a few more commits of the code on top of that, but push was running forever (trying to upload GB of data!) and finally would fail due to Github's file size limits.

The problem with interactive rebase or anything similar was that they would deal with poking around these huge files and would take forever to do anything. Nevertheless, after spending almost an hour in the CLI, we weren't sure if the files (and deltas) are actually removed from the history or simply not included in the current commits. The push wasn't working either and my friend was really stuck.

So, the solution I came up with was:

1. Rename current git folder to ~/Project-old.
2. Clone the git folder again from github (to ~/Project).
3. Checkout to the same branch.
4. Manually cp -r the files from ~/Project-old folder to ~/Project.
5. Make sure the massive files, that are not needed to be checked in are mved, and included in .gitignore properly.
6. Also make sure you don't overwrite .git folder in the recently-cloned ~/Project by the old one. That's where the logs of the problematic history lives!
7. Now review the changes. It should be the union of all the recent commits, excluding the problematic files.
8. Finally commit the changes, and it's good to be push'ed.

The biggest problem with this solution is, it deals with manual copying some files, and also it merges all the recent commits into one (obviously with a new commit-hash.) B

The big benefits are that, it is very clear in every step, it works great for huge files (as well as sensitive ones), and it doesn't leave any trace in history behind!

You have to fetch that one record, it will contain the result of Count()

$result = $db->query("SELECT COUNT(*) FROM `table`");
$row = $result->fetch_row();
echo '#: ', $row[0];

I was trying to format the date string received from a JSON response e.g. 2016-03-09T04:50:00-0800 to yyyy-MM-dd. So here's what I tried and it worked and helped me assign the formatted date string a calendar widget.

String DATE_FORMAT_I = "yyyy-MM-dd'T'HH:mm:ss";
String DATE_FORMAT_O = "yyyy-MM-dd";


SimpleDateFormat formatInput = new SimpleDateFormat(DATE_FORMAT_I);
SimpleDateFormat formatOutput = new SimpleDateFormat(DATE_FORMAT_O);

Date date = formatInput.parse(member.getString("date"));
String dateString = formatOutput.format(date);

This worked. Thanks.

Based on William McBrine's answer, here is a solution for fixed-length strings which is 9% faster for my use case:

import itertools
import struct
def make_strxor(size):
    def strxor(a, b, izip=itertools.izip, pack=struct.pack, unpack=struct.unpack, fmt='%dB' % size):
        return pack(fmt, *(a ^ b for a, b in izip(unpack(fmt, a), unpack(fmt, b))))
    return strxor
strxor_3 = make_strxor(3)
print repr(strxor_3('foo', 'bar'))

Use .toInt() for int .toFloat() for float and .toDouble() for double

toInt();

The solution below works very well for me.

Only 4 lines and works with most (all?) characters.

Solution:

:Trim
SetLocal EnableDelayedExpansion
set Params=%*
for /f "tokens=1*" %%a in ("!Params!") do EndLocal & set %1=%%b
exit /b

Test:

@echo off

call :Test1 & call :Test2 & call :Test3 & exit /b

:Trim
SetLocal EnableDelayedExpansion
set Params=%*
for /f "tokens=1*" %%a in ("!Params!") do EndLocal & set %1=%%b
exit /b

:Test1
set Value=   a b c   
set Expected=a b c
call :Trim Actual %Value%
if "%Expected%" == "%Actual%" (echo Test1 passed) else (echo Test1 failed)
exit /b

:Test2
SetLocal EnableDelayedExpansion
set Value=   a \ / : * ? " ' < > | ` ~ @ # $ [ ] & ( ) + - _ = z    
set Expected=a \ / : * ? " ' < > | ` ~ @ # $ [ ] & ( ) + - _ = z
call :Trim Actual !Value!
if !Expected! == !Actual! (echo Test2 passed) else (echo Test2 failed)
exit /b

:Test3
set /p Value="Enter string to trim: " %=%
echo Before: [%Value%]
call :Trim Value %Value%
echo After : [%Value%]
exit /b

Try this if you are using virtual enviroment :-

python manage.py shell

for using those command you must be inside virtual enviroment. for this use :-

This convention is used for special variables or methods (so-called “magic method”) such as __init__ and __len__. These methods provides special syntactic features or do special things.

For example, __file__ indicates the location of Python file, __eq__ is executed when a == b expression is executed.

A user of course can make a custom special method, which is a very rare case, but often might modify some of the built-in special methods (e.g. you should initialize the class with __init__ that will be executed at first when an instance of a class is created).

class A:
    def __init__(self, a):  # use special method '__init__' for initializing
        self.a = a
    def __custom__(self):  # custom special method. you might almost do not use it
        pass

dplyr

packages is always a saver in case of data wrangling. To add the desired division as a third variable I would use mutate()

d <- mutate(d, new = min / count2.freq)

The best way is to use menu mnemonics, i.e. to have menu entries in your main form that get assigned the keyboard shortcut you want. Then everything else is handled internally and all you have to do is to implement the appropriate action that gets executed in the Click event handler of that menu entry.

I faced a similar problem, trying to test if jQuery is already present on a page, and if not force it's load, and then execute a function. I tried with @David Hellsing workaround, but with no chance for my needs. In fact, the onload instruction was immediately evaluated, and then the $ usage inside this function was not yet possible (yes, the huggly "$ is not a function." ^^).

So, I referred to this article : https://developer.mozilla.org/fr/docs/Web/Events/load and attached a event listener to my script object.

var script = document.createElement('script');
script.type = "text/javascript";
script.addEventListener("load", function(event) {
    console.log("script loaded :)");
    onjqloaded();
});
script.src = "https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(script);

For my needs, it works fine now. Hope this can help others :)

I can't get it to work on $.get() because it has no complete event.

I suggest to use $.ajax() like this,

$.ajax({
    url: 'http://www.example.org',
    data: {'a':1,'b':2,'c':3},
    dataType: 'xml',
    complete : function(){
        alert(this.url)
    },
    success: function(xml){
    }
});

I think your assignment is backwards:

a[i] = b[i];

should be:

b[i] = a[i];

Use the CheckBoxList's GetItemChecked or GetItemCheckState method to find out whether an item is checked or not by its index.

You only need these CSS properties in .container class of Bootstrap and you can put inside him the normal grid system without someone content of the container will be out of him (without scroll-x in the viewport).

HTML:

<div class="container">
    <div class="row">
        <div class="col-xs-12">
            Your content here!
            ...    
        </div>
    </div>
    ... more rows
</div>

CSS:

/* Bootstrap custom */
.container{
    padding-left: 0rem;
    padding-right: 0rem;
    overflow: hidden;
}

For me the best option is to use CSS pseudo elements, so for disc bullet styling it would look like that:

ul {_x000D_
  list-style-type: none;_x000D_
}_x000D_
_x000D_
li {_x000D_
  position: relative;_x000D_
}_x000D_

For more bullets styles you may use other css shapes https://css-tricks.com/examples/ShapesOfCSS/ (choose this which doesn't require pseudo elements to work, so for example triangles)

Step 1

We need set format data in function date(): Function date() returns a string formatted according to the givenformat string using the given integer timestamp or the current time ifno timestamp is given. In other words, timestampis optional anddefaults to the value of time().

<?php
echo date("F j, Y");
?>

result: March 30, 2010

Step 2

For "yesterday" date use php function mktime(): Function mktime() returns the Unix timestamp corresponding to thearguments given. This timestamp is a long integer containing the numberof seconds between the Unix Epoch (January 1 1970 00:00:00 GMT) and thetime specified. Arguments may be left out in order from right to left; any argumentsthus omitted will be set to the current value according to the localdate and time.

<?php
echo mktime(0, 0, 0, date("m"), date("d")-1, date("Y"));
?>

result: 1269820800

Step 3

Now merge all and look at this:

<?php
$yesterday = date("Y-m-d", mktime(0, 0, 0, date("m") , date("d")-1,date("Y")));
echo $yesterday;
?>

result: March 29, 2010

Operating similarly, it is possible to receive time hour back.

<?php
$yesterday = date("H:i:s",mktime(date("H"), 0, 0, date("m"),date("d"), date("Y")));
echo $yesterday;
?>

result: 20:00:00

or 7 days ago:

<?php
$week = date("Y-m-d",mktime(0, 0, 0, date("m"), date("d")-7,date("Y")));
echo $week;
?>

result: 2010-03-23

Look here, the operator used is !!.

I.e. [1,2,3]!!1 gives you 2, since lists are 0-indexed.

No, this is not possible. In documents that make use of CSS, an inline style attribute can only contain property declarations; the same set of statements that appears in each ruleset in a stylesheet. From the Style Attributes spec:

The value of the style attribute must match the syntax of the contents of a CSS declaration block (excluding the delimiting braces), whose formal grammar is given below in the terms and conventions of the CSS core grammar:

declaration-list
  : S* declaration? [ ';' S* declaration? ]*
  ;

Neither selectors (including pseudo-elements), nor at-rules, nor any other CSS construct are allowed.

Think of inline styles as the styles applied to some anonymous super-specific ID selector: those styles only apply to that one very element with the style attribute. (They take precedence over an ID selector in a stylesheet too, if that element has that ID.) Technically it doesn't work like that; this is just to help you understand why the attribute doesn't support pseudo-class or pseudo-element styles (it has more to do with how pseudo-classes and pseudo-elements provide abstractions of the document tree that can't be expressed in the document language).

Note that inline styles participate in the same cascade as selectors in rule sets, and take highest precedence in the cascade (!important notwithstanding). So they take precedence even over pseudo-class states. Allowing pseudo-classes or any other selectors in inline styles would possibly introduce a new cascade level, and with it a new set of complications.

Note also that very old revisions of the Style Attributes spec did originally propose allowing this, however it was scrapped, presumably for the reason given above, or because implementing it was not a viable option.

To test the error handling, you can do something like this:

feature ErrorHandling do
  before do
    Rails.application.config.consider_all_requests_local = false
    Rails.application.config.action_dispatch.show_exceptions = true
  end

  scenario 'renders not_found template' do
    visit '/blah'
    expect(page).to have_content "The page you were looking for doesn't exist."
  end
end

Just try $('.handle').css('left', '300px');

After python 3.6, you can use formatted string literal. It's neat! (https://docs.python.org/3/whatsnew/3.6.html#whatsnew36-pep498)

try
 ...
except Exception as e:
    logger.error(f"Failed to upload to ftp: {e}")

Unfortunately there really isn't a set set of escape codes since it varies based on the language you are using.

However, keeping a page like the Regular Expression Tools Page or this Regular Expression Cheatsheet can go a long way to help you quickly filter things out.

I found the above answers quite useful but not really general purpose, they all need some other major build system like Ant or Maven.

I wanted to generate a report in a simple one-shot command that I could call from anything (from a build, test or just myself) so I have created junit2html which can be found here: https://github.com/inorton/junit2html

You can install it by doing:

pip install junit2html

Only first part of Justin's answer is correct. Using "%.3g" will not work for all cases as .3 is not the precision, but total number of digits. Try it for numbers like 1000.123 and it breaks.

So, I would use what Justin is suggesting:

>>> ('%.4f' % 12340.123456).rstrip('0').rstrip('.')
'12340.1235'
>>> ('%.4f' % -400).rstrip('0').rstrip('.')
'-400'
>>> ('%.4f' % 0).rstrip('0').rstrip('.')
'0'
>>> ('%.4f' % .1).rstrip('0').rstrip('.')
'0.1'

Probably you are trying to access the excel with the index 0, please note that Excel rows/columns start from 1.

How about this

let numbers = [1,2,3,4,5]
numbers.forEach((number, index) => console.log(`${index}:${number}`))

Where array.forEach this method has an index parameter which is the index of the current element being processed in the array.

Try if that works

sc = spark.sparkContext

# Infer the schema, and register the DataFrame as a table.
schemaPeople = spark.createDataFrame(RddName)
schemaPeople.createOrReplaceTempView("RddName")

You need to define propTypes as a static getter if you want it inside the class declaration:

static get propTypes() { 
    return { 
        children: PropTypes.any, 
        onClickOut: PropTypes.func 
    }; 
}

If you want to define it as an object, you need to define it outside the class, like this:

IxClickOut.propTypes = {
    children: PropTypes.any,
    onClickOut: PropTypes.func,
};

Also it's better if you import prop types from prop-types, not react, otherwise you'll see warnings in console (as preparation for React 16):

import PropTypes from 'prop-types';

Update: I should have probably started with this as your projects are SNAPSHOTs. It is part of the SNAPSHOT semantics that Maven will check for updates on each build. Being a SNAPSHOT means that it is volatile and subject to change so updates should be checked for. However it's worth pointing out that the Maven super POM configures central to have snapshots disabled, so Maven shouldn't ever check for updates for SNAPSHOTs on central unless you've overridden that in your own pom/settings.

You can configure Maven to use a mirror for the central repository, this will redirect all requests that would normally go to central to your internal repository.

In your settings.xml you would add something like this to set your internal repository as as mirror for central:

<mirrors>
  <mirror>
    <id>ibiblio.org</id>
    <name>ibiblio Mirror of http://repo1.maven.org/maven2/</name>
    <url>http://path/to/my/repository</url>
    <mirrorOf>central</mirrorOf>
  </mirror>
</mirrors>

If you are using a repository manager like Nexus for your internal repository. You can set up a proxy repository for proxy central, so any requests that would normally go to Central are instead sent to your proxy repository (or a repository group containing the proxy), and subsequent requests are cached in the internal repository manager. You can even set the proxy cache timeout to -1, so it will never request for contents from central that are already on the proxy repository.

A more basic solution if you are only working with local repositories is to set the updatePolicy for the central repository to "never", this means Maven will only ever check for artifacts that aren't already in the local repository. This can then be overridden at the command line when needed by using the -U switch to force Maven to check for updates.

You would configure the repository (in your pom or a profile in the settings.xml) as follows:

<repository>
  <id>central</id>
  <url>http://repo1.maven.org/maven2</url>
  <updatePolicy>never</updatePolicy>
</repository>

First of all you need to remove the data-toggle attribute. We will use some JQuery, so make sure you include it.

  <ul class='nav nav-tabs'>
    <li class='active'><a href='#home'>Home</a></li>
    <li><a href='#menu1'>Menu 1</a></li>
    <li><a href='#menu2'>Menu 2</a></li>
    <li><a href='#menu3'>Menu 3</a></li>
  </ul>

  <div class='tab-content'>
    <div id='home' class='tab-pane fade in active'>
      <h3>HOME</h3>
    <div id='menu1' class='tab-pane fade'>
      <h3>Menu 1</h3>
    </div>
    <div id='menu2' class='tab-pane fade'>
      <h3>Menu 2</h3>
    </div>
    <div id='menu3' class='tab-pane fade'>
      <h3>Menu 3</h3>
    </div>
  </div>
</div>

<script>
$(document).ready(function(){
// Handling data-toggle manually
    $('.nav-tabs a').click(function(){
        $(this).tab('show');
    });
// The on tab shown event
    $('.nav-tabs a').on('shown.bs.tab', function (e) {
        alert('Hello from the other siiiiiide!');
        var current_tab = e.target;
        var previous_tab = e.relatedTarget;
    });
});
</script>

It's true that including the class in application-context.xml avoids the need to use getBean. However, even that is actually unnecessary. If you are writing a standalone application and you DON'T want to include your driver class in application-context.xml, you can use the following code to have Spring autowire the driver's dependencies:

public class AutowireThisDriver {

    private MySpringBean mySpringBean;    

    public static void main(String[] args) {
       AutowireThisDriver atd = new AutowireThisDriver(); //get instance

       ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext(
                  "/WEB-INF/applicationContext.xml"); //get Spring context 

       //the magic: auto-wire the instance with all its dependencies:
       ctx.getAutowireCapableBeanFactory().autowireBeanProperties(atd,
                  AutowireCapableBeanFactory.AUTOWIRE_BY_TYPE, true);        

       // code that uses mySpringBean ...
       mySpringBean.doStuff() // no need to instantiate - thanks to Spring
    }

    public void setMySpringBean(MySpringBean bean) {
       this.mySpringBean = bean;    
    }
}

I've needed to do this a couple of times when I have some sort of standalone class that needs to use some aspect of my app (eg for testing) but I don't want to include it in application-context because it is not actually part of the app. Note also that this avoids the need to look up the bean using a String name, which I've always thought was ugly.

The key elements include:

1. the class="nav nav-tabs" and data-tabs="tabs" of ul
2. the data-toggle="tab" and href="#orange" of the a
3. the class="tab-content" of the div of the content
4. the class="tab-pane" and id of the div of the items

The complete code is as below:

<ul class="nav nav-tabs" data-tabs="tabs">
    <li class="active"><a data-toggle="tab" href="#red">Red</a></li>
    <li><a data-toggle="tab" href="#orange">Orange</a></li>
    <li><a data-toggle="tab" href="#yellow">Yellow</a></li>
    <li><a data-toggle="tab" href="#green">Green</a></li>
    <li><a data-toggle="tab" href="#blue">Blue</a></li>
</ul>
<div class="tab-content">
    <div class="tab-pane active" id="red">
        <h1>Red</h1>
        <p>red red red red red red</p>
    </div>
    <div class="tab-pane" id="orange">
        <h1>Orange</h1>
        <p>orange orange orange orange orange</p>
    </div>
    <div class="tab-pane" id="yellow">
        <h1>Yellow</h1>
        <p>yellow yellow yellow yellow yellow</p>
    </div>
    <div class="tab-pane" id="green">
        <h1>Green</h1>
        <p>green green green green green</p>
    </div>
    <div class="tab-pane" id="blue">
        <h1>Blue</h1>
        <p>blue blue blue blue blue</p>
    </div>
</div>

C is meant to be a step above assembly language. The C if-statement is really just syntactical sugar for "branch-if-zero", so the idea of booleans as an independent datatype was a foreign concept at the time. (1)

Even now, C/C++ booleans are usually little more than an alias for a single byte data type. As such, it's really more of a purposing label than an independent datatype.

(1) Of course, modern compilers are a bit more advanced in their handling of if statements. This is from the standpoint of C as a new language.

Can't comment on accepted answer so I'll add some comments here:

• I second Brad on schemas issue. From MS reference sys.objects table contains only schema-scoped objects. So to get info about "higher level" objects (i.e. schemas in our case) you need to use sys.schemas table.
• For [ObjectType] it's better to use obj.type_desc only for OBJECT_OR_COLUMN permission class. For all other cases use perm.[class_desc]
• Another type of permission which is not handled so well with this query is IMPERSONATE. To get info about impersonations one should LEFT JOIN with sys.database_principals on perm.major_id = imp.principal_id
• With my experience it's better to replace sys.login_token with sys.server_principals as it will show also SQL Logins, not only Windows ones
• One should add 'G' to allowed principal types to allow Windows groups
• Also, one can exclude users sys and INFORMATION_SCHEMA from resulting table, as these users are used only for service

I'll post first piece of script with all proposed fixes, other parts should be changed as well:

SELECT  
    [UserName] = ulogin.[name],
    [UserType] = CASE princ.[type]
                    WHEN 'S' THEN 'SQL User'
                    WHEN 'U' THEN 'Windows User'
                    WHEN 'G' THEN 'Windows Group'

    [Role] = null,      
    [PermissionType] = perm.[permission_name],       
    [PermissionState] = perm.[state_desc],       
    [ObjectType] = CASE perm.[class] 
                        WHEN 1 THEN obj.type_desc               -- Schema-contained objects
                        ELSE perm.[class_desc]                  -- Higher-level objects
                   END,       
    [ObjectName] = CASE perm.[class]

                        WHEN 4 THEN imp.[name]                  -- Impersonations

The fastest and simplest way is by setting the .length property to the desired length:

arr.length = 4;

This is also the desired way to reset/empty arrays:

arr.length = 0;

Caveat: setting this property can also make the array longer than it is: If its length is 2, running arr.length = 4 will add two undefined items to it. Perhaps add a condition:

if (arr.length > 4) arr.length = 4;

Alternatively:

arr.length = Math.min(arr.length, 4);

[Update: 2014-11-26] As Yar summarizes nicely below, before you do anything, make sure you know the URL of the submodule. If unknown, open .git/.gitmodules and examine the keysubmodule.<name>.url.

What worked for me was to remove the old submodule using git submodule deinit <submodule> followed by git rm <submodule-folder>. Then add the submodule again with the new folder name and commit. Checking git status before committing shows the old submodule renamed to the new name and .gitmodule modified.

$ git submodule deinit foo
$ git rm foo
$ git submodule add https://bar.com/foo.git new-foo
$ git status
renamed:    foo -> new-foo
modified:   .gitmodules
$ git commit -am "rename foo submodule to new-foo"

I use javascript encodeURI() function for the URL part that has forward slashes that should be seen as characters instead of http address. Eg:

"/api/activites/" + encodeURI("?categorie=assemblage&nom=Manipulation/Finition")

see http://www.w3schools.com/tags/ref_urlencode.asp

• nchar is fixed-length and can hold unicode characters. it uses two bytes storage per character.

• varchar is of variable length and cannot hold unicode characters. it uses one byte storage per character.

I had a related problem with rJava. It would load but a package that depends on it, would not load.

Users may waste a lot of time with jvm.dll and PATH and JAVA_HOME when the real fix is to force the installer to just forget about i386. Use option for install.packages. (this also works when drat library is used. (credit goes to Dason)

install.packages("SqlRender",INSTALL_opts="--no-multiarch")

Also, you can modify just your user path with a win command like this:

setx PATH "C:\Program Files\Java\jre1.8.0_102\bin\server;%PATH%"

The classes LocalDate and LocalDateTime do not contain information about the timezone or time offset, and seconds since epoch would be ambigious without this information. However, the objects have several methods to convert them into date/time objects with timezones by passing a ZoneId instance.

LocalDate

LocalDate date = ...;
ZoneId zoneId = ZoneId.systemDefault(); // or: ZoneId.of("Europe/Oslo");
long epoch = date.atStartOfDay(zoneId).toEpochSecond();

LocalDateTime

LocalDateTime time = ...;
ZoneId zoneId = ZoneId.systemDefault(); // or: ZoneId.of("Europe/Oslo");
long epoch = time.atZone(zoneId).toEpochSecond();

Mssql Authentication is highly preferable where possible. It allows you to conform with an existing windows domain already used at your workplace, and you don't have to know your user's passwords.

However, It seems that it would not be possible for use in the occasion that the server's machine does not authenticate to your local workplace's intranet.

If you use sql authentication, security will be entirely up to you.

If you use microsoft authentication, security is essentially taken care of for you, but you'll be dealing with additional restrictions.

You need to compile the bibtex file.

Suppose you have article.tex and article.bib. You need to run:

• latex article.tex (this will generate a document with question marks in place of unknown references)
• bibtex article (this will parse all the .bib files that were included in the article and generate metainformation regarding references)
• latex article.tex (this will generate document with all the references in the correct places)
• latex article.tex (just in case if adding references broke page numbering somewhere)

You can also do this to set a header for all future gets for the Session object, where x-test will be in all s.get() calls:

s = requests.Session()
s.auth = ('user', 'pass')
s.headers.update({'x-test': 'true'})

# both 'x-test' and 'x-test2' are sent
s.get('http://httpbin.org/headers', headers={'x-test2': 'true'})

Swift 5

I used "actionsheet" style for iPhone and "alert" for iPad. iPad displays in the center of the screen. No need to specify sourceView or anchor the view anywhere.

var alertStyle = UIAlertController.Style.actionSheet
if (UIDevice.current.userInterfaceIdiom == .pad) {
  alertStyle = UIAlertController.Style.alert
}

let alertController = UIAlertController(title: "Your title", message: nil, preferredStyle: alertStyle)

Edit: Per ShareToD's suggestion, updated deprecated "UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.pad" check

Try this. Here is the code to get the sheet names in order.

private Dictionary<int, string> GetExcelSheetNames(string fileName)
{
    Excel.Application _excel = null;
    Excel.Workbook _workBook = null;
    Dictionary<int, string> excelSheets = new Dictionary<int, string>();
    try
    {
        object missing = Type.Missing;
        object readOnly = true;
        Excel.XlFileFormat.xlWorkbookNormal
        _excel = new Excel.ApplicationClass();
        _excel.Visible = false;
        _workBook = _excel.Workbooks.Open(fileName, 0, readOnly, 5, missing,
            missing, true, Excel.XlPlatform.xlWindows, "\\t", false, false, 0, true, true, missing);
        if (_workBook != null)
        {
            int index = 0;
            foreach (Excel.Worksheet sheet in _workBook.Sheets)
            {
                // Can get sheet names in order they are in workbook
                excelSheets.Add(++index, sheet.Name);
            }
        }
    }
    catch (Exception e)
    {
        return null;
    }
    finally
    {
        if (_excel != null)
        {

            if (_workBook != null)
                _workBook.Close(false, Type.Missing, Type.Missing);
            _excel.Application.Quit();
        }
        _excel = null;
        _workBook = null;
    }
    return excelSheets;
}

I would suggest the following:

String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName); 

You just need to add disabled as option attribute

<option disabled>select one option</option>

Sounds like the instance was launched in VPC and while doing so, the check-box for Automatically assign a public IP address to your instances was not checked. Hence the instance does not have a public IP

You can assign an Elastic IP to this instance and then log in using that IP.

I second Hightechrider: there is a specialized Url class already built for you.

I must also point out, however, that the PHP's replaceAll uses regular expressions for search pattern, which you can do in .NET as well - look at the RegEx class.

Since jQuery 1.5 you can use the deferred objects mechanism:

$.post('some.php', {name: 'John'})
    .done(function(msg){  })
    .fail(function(xhr, status, error) {
        // error handling
    });

Another way is using .ajax:

$.ajax({
  type: "POST",
  url: "some.php",
  data: "name=John&location=Boston",
  success: function(msg){
        alert( "Data Saved: " + msg );
  },
  error: function(XMLHttpRequest, textStatus, errorThrown) {
     alert("some error");
  }
});

sumall = summ + sumd + sumy

Your sumall is an integer. If you want the individual characters from it, convert it to a string first.

Try something like this it will help you

$("#from").click(function () {
           $('#from').attr('readonly', true);
     });

Thanks

You want the Dictionary class.

These are exactly the same. android:onClick was added in API level 4 to make it easier, more Javascript-web-like, and drive everything from the XML. What it does internally is add an OnClickListener on the Button, which calls your DoIt method.

Here is what using a android:onClick="DoIt" does internally:

Button button= (Button) findViewById(R.id.buttonId);
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        DoIt(v);
    }
});

The only thing you trade off by using android:onClick, as usual with XML configuration, is that it becomes a bit more difficult to add dynamic content (programatically, you could decide to add one listener or another depending on your variables). But this is easily defeated by adding your test within the DoIt method.

.html() only takes a string OR a function as an argument, not both. Try this:

 $("#showDiv").click(function () {
     $('#theDiv').show(1000, function () {
         setTimeout(function () {
             $('#theDiv').html(function () {
                 setTimeout(function () {
                     $('#theDiv').html('Here is some replacement text');
                 }, 0);
                 setTimeout(function () {
                     $('#theDiv').html('More replacement text goes here');
                 }, 2500);
             });
         }, 2500);
     });
 }); //click function ends

A modern approach is to use ASP.NET Web API 2 (server-side) with jQuery Ajax (client-side).

Like page methods and ASMX web methods, Web API allows you to write C# code in ASP.NET which can be called from a browser or from anywhere, really!

Here is an example Web API controller, which exposes API methods allowing clients to retrieve details about 1 or all products (in the real world, products would likely be loaded from a database):

public class ProductsController : ApiController
{
    Product[] products = new Product[] 
    { 
        new Product { Id = 1, Name = "Tomato Soup", Category = "Groceries", Price = 1 }, 
        new Product { Id = 2, Name = "Yo-yo", Category = "Toys", Price = 3.75M }, 
        new Product { Id = 3, Name = "Hammer", Category = "Hardware", Price = 16.99M } 
    };

    [Route("api/products")]
    [HttpGet]
    public IEnumerable<Product> GetAllProducts()
    {
        return products;
    }

    [Route("api/product/{id}")]
    [HttpGet]
    public IHttpActionResult GetProduct(int id)
    {
        var product = products.FirstOrDefault((p) => p.Id == id);
        if (product == null)
        {
            return NotFound();
        }
        return Ok(product);
    }
}

The controller uses this example model class:

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Category { get; set; }
    public decimal Price { get; set; }
}

Example jQuery Ajax call to get and iterate over a list of products:

$(document).ready(function () {
    // Send an AJAX request
    $.getJSON("/api/products")
        .done(function (data) {
            // On success, 'data' contains a list of products.
            $.each(data, function (key, item) {
                // Add a list item for the product.
                $('<li>', { text: formatItem(item) }).appendTo($('#products'));
            });
        });
});

Not only does this allow you to easily create a modern Web API, you can if you need to get really professional and document it too, using ASP.NET Web API Help Pages and/or Swashbuckle.

Web API can be retro-fitted (added) to an existing ASP.NET Web Forms project. In that case you will need to add routing instructions into the Application_Start method in the file Global.asax:

RouteTable.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = System.Web.Http.RouteParameter.Optional }
);

numpy has a great tool for this task ("numpy.reshape") link to reshape documentation

a = [[ 0  1]
 [ 2  3]
 [ 4  5]
 [ 6  7]
 [ 8  9]
 [10 11]
 [12 13]
 [14 15]
 [16 17]]

`numpy.reshape(a,(3,3))`

you can also use the "-1" trick

`a = a.reshape(-1,3)`

the "-1" is a wild card that will let the numpy algorithm decide on the number to input when the second dimension is 3

so yes.. this would also work: a = a.reshape(3,-1)

and this: a = a.reshape(-1,2) would do nothing

and this: a = a.reshape(-1,9) would change the shape to (2,9)

In the case you are asking about, this represents the HTML DOM element.

So it would be the <a> element that was clicked on.

Hashmaps can only use classes, not primitives. This page from programmerinterview.com might be of use in guiding you to finding the answer. To be honest, I haven't figured out the answer to this problem in detail myself.

Open up a command prompt then type...

netstat -a

I faced the same error and did some research to only see that there could be different scenarios to this error. Let me share my findings.

Scenario 1: There cannot be spaces beside the = (equals) sign

$ export TEMP_ENV = example-value
-bash: export: `=': not a valid identifier
// this is the answer to the question

$ export TEMP_ENV =example-value
-bash: export: `=example-value': not a valid identifier

$ export TEMP_ENV= example-value
-bash: export: `example-value': not a valid identifier

Scenario 2: Object value assignment should not have spaces besides quotes

$ export TEMP_ENV={ "key" : "json example" } 
-bash: export: `:': not a valid identifier
-bash: export: `json example': not a valid identifier
-bash: export: `}': not a valid identifier

Scenario 3: List value assignment should not have spaces between values

$ export TEMP_ENV=[1,2 ,3 ]
-bash: export: `,3': not a valid identifier
-bash: export: `]': not a valid identifier

I'm sharing these, because I was stuck for a couple of hours trying to figure out a workaround. Hopefully, it will help someone in need.

In Command prompt go to project folder and execute following:

ng g s servicename

Let's try to keep it simple and discuss how it is actually working. It has to do with variable types and function parameters.

Here is your code we are talking about:

var arr = ["one","two","three"];

arr.forEach(function(part) {
  part = "four";
  return "four";
})

alert(arr);

First off, here is where you should be reading about Array.prototype.forEach():

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach

Second, let's talk briefly about value types in JavaScript.

Primitives (undefined, null, String, Boolean, Number) store an actual value.

ex: var x = 5;

Reference Types (custom objects) store the memory location of the object.

ex: var xObj = { x : 5 };

And third, how function parameters work.

In functions, parameters are always passed by value.

Because arr is an array of Strings, it's an array of primitive objects, which means they are stored by value.

So for your code above, this means that each time the forEach() iterates, part is equal to the same value as arr[index], but not the same object.

part = "four"; will change the part variable, but will leave arr alone.

The following code will change the values you desire:

var arr = ["one","two","three"];

arr.forEach(function(part, index) {
  arr[index] = "four";
});

alert(arr);

Now if array arr was an array of reference types, the following code will work because reference types store a memory location of an object instead of the actual object.

var arr = [{ num : "one" }, { num : "two"}, { num : "three"}];

arr.forEach(function(part, index) {
  // part and arr[index] point to the same object
  // so changing the object that part points to changes the object that arr[index] points to

  part.num = "four";
});

alert(arr[0].num);
alert(arr[1].num);
alert(arr[2].num);

The following illustrates that you can change part to point to a new object while leaving the objects stored in arr alone:

var arr = [{ num : "one" }, { num : "two"}, { num : "three"}];

arr.forEach(function(part, index) {
  // the following will not change the object that arr[index] points to because part now points at a new object
  part = 5;
});

alert(arr[0].num);
alert(arr[1].num);
alert(arr[2].num);

Better solution for different currency formats:

def text_currency_to_float(text):
  t = text
  dot_pos = t.rfind('.')
  comma_pos = t.rfind(',')
  if comma_pos > dot_pos:
    t = t.replace(".", "")
    t = t.replace(",", ".")
  else:
    t = t.replace(",", "")

  return(float(t))

This question is the first one that shows up on Google when one looks up "Python how to add elements to set", so it's worth noting explicitly that, if you want to add a whole string to a set, it should be added with .add(), not .update().

Say you have a string foo_str whose contents are 'this is a sentence', and you have some set bar_set equal to set().

If you do bar_set.update(foo_str), the contents of your set will be {'t', 'a', ' ', 'e', 's', 'n', 'h', 'c', 'i'}.

If you do bar_set.add(foo_str), the contents of your set will be {'this is a sentence'}.

In python there is no difference between modules and scripts; You can execute both scripts and modules. The file must be on the pythonpath AFAIK because python must be able to find the file in question. If python is executed from a directory, then the directory is automatically added to the pythonpath.

Refer to What is the best way to call a Python script from another Python script? for more information about modules vs scripts

There is also a builtin function execfile(filename) that will do what you want

The get property works great, and you can also use a binded closure for "expensive" functions that should only run once (this only works with var, not with const or let)

var info = {
  address: (function() {
    return databaseLookup(this.id)
  }).bind(info)(),

  get fullName() {
    console.log('computing fullName...')
    return `${this.first} ${this.last}`
  },

  id: '555-22-9999',
  first: 'First',
  last: 'Last',
}

function databaseLookup() {
  console.log('fetching address from remote server (runs once)...')
  return Promise.resolve(`22 Main St, City, Country`)
}

// test
(async () => {
  console.log(info.fullName)
  console.log(info.fullName)
  console.log(await info.address)
  console.log(await info.address)
  console.log(await info.address)
  console.log(await info.address)
})()

From that error, I would say that your code is fine, at least the part that calls the webservice. The error seems to be in the actual web service.

To get the error from the web server, add a try catch and catch a WebException. A WebException has a property called Response which is a HttpResponse. you can then log anything that is returned, and upload you code. Check back later in the logs and see what is actually being returned.

Please check the UTM coordinate system https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system.

These values must be in meters for a specific map projection. For example, the peak of Mount Assiniboine (at 50°52'10"N 115°39'03"W) in UTM Zone 11 is represented by 11U 594934.108296 5636174.091274 where (594934.108296, 5636174.091274) are in meters.

Use Range("A1").Text instead of .Value

post comment edit:
Why?
Because the .Text property of Range object returns what is literally visible in the spreadsheet, so if you cell displays for example i100l:25he*_92 then <- Text will return exactly what it in the cell including any formatting.
The .Value and .Value2 properties return what's stored in the cell under the hood excluding formatting. Specially .Value2 for date types, it will return the decimal representation.

If you want to dig deeper into the meaning and performance, I just found this article which seems like a good guide

another edit
Here you go @Santosh
type in (MANUALLY) the values from the DEFAULT (col A) to other columns
Do not format column A at all
Format column B as Text
Format column C as Date[dd/mm/yyyy]
Format column D as Percentage

now,
paste this code in a module

Sub main()

    Dim ws As Worksheet, i&, j&
    Set ws = Sheets(1)
    For i = 3 To 7
        For j = 1 To 4
            Debug.Print _
                    "row " & i & vbTab & vbTab & _
                    Cells(i, j).Text & vbTab & _
                    Cells(i, j).Value & vbTab & _
                    Cells(i, j).Value2
        Next j
    Next i
End Sub

and Analyse the output! Its really easy and there isn't much more i can do to help :)

One alternative would be to parse with yq (https://github.com/kislyuk/yq) like so:

cat pom.xml | xq -r '.project.version'

Notice the executable is xq not yq

To get xq, install yq like so pip install yq

If the folder just contains functions then adding the folders to the path at the start of the script will suffice.

addpath('../folder_x/');
addpath('../folder_y/');

If they are Packages, folders starting with a '+' then they also need to be imported.

import package_x.*
import package_y.*

You need to add the package folders parent to the search path.

As per the latest documentation, the correct method to call would be:

Reporter.objects.all().delete()

Are you tied to this library? Google Gson is very popular. I have myself not used it with Generics but their front page says Gson considers support for Generics very important.

You can do it with a LINQ like solution instead of a regular expression:

string input = "123- abcd33";
string chars = new String(input.Where(c => c != '-' && (c < '0' || c > '9')).ToArray());

A quick performance test shows that this is about five times faster than using a regular expression.

This is what I ended up with:

function WhoLikesCake(options) {
  options = options || {};
  var defaultOptions = {
    a : options.a || "Huh?",
    b : options.b || "I don't like cake."
  }
  console.log('a: ' + defaultOptions.b + ' - b: ' + defaultOptions.b);

  // Do more stuff here ...
}

Called like this:

WhoLikesCake({ b : "I do" });

As mentioned by Alejandro Corredor it is a simple scope error. The subscribe is run asynchronously and the open must be placed in that context, so that the data finished loading when we trigger the download.

That said, there are two ways of doing it. As the docs recommend the service takes care of getting and mapping the data:

//On the service:
downloadfile(runname: string, type: string){
  var headers = new Headers();
  headers.append('responseType', 'arraybuffer');
  return this.authHttp.get( this.files_api + this.title +"/"+ runname + "/?file="+ type)
            .map(res => new Blob([res],{ type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' }))
            .catch(this.logAndPassOn);
}

Then, on the component we just subscribe and deal with the mapped data. There are two possibilities. The first, as suggested in the original post, but needs a small correction as noted by Alejandro:

//On the component
downloadfile(type: string){
  this.pservice.downloadfile(this.rundata.name, type)
      .subscribe(data => window.open(window.URL.createObjectURL(data)),
                  error => console.log("Error downloading the file."),
                  () => console.log('Completed file download.'));
  }

The second way would be to use FileReader. The logic is the same but we can explicitly wait for FileReader to load the data, avoiding the nesting, and solving the async problem.

//On the component using FileReader
downloadfile(type: string){
    var reader = new FileReader();
    this.pservice.downloadfile(this.rundata.name, type)
        .subscribe(res => reader.readAsDataURL(res), 
                    error => console.log("Error downloading the file."),
                    () => console.log('Completed file download.'));

    reader.onloadend = function (e) {
        window.open(reader.result, 'Excel', 'width=20,height=10,toolbar=0,menubar=0,scrollbars=no');
  }
}

Note: I am trying to download an Excel file, and even though the download is triggered (so this answers the question), the file is corrupt. See the answer to this post for avoiding the corrupt file.

Use This as the solution

This worked for me perfectly..

Easy Java 9 solution with try with resources block

public static void copyInputStreamToFile(InputStream input, File file) {  

    try (OutputStream output = new FileOutputStream(file)) {
        input.transferTo(output);
    } catch (IOException ioException) {
        ioException.printStackTrace();
    }

java.io.InputStream#transferTo is available since Java 9.

On rooted device you can do this:

1. Open cmd
2. Type adb shell
3. su
4. Press 'Allow' on device
5. chmod 777 /data /data/data /data/data/com.application.package/data/data/com.application.package/*
6. Go to the DDMS view in Eclipse

After this you should be able to browse the files on the device.

To get the databases:

7. chmod 777 /data/data/com.application.package/databases /data/data/com.application.package/databases/*

If it returns permission denied on su

Go to Settings > Developer Options > Root access > Apps and ADB

To create a label for text:

JLabel label1 = new JLabel("Test");

To change the text in the label:

label1.setText("Label Text");

And finally to clear the label:

label1.setText("");

And all you have to do is place the label in your layout, or whatever layout system you are using, and then just add it to the JFrame...

Open package.json and look under dependencies. You should see:

  "dependencies": {
    ...
    "bootstrap-less": "^3.8.8"
    ...
    }

for angular 5 and over

It's limited in that you can't put statements in there. You can only put values(or things that return/evaluate to values), to return

This works ('a' is a static int within class Blah)

Blah.a=Blah.a<5?1:8;

(round brackets are impicitly between the equals and the question mark).

This doesn't work.

Blah.a = Blah.a < 4 ? Console.WriteLine("asdf") : Console.WriteLine("34er");
or
Blah.a = Blah.a < 4 ? MessageBox.Show("asdf") : MessageBox.Show("34er");

So you can only use the c# ternary operator for returning values. So it's not quite like a shortened form of an if. Javascript and perhaps some other languages let you put statements in there.

In case someone else runs accross this and wants to just disable all path variable changing for all users.
Access your sudoers file by using the command:visudo. You should see the following line somewhere:

Defaults env_reset

which you should add the following on the next line

Defaults !secure_path

secure_path is enabled by default. This option specifies what to make $PATH when sudoing. The exclamation mark disables the feature.

Just use this website: http://ticons.fokkezb.nl :)

It makes it easier for you, and generates the correct sizes directly

I had approximately the same problem with Laravel 5.5 on ubuntu, finally i've found a solution here to switch between the versions of php used by apache :

1. sudo a2dismod php5
2. sudo a2enmod php7.1
3. sudo service apache2 restart

and it works

When most people talk about binary trees, they're more often than not thinking about binary search trees, so I'll cover that first.

A non-balanced binary search tree is actually useful for little more than educating students about data structures. That's because, unless the data is coming in in a relatively random order, the tree can easily degenerate into its worst-case form, which is a linked list, since simple binary trees are not balanced.

A good case in point: I once had to fix some software which loaded its data into a binary tree for manipulation and searching. It wrote the data out in sorted form:

Alice
Bob
Chloe
David
Edwina
Frank

so that, when reading it back in, ended up with the following tree:

  Alice
 /     \
=       Bob
       /   \
      =     Chloe
           /     \
          =       David
                 /     \
                =       Edwina
                       /      \
                      =        Frank
                              /     \
                             =       =

which is the degenerate form. If you go looking for Frank in that tree, you'll have to search all six nodes before you find him.

Binary trees become truly useful for searching when you balance them. This involves rotating sub-trees through their root node so that the height difference between any two sub-trees is less than or equal to 1. Adding those names above one at a time into a balanced tree would give you the following sequence:

1.   Alice
    /     \
   =       =

2.   Alice
    /     \
   =       Bob
          /   \
         =     =

3.        Bob
        _/   \_
   Alice       Chloe
  /     \     /     \
 =       =   =       =

4.        Bob
        _/   \_
   Alice       Chloe
  /     \     /     \
 =       =   =       David
                    /     \
                   =       =

5.           Bob
        ____/   \____
   Alice             David
  /     \           /     \
 =       =     Chloe       Edwina
              /     \     /      \
             =       =   =        =

6.              Chloe
            ___/     \___
         Bob             Edwina
        /   \           /      \
   Alice     =      David        Frank
  /     \          /     \      /     \
 =       =        =       =    =       =

You can actually see whole sub-trees rotating to the left (in steps 3 and 6) as the entries are added and this gives you a balanced binary tree in which the worst case lookup is O(log N) rather than the O(N) that the degenerate form gives. At no point does the highest NULL (=) differ from the lowest by more than one level. And, in the final tree above, you can find Frank by only looking at three nodes (Chloe, Edwina and, finally, Frank).

Of course, they can become even more useful when you make them balanced multi-way trees rather than binary trees. That means that each node holds more than one item (technically, they hold N items and N+1 pointers, a binary tree being a special case of a 1-way multi-way tree, with 1 item and 2 pointers).

With a three-way tree, you end up with:

  Alice Bob Chloe
 /     |   |     \
=      =   =      David Edwina Frank
                 /     |      |     \
                =      =      =      =

This is typically used in maintaining keys for an index of items. I've written database software optimised for the hardware where a node is exactly the size of a disk block (say, 512 bytes) and you put as many keys as you can into a single node. The pointers in this case were actually record numbers into a fixed-length-record direct-access file separate from the index file (so record number X could be found by just seeking to X * record_length).

For example, if the pointers are 4 bytes and the key size is 10, the number of keys in a 512-byte node is 36. That's 36 keys (360 bytes) and 37 pointers (148 bytes) for a total of 508 bytes with 4 bytes wasted per node.

The use of multi-way keys introduces the complexity of a two-phase search (multi-way search to find the correct node combined with a small sequential (or linear binary) search to find the correct key in the node) but the advantage in doing less disk I/O more than makes up for this.

I see no reason to do this for an in-memory structure, you'd be better off sticking with a balanced binary tree and keeping your code simple.

Also keep in mind that the advantages of O(log N) over O(N) don't really appear when your data sets are small. If you're using a multi-way tree to store the fifteen people in your address book, it's probably overkill. The advantages come when you're storing something like every order from your hundred thousand customers over the last ten years.

The whole point of big-O notation is to indicate what happens as the N approaches infinity. Some people may disagree but it's even okay to use bubble sort if you're sure the data sets will stay below a certain size, as long as nothing else is readily available :-)

As to other uses for binary trees, there are a great many, such as:

• Binary heaps where higher keys are above or equal to lower ones rather than to the left of (or below or equal to and right);
• Hash trees, similar to hash tables;
• Abstract syntax trees for compilation of computer languages;
• Huffman trees for compression of data;
• Routing trees for network traffic.

Given how much explanation I generated for the search trees, I'm reticent to go into a lot of detail on the others, but that should be enough to research them, should you desire.

You just need to toggle the value of "isReplyFormOpen" on ng-click event

<a ng-click="isReplyFormOpen = !isReplyFormOpen">Reply</a>
 <div ng-show="isReplyFormOpen" id="replyForm">
   </div>

This is my personal understanding about the topic.

For a project, we can do the version control by different repositories. And for a repository, it can manage a whole project or part of projects.

Regarding on your project (several prototype applications which are independent of each them). You can manage the project by one repository or by several repositories, the difference:

1. Manage by one repository. If one of the applications is changed, the whole project (all the applications) will be committed to a new version.

2. Manage by several repositories. If one application is changed, it will only affect the repository which manages the application. Version for other repositories was not changed.

Don't use @@ERROR, use BEGIN TRY/BEGIN CATCH instead. See this article: Exception handling and nested transactions for a sample procedure:

create procedure [usp_my_procedure_name]
as
begin
    set nocount on;
    declare @trancount int;
    set @trancount = @@trancount;
    begin try
        if @trancount = 0
            begin transaction
        else
            save transaction usp_my_procedure_name;

        -- Do the actual work here

lbexit:
        if @trancount = 0   
            commit;
    end try
    begin catch
        declare @error int, @message varchar(4000), @xstate int;
        select @error = ERROR_NUMBER(), @message = ERROR_MESSAGE(), @xstate = XACT_STATE();
        if @xstate = -1
            rollback;
        if @xstate = 1 and @trancount = 0
            rollback
        if @xstate = 1 and @trancount > 0
            rollback transaction usp_my_procedure_name;

        raiserror ('usp_my_procedure_name: %d: %s', 16, 1, @error, @message) ;
        return;
    end catch   
end

First replicate the location and styling of the text and then use Jquery width() function. This will make the measurements accurate. For example you have css styling with a selector of:

.style-head span
{
  //Some style set
}

You would need to do this with Jquery already included above this script:

var measuringSpan = document.createElement("span");
measuringSpan.innerText = 'text to measure';
measuringSpan.style.display = 'none'; /*so you don't show that you are measuring*/
$('.style-head')[0].appendChild(measuringSpan);
var theWidthYouWant = $(measuringSpan).width();

Needless to say

theWidthYouWant

will hold the pixel length. Then remove the created elements after you are done or you will get several if this is done a several times. Or add an ID to reference instead.

add this

owl.trigger('owl.play',6000);

Cron is so named "deamon" (same as service under Win).

Most likely cron is already installed on your system (if it is a Linux/Unix system).

Look here: http://www.comptechdoc.org/os/linux/startupman/linux_sucron.html

or there http://en.wikipedia.org/wiki/Cron

for more details.

If anyone has this issue when building a Maven project created in IntelliJ IDEA externally, I used the following dependency instead of the answer:

<dependency>
  <groupId>org.jetbrains</groupId>
  <artifactId>annotations</artifactId>
  <version>15.0</version>
</dependency>

Using this will allow the project to build on IntelliJ IDEA and by itself using Maven.

You can find it here.

You can run the pipenv command with the --rm option as in:

pipenv --rm

This will remove the virtualenv created for you under ~/.virtualenvs

See https://pipenv.kennethreitz.org/en/latest/cli/#cmdoption-pipenv-rm

I solved in this way: I logged in with root username

mysql -u root -p -h localhost

I created a new user with

CREATE USER 'francesco'@'localhost' IDENTIFIED BY 'some_pass';

then I created the database

CREATE DATABASE shop;

I granted privileges for new user for this database

GRANT ALL PRIVILEGES ON shop.* TO 'francesco'@'localhost';

Then I logged out root and logged in new user

quit;
mysql -u francesco -p -h localhost

I rebuilt my database using a script

source shop.sql;

And that's it.. Now from php works without problems with the call

 $conn = new mysqli("localhost", "francesco", "some_pass", "shop");

Thanks to all for your time :)

My data was just json data string . (This variable was stored as json string in the session).

console.log(json_string_object)

-> returns just the representation of this string and there is no way to make difference whether is string or object.

So to make it work I just needed to convert it back to real object:

object = JSON.parse(json_string_object);

That Exception is thrown if there is already a key in the dictionary when you try to add the new one.

There must be more than one line in rct3Lines with the same first word. You can't have 2 entries in the same dictionary with the same key.

You need to decide what you want to happen if the key already exists - if you want to just update the value where the key exists you can simply

rct3Features[items[0]]=items[1]

but, if not you may want to test if the key already exists with:

if(rect3Features.ContainsKey(items[0]))
{
    //Do something
} 
else 
{
    //Do something else
}

I faced the same problem and quoting the , did not help. Eventually, I replaced the , with +, finished the processing, saved the output into an outfile and replaced the + with ,. This may seem ugly but it worked for me.

Although many correct answers have already been given, the classical (read non-DOM) approach would be like this:

document.forms['yourform']['yourtextarea'].value = 'yourvalue';

where in the HTML your textarea is nested somewhere in a form like this:

<form name="yourform">
    <textarea name="yourtextarea" rows="10" cols="60"></textarea>
</form>

And as it happens, that would work with Netscape Navigator 4 and Internet Explorer 3 too. And, not unimportant, Internet Explorer on mobile devices.

There is the semicolon missing (;) after the "50%"

but you should also notice that the percentage of your div is connected to the div that contains it.

for instance:

<div id="wrapper">
  <div class="container">
   adsf
  </div>
</div>

#wrapper {
  height:100px;
}
.container
{
  width:80%;
  height:50%;
  background-color:#eee;
}

here the height of your .container will be 50px. it will be 50% of the 100px from the wrapper div.

if you have:

adsf

#wrapper {
  height:400px;
}
.container
{
  width:80%;
  height:50%;
  background-color:#eee;
}

then you .container will be 200px. 50% of the wrapper.

So you may want to look at the divs "wrapping" your ".container"...

You should consider have other php files included if you're going to derive a website from it. Instead of doing all the css/etc in that file, you can do

<head>
    <?php include_once('C:\Users\George\Documents\HTML\style.css'); ?>
    <title>Title</title>
</hea>

Then you can have a separate CSS file that is just being pulled into your php file. It provides some "neater" coding.

You can see a difference between the two contexts when you launch your app directly from the home screen vs when your app is launched from another app via share intent.

Here a practical example of what "non-standard back stack behaviors", mentioned by @CommonSenseCode, means:

Suppose that you have two apps that communicate with each other, App1 and App2.

Launch App2:MainActivity from launcher. Then from MainActivity launch App2:SecondaryActivity. There, either using activity context or application context, both activities live in the same task and this is ok (given that you use all standard launch modes and intent flags). You can go back to MainActivity with a back press and in the recent apps you have only one task.

Suppose now that you are in App1 and launch App2:MainActivity with a share intent (ACTION_SEND or ACTION_SEND_MULTIPLE). Then from there try to launch App2:SecondaryActivity (always with all standard launch modes and intent flags). What happens is:

• if you launch App2:SecondaryActivity with application context on Android < 10 you cannot launch all the activities in the same task. I have tried with android 7 and 8 and the SecondaryActivity is always launched in a new task (I guess is because App2:SecondaryActivity is launched with the App2 application context but you're coming from App1 and you didn't launch the App2 application directly. Maybe under the hood android recognize that and use FLAG_ACTIVITY_NEW_TASK). This can be good or bad depending on your needs, for my application was bad.
  On Android 10 the app crashes with the message
  "Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?".
  So to make it work on Android 10 you have to use FALG_ACTIVITY_NEW_TASK and you cannot run all activities in the same task.
  As you can see the behavior is different between android versions, weird.

• if you launch App2:SecondaryActivity with activity context all goes well and you can run all the activities in the same task resulting in a linear backstack navigation.

I hope I have added some useful information

None of the posted answers worked for me, so I reinstalled pip and it worked!

sudo apt-get install python-setuptools python-dev build-essential 

sudo easy_install pip 

pip install --upgrade setuptools

(reference: http://www.saltycrane.com/blog/2010/02/how-install-pip-ubuntu/)

Here's a cross browser working function (usable for other than click handlers too):

function eventFire(el, etype){
    if (el.fireEvent) {
      el.fireEvent('on' + etype);
    } else {
      var evObj = document.createEvent('Events');
      evObj.initEvent(etype, true, false);
      el.dispatchEvent(evObj);
    }
}

The code formatting is available in Visual Studio Code through the following shortcuts:

• On Windows Shift + Alt + F
• On Mac Shift + Option + F
• On Linux Ctrl + Shift + I

Alternatively, you can find the shortcut, as well as other shortcuts, through the 'Command Palette' provided in the editor with Ctrl +Shift+ P (or Command + Shift + P on Mac), and then searching for format document.

For unsaved snippets

1. Open command palette (Win: F1 or Ctrt+Shift+P)

2. Find 'Change Language Model'

3. Select language e.g. json. By now syntax should be highlighted.

4. Format document (e.g. Open Command Palette -> 'Format Document')

Unformat

1. Select text
2. Command Palette -> Join Lines

'Show the pics'

If you are using Hibernate 3.6 you can use the code in the accepted answer (provided by Brian Deterling) with slight modification:

  CriteriaImpl c = (CriteriaImpl) criteria;
  SessionImpl s = (SessionImpl) c.getSession();
  SessionFactoryImplementor factory = (SessionFactoryImplementor) s.getSessionFactory();
  String[] implementors = factory.getImplementors(c.getEntityOrClassName());
  LoadQueryInfluencers lqis = new LoadQueryInfluencers();
  CriteriaLoader loader = new CriteriaLoader((OuterJoinLoadable) factory.getEntityPersister(implementors[0]), factory, c, implementors[0], lqis);
  Field f = OuterJoinLoader.class.getDeclaredField("sql");
  f.setAccessible(true);
  String sql = (String) f.get(loader);

All of these answers solve the problem, but I would like to contribute with a moders es6 solution that does exactly what is needed. I just hope to make someone happy with this runnable demo.

window.clickOutSide = (element, clickOutside, clickInside) => {
  document.addEventListener('click', (event) => {
    if (!element.contains(event.target)) {
      if (typeof clickInside === 'function') {
        clickOutside();
      }
    } else {
      if (typeof clickInside === 'function') {
        clickInside();
      }
    }
  });
};

window.clickOutSide(document.querySelector('.block'), () => alert('clicked outside'), () => alert('clicked inside'));

.block {
  width: 400px;
  height: 400px;
  background-color: red;
}

<div class="block"></div>

It is worth mentioning that the command works similarly on Linux:

git clone path/to/source/folder path/to/destination/folder

Yes, the sorting is different.

Items in the ORDER BY list are applied in order.
Later items only order peers left from the preceding step.

Why don't you just try?

The :: are used to dereference scopes.

const int x = 5;

namespace foo {
  const int x = 0;
}

int bar() {
  int x = 1;
  return x;
}

struct Meh {
  static const int x = 2;
}

int main() {
  std::cout << x; // => 5
  {
    int x = 4;
    std::cout << x; // => 4
    std::cout << ::x; // => 5, this one looks for x outside the current scope
  }
  std::cout << Meh::x; // => 2, use the definition of x inside the scope of Meh
  std::cout << foo::x; // => 0, use the definition of x inside foo
  std::cout << bar(); // => 1, use the definition of x inside bar (returned by bar)
}

unrelated: cout and cin are not functions, but instances of stream objects.

I don't think there is a way to ignore adding DEFINERs to the dump. But there are ways to remove them after the dump file is created.

1. Open the dump file in a text editor and replace all occurrences of DEFINER=root@localhost with an empty string ""

2. Edit the dump (or pipe the output) using perl:

   perl -p -i.bak -e "s/DEFINER=\`\w.*\`@\`\d[0-3].*[0-3]\`//g" mydatabase.sql
   

3. Pipe the output through sed:

   mysqldump ... | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > triggers_backup.sql
   

Edit:-

Note vim-airline is gaining some traction as the new vimscript option as powerline has gone python.

Seems powerline is where it is at these days:-

Normal status line

Customised status lines for other plugins (e.g. ctrlp)

Like @Gabi Purcaru mentions above, the proper way to rename and move the file is to use move_uploaded_file(). It performs some safety checks to prevent security vulnerabilities and other exploits. You'll need to sanitize the value of $_FILES['file']['name'] if you want to use it or an extension derived from it. Use pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION) to safely get the extension.

The serial port communication programs moserial or gtkterm provide an easy way to check connectivity and modify /dev/ttyUSB0 (or /dev/ttyUSB1!) settings. Even though there maybe only a single USB to RS232 adapter, the n designation /dev/ttyUSBn can and does change periodically! Both moserial and gtkterm will show what port designation is relevant in their respective pull down menus when selecting an appropriate port to use.

There are a few different ways to accomplish this, I'll outline my favourites.

Use a ToggleButton and apply a custom style to it. I suggest this because your required control is "like a toggle button" but just looks different from the default toggle button styling.

My preferred method is to define a graphic for the button in css:

.toggle-button {
  -fx-graphic: url('http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Pizza-icon.png');
}

.toggle-button:selected {
  -fx-graphic: url('http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Piece-of-cake-icon.png');
}

OR use the attached css to define a background image.

// file imagetogglebutton.css deployed in the same package as ToggleButtonImage.class
.toggle-button {
  -fx-background-image: url('http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Pizza-icon.png');
  -fx-background-repeat: no-repeat;
  -fx-background-position: center;
}

.toggle-button:selected {
  -fx-background-image: url('http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Piece-of-cake-icon.png');
}

I prefer the -fx-graphic specification over the -fx-background-* specifications as the rules for styling background images are tricky and setting the background does not automatically size the button to the image, whereas setting the graphic does.

And some sample code:

import javafx.application.Application;
import javafx.scene.*;
import javafx.scene.control.ToggleButton;
import javafx.scene.layout.StackPaneBuilder;
import javafx.stage.Stage;

public class ToggleButtonImage extends Application {
  public static void main(String[] args) throws Exception { launch(args); }
  @Override public void start(final Stage stage) throws Exception {
    final ToggleButton toggle = new ToggleButton();
    toggle.getStylesheets().add(this.getClass().getResource(
      "imagetogglebutton.css"
    ).toExternalForm());
    toggle.setMinSize(148, 148); toggle.setMaxSize(148, 148);
    stage.setScene(new Scene(
      StackPaneBuilder.create()
        .children(toggle)
        .style("-fx-padding:10; -fx-background-color: cornsilk;")
        .build()
    ));
    stage.show();
  }
}

Some advantages of doing this are:

1. You get the default toggle button behavior and don't have to re-implement it yourself by adding your own focus styling, mouse and key handlers etc.
2. If your app gets ported to different platform such as a mobile device, it will work out of the box responding to touch events rather than mouse events, etc.
3. Your styling is separated from your application logic so it is easier to restyle your application.

An alternate is to not use css and still use a ToggleButton, but set the image graphic in code:

import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.scene.*;
import javafx.scene.control.ToggleButton;
import javafx.scene.image.*;
import javafx.scene.layout.StackPaneBuilder;
import javafx.stage.Stage;

public class ToggleButtonImageViaGraphic extends Application {
  public static void main(String[] args) throws Exception { launch(args); }
  @Override public void start(final Stage stage) throws Exception {
    final ToggleButton toggle      = new ToggleButton();
    final Image        unselected  = new Image(
      "http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Pizza-icon.png"
    );
    final Image        selected    = new Image(
      "http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Piece-of-cake-icon.png"
    );
    final ImageView    toggleImage = new ImageView();
    toggle.setGraphic(toggleImage);
    toggleImage.imageProperty().bind(Bindings
      .when(toggle.selectedProperty())
        .then(selected)
        .otherwise(unselected)
    );

    stage.setScene(new Scene(
      StackPaneBuilder.create()
        .children(toggle)
        .style("-fx-padding:10; -fx-background-color: cornsilk;")
        .build()
    ));
    stage.show();
  }
}

The code based approach has the advantage that you don't have to use css if you are unfamilar with it.

For best performance and ease of porting to unsigned applet and webstart sandboxes, bundle the images with your app and reference them by relative path urls rather than downloading them off the net.

This is the problem

double a[] = null;

Since a is null, NullPointerException will arise every time you use it until you initialize it. So this:

a[i] = var;

will fail.

A possible solution would be initialize it when declaring it:

double a[] = new double[PUT_A_LENGTH_HERE]; //seems like this constant should be 7

IMO more important than solving this exception, is the fact that you should learn to read the stacktrace and understand what it says, so you could detect the problems and solve it.

java.lang.NullPointerException

This exception means there's a variable with null value being used. How to solve? Just make sure the variable is not null before being used.

at twoten.TwoTenB.(TwoTenB.java:29)

This line has two parts:

• First, shows the class and method where the error was thrown. In this case, it was at <init> method in class TwoTenB declared in package twoten. When you encounter an error message with SomeClassName.<init>, means the error was thrown while creating a new instance of the class e.g. executing the constructor (in this case that seems to be the problem).
• Secondly, shows the file and line number location where the error is thrown, which is between parenthesis. This way is easier to spot where the error arose. So you have to look into file TwoTenB.java, line number 29. This seems to be a[i] = var;.

From this line, other lines will be similar to tell you where the error arose. So when reading this:

at javapractice.JavaPractice.main(JavaPractice.java:32)

It means that you were trying to instantiate a TwoTenB object reference inside the main method of your class JavaPractice declared in javapractice package.

We can use assert here.

def _input(inp_str:str):
    try:
        assert len(inp_str)<=15,print('More than 15 characters present')
        assert all('a'<=i<='z' for i in inp_str),print('Characters other than "a"-"z" are found')
        return inp_str
    except Exception as e:
        pass

_input('abcd')
#abcd
_input('abc d')
#Characters other than "a"-"z" are found
_input('abcdefghijklmnopqrst')
#More than 15 characters present

You are creating an array of null references. You should do something like:

for (int i = 0; i < houses.Count; i++)
{
    houses[i] = new GameObject();
}

You could do this

WITH V(A,B) AS (VALUES 
     (2555,111111259)    
    ,(2724,111111261)     
    ,(2021,111111263)    
    ,(2017,111111264)    

    )
SELECT COUNT(*) FROM NEW TABLE (
    UPDATE table
    SET id =     (SELECT B FROM V WHERE ID = A)
    WHERE EXISTS (SELECT B FROM V WHERE ID = A)
) 

Note, does not works on column organized tables. Use MERGE in that case

Wget currently only supports x-www-form-urlencoded data. --post-file is not for transmitting files as form attachments, it expects data with the form: key=value&otherkey=example.

--post-data and --post-file work the same way: the only difference is that --post-data allows you to specify the data in the command line, while --post-file allows you to specify the path of the file that contain the data to send.

Here's the documentation:

 --post-data=string
       --post-file=file
           Use POST as the method for all HTTP requests and send the specified data
           in the request body.  --post-data sends string as data, whereas
           --post-file sends the contents of file.  Other than that, they work in
           exactly the same way. In particular, they both expect content of the
           form "key1=value1&key2=value2", with percent-encoding for special
           characters; the only difference is that one expects its content as a
           command-line parameter and the other accepts its content from a file. In
           particular, --post-file is not for transmitting files as form
           attachments: those must appear as "key=value" data (with appropriate
           percent-coding) just like everything else. Wget does not currently
           support "multipart/form-data" for transmitting POST data; only
           "application/x-www-form-urlencoded". Only one of --post-data and
           --post-file should be specified.

Regarding your authentication token, it should either be provided in the header, in the path of the url, or in the data itself. This must be indicated somewhere in the documentation of the service you use. In a POST request, as in a GET request, you must specify the data using keys and values. This way the server will be able to receive multiple information with specific names. It's similar with variables.

Hence, you can't just send a magic token to the server, you also need to specify the name of the key. If the key is "token", then it should be token=YOUR_TOKEN.

wget --post-data 'user=foo&password=bar' http://example.com/auth.php

Also, you should consider using curl if you can because it is easier to send files using it. There are many examples on the Internet for that.

        while((entrada = br.readLine())!=null){

            }

            System.out.println(x>y ?(x-y)+"":(y-x)+"");
        }
    }
}

This solution is a bit more efficient than the one above because it takes up the 2.128 and this takes 1.308 seconds to solve the problem.

Here is it: http://www.htmlcssvqs.com/8ed/examples/chapter-17/webm-video-with-autoplay-loop.html You have to add the tags: autoplay="autoplay" loop="loop" or just "autoplay" and "loop".

1. Opened package.json
2. Changed "@angular-devkit/build-angular": "^0.800.0" to "@angular-devkit/build-angular": "^0.10.0" or changed Changing from "@angular-devkit/build-angular": "^0.802.1" to "@angular-devkit/build-angular": "^0.13.9"
3. Run npm install
4. Run ng serve

The original version can be diferent, but is necessary change it at 0.10.0 or 0.13.9 version that fix the problem

The following correct answer was provided in the comment section of the question by Felix Kling:

if (!$.trim(data)){   
    alert("What follows is blank: " + data);
}
else{   
    alert("What follows is not blank: " + data);
}

What works for me is that: File > Import > Existing Project into Workspace (under General tab), then choose the project root folder. The importing of Existing Android Code into Workspace somehow does not work on Eclipse for me.

You don't need to use a type assertion, instead just use the %v format specifier with Sprintf:

hostAndPort := fmt.Sprintf("%v:%v", arguments["<host>"], arguments["<port>"])

string userName;
string userId;
if (HttpContext.Current != null && HttpContext.Current.User != null 
        && HttpContext.Current.User.Identity.Name != null)
{
    userName = HttpContext.Current.User.Identity.Name;
    userId = HttpContext.Current.User.Identity.GetUserId();
}

Or based on Darrel Miller's comment, maybe use this to retrieve the HttpContext first.

// get httpContext
object httpContext;
actionContext.Request.Properties.TryGetValue("MS_HttpContext", out httpContext);

I don't think you're supposed to be able to do this, but I have successfully injected a service into a config block. (AngularJS v1.0.7)

    .factory('dogmaCacheBuster', [
        function() {
            return function(path) {
                return path + '?_=' + Date.now();
            };
        }
    ]);

angular.module('touch', [

        function($routeProvider, cacheBuster) {
            var bust = cacheBuster.$get[0]();

            $routeProvider
                .when('/', {
                    templateUrl: bust('touch/customer'),
                    controller: 'CustomerCtrl'

On a Debian-based system (on the remote machine) Install:

sudo apt-get install tmux

Usage:

tmux

run commands you want

To rename session:

Ctrl+B then $

set Name

To exit session:

Ctrl+B then D

(this leaves the tmux session). Then, you can log out of SSH.

When you need to come back/check on it again, start up SSH, and enter

tmux attach session_name

It will take you back to your tmux session.

How about using good(?) old goto?

:loop

This type of situation is implementation dependent and consequently it will require a vendor specific mechanism in order to trap. With Microsoft this will involve SEH, and *nix will involve a signal

In general though catching an Access Violation exception is a very bad idea. There is almost no way to recover from an AV exception and attempting to do so will just lead to harder to find bugs in your program.

HashSet<T> is what you're looking for. From MSDN (emphasis added):

The HashSet<T> class provides high-performance set operations. A set is a collection that contains no duplicate elements, and whose elements are in no particular order.

Note that the HashSet<T>.Add(T item) method returns a bool -- true if the item was added to the collection; false if the item was already present.

I wanted to riff off @Christian Landgren's answer above. I was confused why my CSV file only had 3 columns/headers. This was because the first element in my json only had 3 keys. So you need to be careful with the const header = Object.keys(json[0]) line. It's assuming that the first element in the array is representative. I had messy JSON that with some objects having more or less.

So I added an array.sort to this which will order the JSON by number of keys. So that way your CSV file will have the max number of columns.

This is also a function that you can use in your code. Just feed it JSON!

function convertJSONtocsv(json) {
    if (json.length === 0) {
        return;
    }

    json.sort(function(a,b){ 
       return Object.keys(b).length - Object.keys(a).length;
    });

    const replacer = (key, value) => value === null ? '' : value // specify how you want to handle null values here
    const header = Object.keys(json[0])
    let csv = json.map(row => header.map(fieldName => JSON.stringify(row[fieldName], replacer)).join(','))
    csv.unshift(header.join(','))
    csv = csv.join('\r\n')

    fs.writeFileSync('awesome.csv', csv)
}

var itemIndex = listObject.FindIndex(x => x == SomeSpecialCondition());
var item = listObject.ElementAt(itemIndex);
item.SomePropYouWantToChange = "yourNewValue";

Use setItem and getItem if you want to write simple strings to localStorage. Also you should be using text() if it's the text you're after as you say, else you will get the full HTML as a string.

Sample using .text()

// get the text
var text = $('#test').text();

// set the item in localStorage
localStorage.setItem('test', text);

// alert the value to check if we got it
alert(localStorage.getItem('test'));

JSFiddle: https://jsfiddle.net/f3zLa3zc/

Storing the HTML itself

// get html
var html = $('#test')[0].outerHTML;

// set localstorage
localStorage.setItem('htmltest', html);

// test if it works
alert(localStorage.getItem('htmltest'));

JSFiddle:
https://jsfiddle.net/psfL82q3/1/

Update on user comment

A user want to update the localStorage when the div's content changes. Since it's unclear how the div contents changes (ajax, other method?) contenteditable and blur() is used to change the contents of the div and overwrite the old localStorage entry.

// get the text
var text = $('#test').text();

// set the item in localStorage
localStorage.setItem('test', text);

// bind text to 'blur' event for div
$('#test').on('blur', function() {

    // check the new text
    var newText = $(this).text();

    // overwrite the old text
    localStorage.setItem('test', newText);

    // test if it works
    alert(localStorage.getItem('test'));

});

If we were using ajax we would instead trigger the function it via the function responsible for updating the contents.

Note : This answer is now out-of-date. This changes the theme in "preview" only as @imjohnking and @john-ktejik pointed out. As @Shahzeb mentioned, theme can modified in res>values>styles

Android Studio 0.8.2 provides a slightly easier way to change the theme. In the preview window, you can select the theme of "Holo.Light.DarkActionBar" by clicking on the theme combo box just above the phone.

Or do a ctrl + click on the @style/AppTheme in the Android manifest file. It will open styles.xml file where you can change the parent attribute of the style tag.

• Theme.Holo for a "dark" theme.
• Theme.Holo.Light for a "light" theme.

When using the Support Library, you must instead use the Theme.AppCompat themes:

• Theme.AppCompat for the "dark" theme.
• Theme.AppCompat.Light for the "light" theme.
• Theme.AppCompat.Light.DarkActionBar for the light theme with a dark action bar.

The json is kind of odd, it's like the students are properties of the "GetQuestion" object, it should be easy to be a List.....

About the libraries you could use are.

• JavaScriptSerializer
• NewtonSoft.Json
• SimpleJson ...

And there could be many more, but that are what I've used

About the json I don't now maybe something like this

public class GetQuestions
{
    public List<Student> Questions { get; set; }
}

public class Student
{
    public string Code { get; set; }
    public string Questions { get; set; }
}

void Main()
{
    var gq = new GetQuestions
    {
        Questions = new List<Student>
        {
            new Student {Code = "s1", Questions = "Q1,Q2"},
            new Student {Code = "s2", Questions = "Q1,Q2,Q3"},
            new Student {Code = "s3", Questions = "Q1,Q2,Q4"},
            new Student {Code = "s4", Questions = "Q1,Q2,Q5"},
        }
    };

    //Using Newtonsoft.json. Dump is an extension method of [Linqpad][4]
    JsonConvert.SerializeObject(gq).Dump();
}

Linqpad

and the result is this

{
     "Questions":[
        {"Code":"s1","Questions":"Q1,Q2"},
        {"Code":"s2","Questions":"Q1,Q2,Q3"},
        {"Code":"s3","Questions":"Q1,Q2,Q4"},
        {"Code":"s4","Questions":"Q1,Q2,Q5"}
      ]
 }

Yes I know the json is different, but the json that you want with dictionary.

void Main()
{
    var f = new Foo
    {
        GetQuestions = new Dictionary<string, string>
                {
                    {"s1", "Q1,Q2"},
                    {"s2", "Q1,Q2,Q3"},
                    {"s3", "Q1,Q2,Q4"},
                    {"s4", "Q1,Q2,Q4,Q6"},
                }
    };

    JsonConvert.SerializeObject(f).Dump();
}

class Foo
{
    public Dictionary<string, string> GetQuestions { get; set; }
}

And with Dictionary is as you want it.....

{
      "GetQuestions":
       {
              "s1":"Q1,Q2",
              "s2":"Q1,Q2,Q3",
              "s3":"Q1,Q2,Q4",
              "s4":"Q1,Q2,Q4,Q6"
       }
 }

Pandas concat vs append vs join vs merge

• Concat gives the flexibility to join based on the axis( all rows or all columns)

• Append is the specific case(axis=0, join='outer') of concat

• Join is based on the indexes (set by set_index) on how variable =['left','right','inner','couter']

• Merge is based on any particular column each of the two dataframes, this columns are variables on like 'left_on', 'right_on', 'on'

In Workbench 6.3 it is supereasy:

1. On the "HOME"-view select one of the MySQL Connections: (localhost)
2. In the "Localhost" view click on "Server"--> "Data export"
3. In the "Data Export" view select the table(s) and whether you want to export only their structure, or structure and data,...
4. Click "Start Export"

Example: to view the Windows User Name on Cell C5, you can use this script :

Range("C5").Value = ": " & Environ("USERNAME").

Output of perldoc -q round

Does Perl have a round() function? What about ceil() and floor()? Trig functions?

Remember that int() merely truncates toward 0. For rounding to a certain number of digits, sprintf() or printf() is usually the easiest route.

    printf("%.3f", 3.1415926535);       # prints 3.142

The POSIX module (part of the standard Perl distribution) implements ceil(), floor(), and a number of other mathematical and trigonometric functions.

    use POSIX;
    $ceil   = ceil(3.5);                        # 4
    $floor  = floor(3.5);                       # 3

In 5.000 to 5.003 perls, trigonometry was done in the Math::Complex module. With 5.004, the Math::Trig module (part of the standard Perl distribution) implements the trigonometric functions. Internally it uses the Math::Complex module and some functions can break out from the real axis into the complex plane, for example the inverse sine of 2.

Rounding in financial applications can have serious implications, and the rounding method used should be specified precisely. In these cases, it probably pays not to trust whichever system rounding is being used by Perl, but to instead implement the rounding function you need yourself.

To see why, notice how you'll still have an issue on half-way-point alternation:

    for ($i = 0; $i < 1.01; $i += 0.05) { printf "%.1f ",$i}

    0.0 0.1 0.1 0.2 0.2 0.2 0.3 0.3 0.4 0.4 0.5 0.5 0.6 0.7 0.7
    0.8 0.8 0.9 0.9 1.0 1.0

Don't blame Perl. It's the same as in C. IEEE says we have to do this. Perl numbers whose absolute values are integers under 2**31 (on 32 bit machines) will work pretty much like mathematical integers. Other numbers are not guaranteed.

You can't (usefully) compare strings using != or ==, you need to use strcmp:

while (strcmp(check,input) != 0)

The reason for this is because != and == will only compare the base addresses of those strings. Not the contents of the strings themselves.

You can use the IPython.display.clear_output to clear the output as mentioned in cel's answer. I would add that for me the best solution was to use this combination of parameters to print without any "shakiness" of the notebook:

from IPython.display import clear_output

for i in range(10):
    clear_output(wait=True)
    print(i, flush=True)

You can try the following code to get time as HH:MM format:

 SELECT CONVERT(VARCHAR(5),getdate(),108)

I just solved this by removing the __init__.py in my project root:

.
+-- __init__.py <--- removed
+-- models
¦   +-- __init__.py
¦   +-- address.py
¦   +-- appointment.py
¦   +-- client.py
+-- requirements.txt
+-- setup.cfg
+-- tests

¦   ¦   +-- appointment_test.py
¦   ¦   +-- client_test.py
¦   +-- other_test.py
+-- script.py

If you want to replace lot of values in single go, you can use 'library(car)'.

Example

library(car)

x <- rep(1:5,3)

xr <- recode(x, '3=1; 4=2')

x
## [1] 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5
xr
## [1] 1 2 1 2 5 1 2 1 2 5 1 2 1 2 5

My solution is based on XML configuration using spring-boot-starter-log4j. The example is a basic example using spring-boot-starter and the two Loggers writes into different log files.

There was a time when adding strings into an array and finalising the string by using join was the fastest/best method. These days browsers have highly optimised string routines and it is recommended that + and += methods are fastest/best

You can do like

HTML in PHP :

<?php
     echo "<table>";
     echo "<tr>";
     echo "<td>Name</td>";
     echo "<td>".$name."</td>";
     echo "</tr>";
     echo "</table>";
?>

Or You can write like.

PHP in HTML :

<?php /*Do some PHP calculation or something*/ ?>
     <table>
         <tr>
             <td>Name</td>
             <td><?php echo $name;?></td>
         </tr>
     </table>

<?php /*Do some PHP calculation or something*/ ?> Means:
You can open a PHP tag with <?php, now add your PHP code, then close the tag with ?> and then write your html code. When needed to add more PHP, just open another PHP tag with <?php.

int g[] = {9,8};

This declares an object of type int[2], and initializes its elements to {9,8}

int (*j) = g;

This declares an object of type int *, and initializes it with a pointer to the first element of g.

The fact that the second declaration initializes j with something other than g is pretty strange. C and C++ just have these weird rules about arrays, and this is one of them. Here the expression g is implicitly converted from an lvalue referring to the object g into an rvalue of type int* that points at the first element of g.

This conversion happens in several places. In fact it occurs when you do g[0]. The array index operator doesn't actually work on arrays, only on pointers. So the statement int x = j[0]; works because g[0] happens to do that same implicit conversion that was done when j was initialized.

A pointer to an array is declared like this

int (*k)[2];

and you're exactly right about how this would be used

int x = (*k)[0];

(note how "declaration follows use", i.e. the syntax for declaring a variable of a type mimics the syntax for using a variable of that type.)

However one doesn't typically use a pointer to an array. The whole purpose of the special rules around arrays is so that you can use a pointer to an array element as though it were an array. So idiomatic C generally doesn't care that arrays and pointers aren't the same thing, and the rules prevent you from doing much of anything useful directly with arrays. (for example you can't copy an array like: int g[2] = {1,2}; int h[2]; h = g;)

Examples:

void foo(int c[10]); // looks like we're taking an array by value.
// Wrong, the parameter type is 'adjusted' to be int*

int bar[3] = {1,2};
foo(bar); // compile error due to wrong types (int[3] vs. int[10])?
// No, compiles fine but you'll probably get undefined behavior at runtime

// if you want type checking, you can pass arrays by reference (or just use std::array):
void foo2(int (&c)[10]); // paramater type isn't 'adjusted'
foo2(bar); // compiler error, cannot convert int[3] to int (&)[10]

int baz()[10]; // returning an array by value?
// No, return types are prohibited from being an array.

int g[2] = {1,2};
int h[2] = g; // initializing the array? No, initializing an array requires {} syntax
h = g; // copying an array? No, assigning to arrays is prohibited

Because arrays are so inconsistent with the other types in C and C++ you should just avoid them. C++ has std::array that is much more consistent and you should use it when you need statically sized arrays. If you need dynamically sized arrays your first option is std::vector.

Unlike other languages you may be used to, everything in C++ has to be declared before it can be used. The compiler will read your source file from top to bottom, so when it gets to the call to swapCase, it doesn't know what it is so you get an error. You can declare your function ahead of main with a line like this:

void swapCase(char *name);

or you can simply move the entirety of that function ahead of main in the file. Don't worry about having the seemingly most important function (main) at the bottom of the file. It is very common in C or C++ to do that.

var requestedURL = "https://accounts.google.com/o/oauth2/token?code=" + code + "&client_id=" + client_id + "&client_secret=" + client_secret + "&redirect_uri=" + redirect_uri + "&grant_type=authorization_code";
HttpWebRequest authRequest = (HttpWebRequest)WebRequest.Create(requestedURL);
authRequest.ContentType = "application/x-www-form-urlencoded";
authRequest.Method = "POST";
//Set content length to 0
authRequest.ContentLength = 0;
WebResponse authResponseTwitter = authRequest.GetResponse();

The ContentLength property contains the value to send as the Content-length HTTP header with the request.

Any value other than -1 in the ContentLength property indicates that the request uploads data and that only methods that upload data are allowed to be set in the Method property.

After the ContentLength property is set to a value, that number of bytes must be written to the request stream that is returned by calling the GetRequestStream method or both the BeginGetRequestStream and the EndGetRequestStream methods.

Concatenating strings in awk can be accomplished by the print command AWK manual page, and you can do complicated combination. Here I was trying to change the 16 char to A and used string concatenation:

echo    CTCTCTGAAATCACTGAGCAGGAGAAAGATT | awk -v w=15 -v BA=A '{OFS=""; print substr($0, 1, w), BA, substr($0,w+2)}'
Output: CTCTCTGAAATCACTAAGCAGGAGAAAGATT

I used the substr function to extract a portion of the input (STDIN). I passed some external parameters (here I am using hard-coded values) that are usually shell variable. In the context of shell programming, you can write -v w=$width -v BA=$my_charval. The key is the OFS which stands for Output Field Separate in awk. Print function take a list of values and write them to the STDOUT and glue them with the OFS. This is analogous to the perl join function.

It looks that in awk, string can be concatenated by printing variable next to each other:

echo xxx | awk -v a="aaa" -v b="bbb" '{ print a b $1 "string literal"}'
# will produce: aaabbbxxxstring literal

Winston is a pretty good logging library. You can write logs out to a file using it.

Code would look something like:

var winston = require('winston');

var logger = new (winston.Logger)({
  transports: [
    new (winston.transports.Console)({ json: false, timestamp: true }),
    new winston.transports.File({ filename: __dirname + '/debug.log', json: false })
  ],
  exceptionHandlers: [
    new (winston.transports.Console)({ json: false, timestamp: true }),
    new winston.transports.File({ filename: __dirname + '/exceptions.log', json: false })
  ],
  exitOnError: false
});

module.exports = logger;

You can then use this like:

var logger = require('./log');

logger.info('log to file');

Set a breakpoint on malloc_error_break() by opening the Breakpoint Navigator (View->Navigators->Show Breakpoint Navigator or ?8), clicking the plus button in the lower left corner, and selecting "Add Symbolic Breakpoint". In the popup that comes up, enter malloc_error_break in the Symbol field, then click Done.

EDIT: openfrog added a screenshot and indicated that he's already tried these steps without success after I posted my answer. With that edit, I'm not sure what to say. I haven't seen that fail to work myself, and indeed I always keep a breakpoint on malloc_error_break set.

It should work with:

.modal:before{
   opacity:0.001 !important;
}

Just a thought, but Have you tried using application.undo

This will set the values back again. You can then simply read the original value. It should not be too difficult to store the new values first, so you change them back again if you like.

Read these tutorials Asp.net Update Panel and Introduction to the UpdatePanel Control

Simple and understandable

You will have to split your string into a list of values using split()

So,

lines = text_file.read().split(',')

EDIT: I didn't realise there would be so much traction to this. Here's a more idiomatic approach.

import csv
with open('filename.csv', 'r') as fd:
    reader = csv.reader(fd)
    for row in reader:
        # do something

since the Two Dimensional Scrollview link is dead I could not get it so I created my own component. It handles flinging and works properly for me. The only restriction is that wrap_content might not work properly for that component.

Consider using indexed-tree-map . It's an enhanced JDK's TreeSet that provides access to element by index and finding the index of an element without iteration or hidden underlying lists that back up the tree. The algorithm is based on updating weights of changing nodes every time there is a change.

// copy /tmp/abc.txt to /tmp/abc.txt (target path)

// username and password of 10.1.1.2 is "username" and "password"

sshpass -p "password" scp /tmp/abc.txt [email protected]:/tmp/abc.txt

// install sshpass (ubuntu)

sudo apt-get install sshpass

$("#grd").data("kendoGrid").dataSource.read();

WHAT "return false" IS REALLY DOING?

return false is actually doing three very separate things when you call it:

1. event.preventDefault();
2. event.stopPropagation();
3. Stops callback execution and returns immediately when called.

See jquery-events-stop-misusing-return-false for more information.

For example :

while clicking this link, return false will cancel the default behaviour of the browser.

<a href='#' onclick='someFunc(3.1415926); return false;'>Click here !</a>

By C89, variable can only be defined at the top of a block.

if (a == 1)
    int b = 10;   // it's just a statement, syntacitially error 

if (a == 1)
{                  // refer to the beginning of a local block 
    int b = 10;    // at the top of the local block, syntacitially correct
}                  // refer to the end of a local block

if (a == 1)
{
    func();
    int b = 10;    // not at the top of the local block, syntacitially error, I guess
}

DECLARE @dayNumber INT;
SET @dayNumber = DATEPART(DW, GETDATE());

--Sunday = 1, Saturday = 7.
IF(@dayNumber = 1 OR @dayNumber = 7) 
    PRINT 'Weekend';
ELSE
    PRINT 'NOT Weekend';

This may generate wrong results, because the number produced by the weekday datepart depends on the value set by SET DATEFIRST. This sets the first day of the week. So another way is:

DECLARE @dayName VARCHAR(9);
SET @dayName = DATEName(DW, GETDATE());

IF(@dayName = 'Saturday' OR @dayName = 'Sunday') 
    PRINT 'Weekend';
ELSE
    PRINT 'NOT Weekend';

I had a situation whereby I had to replace the HTML tags with two different replacement results.

$trades = "<li>Sprinkler and Fire      Protection Installer</li>
<li>Steamfitter </li>
<li>Terrazzo, Tile and Marble      Setter</li>";

$s1 =  str_replace('<li>', '"', $trades);

$s2 = str_replace('</li>', '",', $s1);

echo $s2;

result

"Sprinkler and Fire Protection Installer", "Steamfitter ", "Terrazzo, Tile and Marble Setter",

If you don't want to use jQuery mobile as like me. You can use Hammer.js

It's mostly like jQuery Mobile without unnecessary code.

$(document).ready(function() {
  Hammer(myCarousel).on("swipeleft", function(){
    $(this).carousel('next');
  });
  Hammer(myCarousel).on("swiperight", function(){
    $(this).carousel('prev');
  });
});

Here's a solution that uses a mix of jQuery and CSS3 animations.

http://jsfiddle.net/padfv0u9/2/

Essentially you start by changing the color to your "flash" color, and then use a CSS3 animation to let the color fade out. You need to change the transition duration in order for the initial "flash" to be faster than the fade.

$(element).removeClass("transition-duration-medium");
$(element).addClass("transition-duration-instant");
$(element).addClass("ko-flash");
setTimeout(function () {
    $(element).removeClass("transition-duration-instant");
    $(element).addClass("transition-duration-medium");
    $(element).removeClass("ko-flash");
}, 500);

Where the CSS classes are as follows.

.ko-flash {
    background-color: yellow;
}
.transition-duration-instant {
    -webkit-transition-duration: 0s;
    -moz-transition-duration: 0s;
    -o-transition-duration: 0s;
    transition-duration: 0s;
}
.transition-duration-medium {
    -webkit-transition-duration: 1s;
    -moz-transition-duration: 1s;
    -o-transition-duration: 1s;
    transition-duration: 1s;
}

The good practice is to use like this:

$.ajax({
    type: "POST",
    url: "/ajax/request.html",
    data: {action: 'test'},
    dataType:'JSON', 
    success: function(response){
        console.log(response.blablabla);
        // put on console what server sent back...
    }
});

and the php part is:

<?php
    if(isset($_POST['action']) && !empty($_POST['action'])) {
        echo json_encode(array("blablabla"=>$variable));
    }
?>

The compiler must provide a consistent type system, and provide a set of standard conversions. Neither the integer value 0 nor the NULL pointer need to be represented by all-zero bits, but the compiler must take care of converting the "0" token in the input file to the correct representation for integer zero, and the cast to pointer type must convert from integer to pointer representation.

The implication of this is that

void *p;
memset(&p, 0, sizeof p);
if(p) { ... }

is not guaranteed to behave the same on all target systems, as you are making an assumption about the bit pattern here.

As an example, I have an embedded platform that has no memory protection, and keeps the interrupt vectors at address 0, so by convention, integers and pointers are XORed with 0x2000000 when converted, which leaves (void *)0 pointing at an address that generates a bus error when dereferenced, however testing the pointer with an if statement will return it to integer representation first, which is then all-zeros.

A simple way that runs is

 var myselect = $("select.SimpleAddAClass");
 myselect[0].selectedIndex = 0;
 myselect.selectmenu("refresh");

I don't know a good free tool but winmerge is ok(ish). I've been using the beyond compare tools since 1999 and can't rate it enough - it costs about 50 USD and this investment has paid for it self in time savings more than I can possible imagine.

Sometimes tools should be paid for if they are very very good.
