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
I am trying to implement color picker provided here http://automattic.github.io/Iris/
Here is my libraries that i am including.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js"></script>
<script src="js/iris.min.js"></script>
and this is how i am implementing this code
$(document).ready(function() {
jQuery('#color-picker').iris();
});
this is how i have my input field
<input type="text" id='color-picker' value="#bada55" />
but i don't why i get this error
TypeError: jQuery(...).iris is not a function
jQuery('#color-picker').iris();
Seem like the path to your iris script is wrong which caused the browser cannot load the file. So you can check again to see if the path js/iris.min.js is correct.
You can check to see whether your file is loaded or not by going to network tab of either Firebug or Chrome developer tools. If it cannot load the URL which you've provided than you'll receive a 404 error not found in this tab.
Or you can also try to replace:
<script src="js/iris.min.js"></script>
with direct link from Github:
<script src="https://github.com/Automattic/Iris/blob/master/dist/iris.min.js"></script>
The last note is that you just need to include jQuery once, you can choose either version 1.10.2 or 1.8.3 which you know that version will compatible with your jQuery code.
I think this should be something wrong with the iris script here, try to use this version directly from their home page:
<script src="http://automattic.github.io/Iris/javascripts/iris.min.js"></script>
Fiddle Demo
Is your code placed in a way that would let it run before jQuery, jQueryUI and Iris is loaded? Make sure you place your own script file after the rest.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js"></script>
<script src="js/iris.min.js"></script>
<script>
$(document).ready(function() {
jQuery('#color-picker').iris();
});
</script>
You need to have link to jQuery and jQuery UI instead of adding jQuery twice.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js"></script>
<script src="js/iris.min.js"></script>
Then call iris on page load and it will work. Here is a link to working fiddle http://jsfiddle.net/WLru3/
PS: I have directly copy pasted code of iris in js code block, please use library link in your code instead.
Remove a line that includes jQuery 1.8.3 library
Make sure the path to iris.min.js is correct
I'm having some issues with prettyPhoto on one of my clients website. Here is the link for reference: http://www.browardmicrofilm.com/pages/kodak-vizit-essential.html
I've used prettyPhoto on multiple other websites without issue. However for some reason, this website just doesn't want to perform the script properly. Instead of opening an image in the lightbox clone, it simply opens it in a new page. Perhaps it has something to do with the hosting but either way, wanted to see what professionals like you think!
I'm using Firefox 26 (Mac version) and I used Firebug to determine the error:
TypeError: $ is not a function
$(document).ready(function(){
I've tried numerous solutions, including one that made me change "$" to "window.jQuery and then for some reason the next line in the code creates the same error.
Here's the my code for those of you that wish to skip the entire page source code:
In my header:
<link href="../prettyPhoto.css" rel="stylesheet" type="text/css"/>
<script type="text/javascript" src="../Scripts/jquery.prettyPhoto.js"></script>
<script type="text/javascript" src="../Scripts/jquery-1.6.1.min.js"></script>
The final script just before the closing body tag:
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
$("a[rel^='prettyPhoto']").prettyPhoto({
theme: 'light_rounded',
});
});
</script>
I know my links are good, which is why I'm not including them.
Vanilla jquery needs to be declared before any library built on top of it
<!--first, jquery-->
<script type="text/javascript" src="../Scripts/jquery-1.6.1.min.js"></script>
<!--then the rest-->
<script type="text/javascript" src="../Scripts/jquery.prettyPhoto.js"></script>
Error below is saying that jQuery is not loaded.
TypeError: $ is not a function
$(document).ready(function(){
Check your resources, my guess is that your paths are case sensitive and libraries are not being properly loaded.
<script type="text/javascript" src="../Scripts/jquery.prettyPhoto.js"></script>
<script type="text/javascript" src="../Scripts/jquery-1.6.1.min.js"></script>
Check your resources.
Make sure that jQuery is loaded before the plugin is loaded.
<script type="text/javascript" src="../Scripts/jquery-1.6.1.min.js"></script>
<script type="text/javascript" src="../Scripts/jquery.prettyPhoto.js"></script>
Ultimately I abandoned the prettyPhoto javascript and went with an alternative. Lightbox 2.0:
http://lokeshdhakar.com/projects/lightbox2/
It works just as I'd like and no problems.
I am using uniformjs to style some html element but when i try to update an element such as a check box using
$.uniform.update('input[type=checkbox]');
I get the error
$.uniform is undefined
any one else have an idea how to solve this?
I have both jQuery and the uniform.js added to the page.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript" charset="utf-8"></script>
<script src="js/jquery.uniform.min.js" type="text/javascript" charset="utf-8"></script>
What's weird is this worked when it was a regular HTML page and stopped working when i made it into a ASP.NET page and added custom form validators. Perhaps there is some clash?
Reason for this error is browser cant identify $.uniform which can be because of following two reasons:
You have not included uniform.js file to your page, check if a similar looking lines is present in your markup.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js"></script>
<script src="jquery.uniform.js"></script>
You are referencing it before its been loaded (have you included it at the end of the page, after the markup?)
You have to load all your dependencies and the current library itself to make it work.
For your css:
<link rel="stylesheet" href="uniform.default.css" media="screen" />
For your javascript:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js"></script>
<script src="jquery.uniform.js"></script>
Please, check this JSFiddle that I've build for you, showing uniformjs working.
I'm working on a modeling website for my girlfriend and she wants a large slideshow as background on the website. I used the JonDesign Gallery for that, which works nicely for this purpose and is relatively light-weight.
Now, for the contact form I'd like to use something Lightbox/Slimbox style. Slimbox works with Mootools, which is also used by JD Gallery. Unfortunately, Slimbox seems to conflict with JD Gallery and I can't figure out why. I checked the CSS for conflicts, but there are no elements ID'd or class'd twice. I looked at the code and couldn't immediately spot a conflict. I'm sure I missed something. I can't figure it out because I don't have much experience with JavaScript let alone Mootools or Slimbox.
Here's my (relevant) code.
Head
<link rel="stylesheet" href="css/layout.css" type="text/css" media="screen" charset="utf-8" />
<link rel="stylesheet" href="css/jd.gallery.css" type="text/css" media="screen" charset="utf-8" />
<link rel="stylesheet" href="css/slimbox.css" type="text/css" media="screen" />
<script type="text/javascript" src="scripts/mootools.js"></script>
<script src="scripts/mootools-1.2.1-core-yc.js" type="text/javascript"></script>
<script src="scripts/mootools-1.2-more.js" type="text/javascript"></script>
<script src="scripts/jd.gallery.js" type="text/javascript"></script>
<script src="scripts/jd.gallery.transitions.js" type="text/javascript"></script>
<script type="text/javascript" src="scripts/slimbox.js"></script>
Body
<script type="text/javascript">
function startGallery() {
var myGallery = new gallery($('myGallery'), {
timed: true,
showArrows: false,
showCarousel: false,
delay: 6000,
embedLinks: false,
showInfopane: false,
});
}
window.addEvent('domready', startGallery);
</script>
<div id="myGalleryBox">
Contact her
</p>
</div>
<div class="content" style="z-index:1;">
<div id="myGallery">
<div class="imageElement">
<h3>Item 2 Title</h3>
<p>Item 2 Description</p>
<img src="images/pic1.jpg" class="full" />
</div>
</div>
</div>`
As far as I can tell, the conflict is between these lines:
<script type="text/javascript" src="scripts/mootools.js"></script>
and
<script src="scripts/mootools-1.2.1-core-yc.js" type="text/javascript"></script>
<script src="scripts/mootools-1.2-more.js" type="text/javascript"></script>
in the head.
I'm using unmodified code from JD Gallery and SlimBox. Any help would be much appreciated!
The only problem I can see is an extra comma at the end of the gallery options:
var myGallery = new gallery($('myGallery'), {
...
showInfopane: false, <--- Right Here
});
At least Firefox and Chrome ignore the trailing comma, but it's a syntax error in Internet Explorer. After I fixed that, your code worked fine for me in Chrome, Firefox, and IE.
Like Anurag mentioned in the comments, you are including MooTools twice. It didn't cause any problems for me, but you can remove the scripts/mootools.js script, and it should still work.
In JQuery you can choose a new name for the JQuery function to avoid conflicts with other libraries, e.g. Prototype. Mootools might support something similar.
Alright, it's working now. Here's what's going on: I removed the extra comma as per Matthew Crumley's suggestion (+1). Per Anurag, I checked Chrome's developer tool (I completely forgot about that - working late = bad.) It didn't show any errors. Then I redownloaded the SlimBox files and tried the demo, which didn't work. Then I noticed that SlimBox had two folders with its SlimBox JS files: js and src. js is the correct folder with the correct library, src doesn't work for whatever reason. I changed the website to use the file from the js folder and it's now working.
Bottom line: No script conflict after all, SlimBox was just distributed in a weird way. Thank you everybody for your help!
I faced the same issue when I had to use two versions of jquery in the same page.
<script type='text/javascript'>
// This script prevent the conflict between older and newer versions of jquery
var $jq = jQuery.noConflict(true);
</script>
And then you can reference your different version of jquery by using something like this :
var $noborders = $jq('.noborders');
I hope something like this will solve your issue too.
