I am getting this error message when trying to create a JQuery image slider.

My folder path to the JS folder for my website (locally) looks like this: C:\Users\Andrew\Desktop\GCFS\JS
I am new to the coding world, but what I am trying to achieve is fairly simple. As far as I know I do not need to have a ready function and the javascript should run automatically. Thank you for your assistance!
From comment
When I tried this it also failed
<title>Green Cold-Formed Steel | Home</title>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script src="JS/jquery.cycle.all.js"></script>
<script type="text/javascript">
$(function() {
$('#slider').cycle({ fx: 'scrollHorz', speed: 'fast', next: '#next', prev: '#prev' });
});

This question is related to
javascript
jquery
image
referenceerror
The answer is
You should put the references to the jquery scripts first.
<script language="JavaScript" type="text/javascript" src="/js/jquery-1.2.6.min.js"></script>
<script language="JavaScript" type="text/javascript" src="/js/jquery-ui-personalized-1.5.2.packed.js"></script>
<script language="JavaScript" type="text/javascript" src="/js/sprinkle.js"></script>
You are calling the ready function before the jQuery JavaScript is included. Reference jQuery first.
This is what solved it for me. Originally I went to Google and copied and pasted their suggested snippet for jQuery on their CDN page:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
The snippet does not include the HTTP: or HTTPS: in the src attribute but my browser, FireFox, needed it so I changed it to:
edit: this worked for me with Google Chrome as well
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
Then it worked.
If your custom script is loaded before the jQuery plugin is loaded to the browser then this type of problem may occur. So, always keep your own JavaScript or jQuery code after calling the jQuery plugin so the solution for this is :
First add the link to the jQuery file hosted at GoogleApis or a local jQuery file that you will download from http://jquery.com/download/ and host on your server:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
or any plugin for jQuery. Then put your custom script file link or code:
<script src="js/custom.js" type="text/javascript"></script>
In my case I was putting my .js file before the jQuery script link, putting the .js file after jQuery script link solved my issue.
<script src="http://code.jquery.com/jquery-1.10.2.js"></script>
<script src="http://code.jquery.com/ui/1.11.2/jquery-ui.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
<script src="exponential.js"></script>
Okay, my problem was different - it was Document Security model in Chrome.
Looking at the answers here, it was obvious that I was somehow not loading my jquery files before calling the $(document).ready() etc. functions. However, they were all in the correct positions.
In my case, this was because I was accessing the content over a secure HTTPS connection, whereas the page was trying to download the CDN hosted data from google, etc. The solution was to store them locally and then include then directly rather than from the CDN each time.
Edit: The other way of doing this is to link to all the CDN-hosted stuff as https:// rather than http:// - then the model doesn't complain.
Add the library before you start the script.You can add any of these following CDN to start it.
Google:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
Microsoft
<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js"></script>
Jquery
If you want any other Jquery cdn version check this link.
After this:
<script type="text/javascript">
$(function(){
//your stuff
});
or
$(document).ready(function(){
//your stuff
});
</script>
Wordpress:
<script type="text/javascript">
var $ = jQuery;
jQuery(document).ready(function($){
//your stuff
});
</script>
I had the exact same problem and none of these solutions above helped.
however, I just linked the .css files after the .js files and the problem miraculously disappeared. Hope this helps.
If it's in wordpress, might be needed to change
$(document).ready(function() {
to
jQuery(document).ready(function($){
or add
var $ = jQuery;
before
$(document).ready(function() {
In my case I had this referenceError as the order of script calls was wrong. Solved that by changing the order:
<script src="js/index.js"></script>
<script src="js/jquery-1.10.2.js"></script>
to
<script src="js/jquery-1.10.2.js"></script>
<script src="js/index.js"></script>
I wanted to try to make my script asynchronous. Then I forgot about it and when I went live the [custom].js file only loaded 50% of the time before the jQuery.js.
So I changed
<script async src="js/script.js"></script>
to
<script src="js/script.js"></script>
You are calling the ready() function before the jQuery JavaScript is included. Reference jQuery first.
If you're in ASP.NET MVC, you can specify when your JS code should be rendered, by doing this:
1, In your page.cshtml wrap your <script> tag into a section, and give it a name, the common name to use is 'scripts':
@section scripts {
<script>
// JS code...
</script>
}
2, In your _Layout.cshtml page add @RenderSection("Scripts", required: false), make sure to put it after you reference the Jquery source, this will make your JS code render later than the Jquery.
I had the same problem , and I solved by putting jQuery at the top of all javascript codes I have in my code.
Something like this:
<script src="https://code.jquery.com/jquery-3.3.1.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
<script src="js/app.js" type="text/javascript"></script>
<script src="js/form.js" type="text/javascript"></script>
<script src="js/create.js" type="text/javascript"></script>
<script src="js/tween.js" type="text/javascript"></script>
Hope can help some one in future.
2 issues.
Looks like your jQuery was not loaded properly.
You generally see this error
Uncaught ReferenceError:$ is not defined
when jQuery was not properly included on your page.
Try using jQuery from CDN and it should solve your problem
Replace
<script src="JS/jquery-1.10.1.min.js"></script>
with the one from cdn
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
NOTE: if you test from file system, you need to add the http: to the above URL or it will fail
Next your script file is before the HTML . So need to contain the code in DOM Ready handler.
$(function() {
$('#slider').cycle({
fx: 'scrollHorz',
speed: 'fast',
next: '#next',
prev: '#prev'
});
});
As far as I know 'Slider' was referenced when I created the div Id.
No it is not. If your script was included just before the body , then you may not enclose it in the Ready handler. But in your case it is present in the head. So when the script starts running that particular element is still not present in the DOM
In my case it was a typo, I forgot a backslash and was referencing the source incorrectly.
Before src="/scripts/jquery.js"
After src="scripts/jquery.js"
If you are doing this in .Net and have the script file referenced properly and you jQuery looks fine, make sure that your users have access to the script file. The project I was working on (a coworker) had their web.config denying access to anonymous users. The page I was working on was accessible to anonymous users therefore they didn't have access to the script file. Dropped the following into the web.config and all was right in the world:
<location path="Scripts">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>
This happened to me before.
The reason was that I'm connecting android to a webview with a JS. And I sent a parameter without quotes.
js.sayHello(hello);
and when I changed it to
js.sayHello('hello');
it worked.
The source file jquery-1.2.6.min.js is not called the jQuery command $() is executed earlier than <..src='jquery-1.2.6.min.js'>.
Please run <.. src="/js/jquery-1.2.6.min.js.."> at first and make sure the src path is right, then execute jquery command
$(document).ready(function()
put latest jquery cdn on top of your main html page
Like If your main html page is index.html
place jquery cdn on top of this page like this
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
$("h2").hide();
});
});
</script>
</head>
<body>
<h2>This will hide me</h2>
<button>Click me</button>
</body>
</html>Your JavaScript file is missing so this error occurred. Just add the JavaScript file inside the <head> tag. See the example:
<script src="js/sample.js" type="text/javascript"></script>
<link href="css/sample.css" rel="stylesheet" type="text/css" />
or add the following code in tag :
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
The error will occur in the following two scenarios as well.
- @section scripts element is missing from the HTML file
- Error in accessing DOM elements. For example accessing of DOM element is mentioned as $("js-toggle") instead of $(".js-toggle"). Actually the period is missing
So 3 things to be followed - check required scripts are added, check if it is added in the required order and third syntax errors in your Java Script.
There might be two issues:
1) The JQuery might not have got loaded properly.
You could test it using Chrome. Key in $ or jQuery to check if it is loaded properly.
2) This is based on my experience in some JQuery.js which would have got bundled with other JS libraries, where $ will not be supported and you are forced to use jQuery instead of $ Check out for the below line in the js file that you have loaded in your project.
window.jQuery = window.$ = jQuery;
I see that by using http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js didn't work for me but I used http://code.jquery.com/jquery-1.7.2.min.js
Below is the only part in your code that I edited and it started working fine for me.
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
In my case i forgot to include this :
<script src ="jquery-2.1.1.js"></script>
Earlier I was including just jquery-mobile which was causing this error.
Doh! I had mixed quotes in my tags that caused the jquery reference to break. Doing an inspect in Chrome allowed me to see that the file wasn't properly linked.
I had similar issue. My test server was working fine with "http". However it failed in production which had SSL.
Thus in production, I added "HTPPS" instead of "HTTP" and in test, i kept as it is "HTTP".
Test:
wp_register_script( 'jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js', array(), null, false );
wp_register_script( 'custom-script', plugins_url( '/js/custom.js', __FILE__ ), array( 'jquery' ) );
Production:
wp_register_script( 'jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js', array(), null, false );
wp_register_script( 'custom-script', plugins_url( '/js/custom.js', __FILE__ ), array( 'jquery' ) );
Hope this will help someone who is working on wordpress.
You have not referenced a jQuery library.
You'll need to include a line similar to this in your HTML:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
I modified the script tag to point to the right content and changed the script order to be the right one in the editor. But totally forgot to save the change.
if you are laraveling that error comes on in blade files when you forgot to surround the code with :
@section('section name')
.......
@endsection
I had a similar issue and it was because I was missing a closing > on a style sheet link.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<script type="text/javascript" src="local_xxx.js"></script>
I have similar issue, and you know what, it's because of network is disconnected when I test in android device webview and I don't realize it, and the local js no problem to load because it doesn't need network. It seems ridiculous but it waste my ~1 hour to figure out it.
As an addition. If you are using $(Jquery) in your .js file. Logically all libs or frameworks should be before that .js file.
<script type="text/javascript" src="jquery-2.1.3.min.js"></script>
<script type="text/javascript" src="app.js"></script>
Strange enough, my problem was coming from PHP.
A REST API call was failing, and it was breaking the loading of the libraries afterwards. Since failure was from the REST call, it was not giving me a php compile error.
Keep this as an option also, if loading jquery seems ok.
I had this issue, when I was browsing internet through my mobile hotspot. it was also compressing images and added the following script at the bottom of body tag
<script language="javascript"><!--
bmi_SafeAddOnload(bmi_load,"bmi_orig_img");//-->
</script>
When I connected to proper wifi connection, all seems to work find for me. Hope this help someone.
This can also happen, if there is network issue. Which means, that even though the " jquery scripts " are in place, and are included prior to usage, since the jquery-scripts are not accessible, at the time of loading the page, hence the definitions to the "$" are treated as "undefined references".
FOR TEST/DEBUG PURPOSES :: You can try to access the "jquery-script" url on browser. If it is accessible, your page, should load properly, else it will show the said error (or other script relevant errors). Example - http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js should be accessible, on the browser (or browser context stances).
I had similar problem, in which I was able to load the html-page (using scripts) in my windows-host-browser, but was not able to load in vm-ubuntu. Solving the network issue, got the issue resolved.
Add jQuery library before your script which uses $ or jQuery so that $ can be identified in scripts. remove tag script on head and put end bady
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
then first write script in file js add
/*global $ */
$(document).ready(function(){ });
I had this problem but the cause was very different to scenarios reported above. My site was working everywhere except on my older Android (2.2). Turned out this device was rejecting the https certificate at the code.jquery.com CDN, so it was not loading JQuery. The fix was to load JQuery resources from the https Google CDN instead (using URLs named by others above).
This probably happens, when you forget to include your jQuery CDN or local path
Here is the worst case:
Everything seemed perfect. After spending a couple of hours I realized that the jquery file which is added in the correct position was actually a file with empty content!
You need to call jquery first and then call javascript,as java script depends on jquery, so it should be loaded before javascript and this solved my problem.
In my case, the problem has been solved after installing Windows Server Role Service 'Static Content'. ( OS : Windows Server 2008 R2 )
How to install the 'Static Content' Server Role Service :
- ( Assuming that the 'Web Server' Role is already installed ) > Run Server Manager > Click 'Roles' in left pane > click 'Add Role Services' in the 'Web Server' area in right pane > select 'Static Content' under 'Web Server / Common HTTP Features' > Click 'Next' > ...
var $ = jQuery;
jQuery(document).ready(function($){
Root problem is a ReferenceError. MDN indicates that a try/catch block is the proper tool for the job. In my case, I was getting uncaught reference error for a payment sdk/library. The below works for me.
try {
var stripe = Stripe('pk_test_---------');
} catch (e) {
stripe = null;
}
if(stripe){
//we are good to go now
}
Obviously the fix is to load whatever SDK/library, e.g. jQuery, prior to calling its methods but the try/catch does keep your shared JavaScript from barfing up errors in case you run that shared script on a page that doesn't load whatever library you use on a subset of pages.
I had this problem when tried to run different web-socket samples.
When pointing browser to 'http://localhost:8080/' I got this error, but pointing exactly to 'http://localhost:8080/index.html' gave no error since in 'index.html' all was fully ok - jquery was included before using $..
Somehow autoforwarding to index.html not fully worked
$(document).ready(function() {
$.getJSON("<?php echo site_url('cadmin/survey/chart_survey_assisten'); ?>", function (json) {
var acctregs = new Morris.Donut({
// ID of the element in which to draw the chart.
element: 'hadir-chart-bar-assisten',
// Chart data records -- each entry in this array corresponds to a point on
// the chart.
data: json,
xkey: 'label',
ykeys: ['value'],
labels: ['Nilai'],
barRatio: 0.4,
xLabelAngle: 35,
hideHover: 'auto',
resize: true
});
});
});
