I am trying to display some JavaScript variable on my HTML page.
I was first using document.write() but it use to overwrite the current page when the function was called.
After searching around, the general consensus was that document.write() isn't liked very much. What are the other options?
I found a page suggesting using .innerHTML but that was written in 2005.
A jsFiddle illustrating my problem http://jsfiddle.net/xHk5g/
This question is related to
javascript
jquery
html
You could use jquery to get hold of the html element that you want to load the value with.
Say for instance if your page looks something like this,
<div id="FirstDiv">
<div id="SecondDiv">
...
</div>
</div>
And if your javascript (I hope) looks something as simple as this,
function somefunction(){
var somevalue = "Data to be inserted";
$("#SecondDiv").text(somevalue);
}
I hope this is what you were looking for.
there are different ways of doing this. one way would be to write a script retrieving a command. like so:
var name="kieran";
document.write=(name);
or we could use the default JavaScript way to print it.
var name="kieran";
document.getElementById("output").innerHTML=name;
and the html code would be:
<p id="output"></p>
i hope this helped :)
You can use javascript to access elements on the page and modify their contents. So for example you might have a page with some HTML markup like so:
<div id="MyEdit">
This text will change
</div>
You can use javascript to change the content like so...
document.getElementById("MyEdit").innerHTML = "My new text!";?
You can also look at using the JQuery javascript library for DOM manipulation, it has some great features to make things like this very easy.
For example, with JQuery, you could do this to acheive the same result...
$("#MyEdit").html("My new text!");
Here is a working example of the JQuery version
Based on this example you provided in your post. The following JQuery would work for you:
var x = "hello wolrd";
$("p").html(x);
Using a P tag like this however is not recommended. You would ideally want to use an element with a unique ID so you can ensure you are selecting the correct one with JQuery.
innerHTML is fine and still valid. Use it all the time on projects big and small. I just flipped to an open tab in my IDE and there was one right there.
document.getElementById("data-progress").innerHTML = "<img src='../images/loading.gif'/>";
Not much has changed in js + dom manipulation since 2005, other than the addition of more libraries. You can easily set other properties such as
uploadElement.style.width = "100%";
If you want to avoid innerHTML you can use the DOM methods to construct elements and append them to the page.
?var element = document.createElement('div');
var text = document.createTextNode('This is some text');
element.appendChild(text);
document.body.appendChild(element);??????
Similar to above, but I used (this was in CSHTML):
JavaScript:
var value = "Hello World!"<br>
$('.output').html(value);
CSHTML:
<div class="output"></div>
hi here is a simple example: <div id="test">content</div> and
var test = 5;
document.getElementById('test').innerHTML = test;
and you can test it here : http://jsfiddle.net/SLbKX/
Add an element to your page (such as a div) and write to that div.
HTML:
<html>
<header>
<title>Page Title</title>
</header>
<body>
<div id="myDiv"></div>
</body>
</html>
jQuery:
$('#myDiv').text('hello world!');
javascript:
document.getElementById('myDiv').innerHTML = 'hello world!';
