How come this code throws an
Uncaught ReferenceError: $ is not defined
when it was OK before?
$(document).ready(function() {
$('#tabs > ul').tabs({ fx: { opacity: 'toggle' } });
$('#featuredvid > ul').tabs();
});
Results in tabs don't close anymore.
jQuery is referenced in the header:
<script language="JavaScript" type="text/javascript" src="<?php echo get_option('siteurl') ?>/js/sprinkle.js"></script>
<script language="JavaScript" type="text/javascript" src="<?php echo get_option('siteurl') ?>/js/jquery-1.2.6.min.js"></script>
<script language="JavaScript" type="text/javascript" src="<?php echo get_option('siteurl') ?>/js/jquery-ui-personalized-1.5.2.packed.js"></script>
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>
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>
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.
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.
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(){ });
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() {
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.
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>
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.
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>
Include the jQuery CDN (or jQuery ref) in the index file first. before including your JS file to ensure we are accessing the jQuery.
following lines worked for me
Can get a clear idea about this by referring to the following link
reference site:
https://www.tutorialrepublic.com/faq/how-to-fix-dollar-is-not-defined-error-in-jquery.php
Answer: Execute Code after jQuery Library has Loaded
The most common reason behind the error "Uncaught ReferenceError: $ is not defined" is executing the jQuery code before the jQuery library file has loaded. Therefore make sure that you're executing the jQuery code only after jQuery library file has finished loading.
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>
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()
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 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.
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.
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>
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.
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.
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.
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 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.
if you are laraveling that error comes on in blade files when you forgot to surround the code with :
#section('section name')
.......
#endsection
Is it possible to run ckeditor on an IFrame so that can encapsulate a full html page? I have tried various methods but nothing seems to work.
What I am looking for is to have a ckeditor wrapper page say Editor.htm which contains an editable IFrame linked to my real html page say test.htm. Something line:
Editor.htm
<!DOCTYPE html>
<html>
<head>
<script src="http://cdn.ckeditor.com/4.5.10/standard-all/ckeditor.js"></script>
</head>
<body>
<iframe contenteditable="true" src="test.htm" id="editor1" name="editor1"></iframe>
</body>
</html>
You can set ckeditor to use "fullPage" mode, allowing you to edit everything from the opening tag to the closing tag. See the official sample here.
You will still need to get the content into the editor (e.g. the html page you want to edit) and save the result on the server, but this is something specific to your site, language, platform etc.
I'm trying to embed a Vimeo video using fancyBox 2. I'm able to make the lightbox pop up, but all I get is a spinning loading icon that lasts forever.
I did a bunch of searching on similar Vimeo questions here on StackExchange, but implementing things others suggested has not solved the issue.
I've now even created a fresh test site (plain HTML doc with linked files in local directory), and then used the code listed in the fancyBox documentation section on using Media Helpers (Extended Functionality) line-for-line, but that's not working either. Same loading spinner, stuck forever.
Does anyone have any ideas why this is not working? Testing in both Safari 7 and Chrome. In Safari I get the stuck loading spinner. In Chrome I get an error page within the lightbox that says "The file or directory could not be found."
Here's my code:
<!DOCTYPE HTML>
<head>
<!-- Add jQuery library -->
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
<!-- Add fancyBox -->
<link rel="stylesheet" href="js/fancybox/jquery.fancybox.css?v=2.1.5" type="text/css" media="screen" />
<script type="text/javascript" src="js/fancybox/jquery.fancybox.pack.js?v=2.1.5"></script>
<!-- Add fancyBox media helpers -->
<script type="text/javascript" src="js/fancybox/helpers/jquery.fancybox-media.js?v=1.0.6"></script>
<script type="text/javascript">
$(document).ready(function() {
$('.fancybox-media').fancybox({
openEffect : 'none',
closeEffect : 'none',
helpers : {
media : {}
}
});
});
</script>
</head>
<body>
<a class="fancybox-media" href="https://vimeo.com/78112273">Video</a>
</body>
All I get with that is a stuck spinner and an error page.
Any help and suggestions are greatly appreciated! Thank you!
Ensure your page has a valid DOCTYPE and most importantly, note that the case seems to impact on whether the video actually gets loaded when the popup is displayed. (You need lowercase 'html' in the doctype declaration)
ie. Using:
<!DOCTYPE html>
<html>
<head>
fixed it for me... This is probably why your example works in jsfiddle.
I have a MVC3 view, local debug perfectly fine, after I deployed to server I found unobtrusive validation is not fired at all.
I saved the output to a static HTML file and get rid all unnecessary codes and with following section remaining
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<script type="text/javascript" src="/Scripts/jquery.validate.js"></script>
<script type="text/javascript" src="/Scripts/jquery.validate.unobtrusive.js"></script>
<script type="text/javascript" src="/Scripts/jquery.unobtrusive-ajax.js"></script>
</head>
<body>
<form action="/Test/Dummy" data-ajax="true" data-ajax-complete="MyDummy.OnComplete" data-ajax-method="Post" id="form0" method="post">
<select data-val="true" data-val-number="The field SourceId must be a number." data-val-required="SourceId required." id="SourceId" name="SourceId"></select>
<span class="field-validation-valid" data-valmsg-for="SourceId" data-valmsg-replace="true"></span><br />
<select data-val="true" data-val-number="The field DestinationId must be a number." data-val-required="DestinationId required." id="DestinationId" name="DestinationId"></select>
<span class="field-validation-valid" data-valmsg-for="DestinationId" data-valmsg-replace="true"></span><br />
<input type="submit" value=" Submit " class="ButtonStyle" />
</form>
<script type="text/javascript">
var MyDummy = {
OnComplete: function (content) {
alert(content.responseText);
}
}
</script>
</body>
</html>
I believe I have included proper JavaScript files, all the rendered Html looks fine to me. When I click on the submit button I expect validation message, but instead the oncomplete event fires.
I am very lost here, anybody has clue what is wrong?
Edit 1, I copied the same static Html file to my local project's folder and access it via http://localhost:48194/test.htm (my local ASP.NET Development Server) and everything works fine. But if I load the same file from 2008 server's local IE8 at http://localhost:87/test.htm (IIS 7) then I got the issue. Somehow it leads me to think is there something wrong setting IIS7 which blocks or partially blocks the access to JavaScript files properly?
Edit 2,
If I change the JS reference to use CDN like
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.6.4.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.validate.unobtrusive.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.unobtrusive-ajax.js"></script>
Then it works. I really don't know now what IIS7 could do to damage the local JS file transportation.
I does sound like IIS blocks the javascript.
In IIS you can set filters for which files are allowed or denied. Maybe for some reason someone (accidentally) blocked .js? - Another issue could be file access. IIS normally runs under a different user, so maybe it does not have access?
But I'm kind of just guessing. So the easiest way to test this is to just visit the .js file directly. So just open your http://localhost:87/Scripts/jquery-1.6.4.js and check what IIS returns. Maybe it returns a 403 error, maybe something else, at least it'll probably help to figure out what's wrong.
