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'm trying to understand why I can't load captureMouvement.js whereas I can load verifieFormulaire.js. Both of them are stored in the same file as my PHP file. I need to use PHP because I really want that page being dynamic.
I'm also running this site on localhost.
Fact : I could call the script when the page was a HTML file.
I've tried to call the script that is already stored on another server. It did not worked. I also tried to move down to , it did not worked either.
I also tried to call the script using ;?> but this failed too
<head>
<title>Projet</title>
<link href="projet.css" type="text/css" rel="stylesheet" title="projet.css" />
<meta charset="UTF-8">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src ="https://tp-ssh1.dep-informatique.u-psud.fr/~mpetit4/verifieFormulaire.js"></script>
<script src ="https://tp-ssh1.dep-informatique.u-psud.fr/~mpetit4/captureMouvement.js"></script>
<script src ="https://tp-ssh2.dep-informatique.u-psud.fr/~mpetit4/captureMouvement.js"></script>
<script src ="verifieFormulaire.js"></script>
<?php echo '<script src ="projetweb/captureMouvement.js"></script>';?>
</head>
This should call captureMouvement.js, either from local file or from tp-ssh1.dep-informatique.u-psud.fr.
I opened google chrome, so I could check for javascript console. I got this error message : net::ERR_ABORTED 404 (Not Found)
However, I did not get this error for verifieFormulaire.js
Please, help me.
If the .js files are in the same directory as the HTML page (it doesn't matter if it's a PHP page on your server; it's an HTML page from the browser's perspective), then using no path is correct. So remove the extra script tags and the path on them, and there's no need to use PHP to output a static string:
<meta charset="UTF-8">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src ="https://tp-ssh1.dep-informatique.u-psud.fr/~mpetit4/verifieFormulaire.js"></script>
<script src ="https://tp-ssh1.dep-informatique.u-psud.fr/~mpetit4/captureMouvement.js"></script>
<script src ="https://tp-ssh2.dep-informatique.u-psud.fr/~mpetit4/captureMouvement.js"></script>
<script src ="verifieFormulaire.js"></script>
<?php echo '</script>';?>
Those changes give you this:
<meta charset="UTF-8">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src ="captureMouvement.js"></script>
<script src ="verifieFormulaire.js"></script>
If that works for verifieFormulaire.js but not for captureMouvement.js, then there are really only a few possible reasons:
There's a problem with the permissions on captureMouvement.js; make sure they match verifieFormulaire.js.
There's a typo in the name (perhaps you're using a case-sensitive file system and the filename is capturemouvement.js or in some other way subtly different).
captureMouvement.js isn't in the same directory.
captureMouvement.js is getting loaded, but failing to parse/run because of a syntax error. Check your web console for errors. (No, you said you get a 404 for it.)
I've founded this article but I don't know where to add this code:
$(document).ready(function(){
$(".showDescriptionTextbox").val($(".Product").val());//to initialize
$(".showDescriptionDiv").text($(".Product").val());//to initialize
$(".Product").change(function(){
$(".showDescriptionTextbox").val($(".Product").val());
$(".showDescriptionDiv").text($(".Product").val());
});
});
I've file jquery-1.11.3.min.js, jquery-1.10.2.min.js.
Should I edit one of both file with above code? Please give me a hint.
I want to execute query SQL by clicking the select option that I know it's just possible using jquery/ajax/js, but I'm still newbie.
I've file jquery-1.11.3.min.js, jquery-1.10.2.min.js. Both are jquery library file with different version. Only one should be included.
In your case the code snippet which you have shared can be included in a separate js file. Like this
nameOfYourJSFile.js
$(document).ready(function(){
$(".showDescriptionTextbox").val($(".Product").val());//to initialize
$(".showDescriptionDiv").text($(".Product").val());//to initialize
$(".Product").change(function(){
$(".showDescriptionTextbox").val($(".Product").val());
$(".showDescriptionDiv").text($(".Product").val());
});
});
Include the file in your main html file. Add the scripts near the bottom of the page.
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="style.css">
</head>
<body>
<h1>Hello Plunker!</h1>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="nameOfYourJSScript.js"></script>
</body>
</html>
DEMO
If the file is included in the bottom , there is no need to use document.ready function
Add your code BELOW the <script src="jquery-1.11.3.min.js"></script>
So, JQuery will be loaded and can be used
I'm trying to use an external js file to use in my pyramid project.
I found this solution but i can't seem to get it work.
The js files i want to include are in C:\env\uza\uza\static\js
project name = uza.
In my template i use this to call the script:
<script type="text/js" src="${request.static_url('uza:static/js/fabtabulous.js')}" />
<script type="text/js" src="${request.static_url('uza:static/js/tablekit.js')}" />
my init.py looks like this:
config.add_static_view('static', 'static', cache_max_age=3600)
When i navigate to the page in my browser it just gives me the pyramid sidebar in raw html code. I know it's a stupid mistake i made somewhere but i can't seem to find it. Is annyone able to help me with this.
EDIT:
I uploaded a pdf to give a better understanding of the problem i'm having.
ps: there are no errors in console.
https://dl.dropboxusercontent.com/u/6752022/problem.pdf
EDIT:
I made a new project using the sqlalchemy scaffold.
The changes I made are:
- include this line in the mytemplate.pt
<script type="text/js" src="${request.static_url('javascript:static/js/tette.js')}" />
<input type="button" onclick="popup()" value="Click Me!">
- i didn't change annything else because i don't think anny other changes need to be made in the scaffold.
my tette.js file looks like this:
function popup() {
alert("Hello World")
}
This is the output i have before including the js file. (deleted a few divs)
And this is after.
what am I doing wrong ? thanks in advance.
Can you back it out to a point to where the pyramid sidebar looks and works correctly, and isn't raw HTML?
Your init.py line looks correct. Then in your templates you can get at whatever is in the 'static' folder like so:
<link rel="stylesheet" href="${request.static_url('myproject:static/style.css')}">
<!--[if lte IE 6]>
<link rel="stylesheet" href="${request.static_url('myproject:static/ie6.css')}" type="text/css" media="screen"
charset="utf-8"/>
<![endif]-->
<script type="text/javascript"
src="${request.static_url('myproject:static/tinymce/jscripts/tiny_mce/tiny_mce.js')}"></script>
it's as Peter Tirrell says.
I didn't say the type was javascript.
I have a linux webserver that has /var/www configured in the Apache2.conf file as the DocumentRoot. Next I have my jquery core file located at /var/www/js/jQuery_v1.4.2.js (a central location for all my websites to access.
The .php index file is located at /var/www/AOI/aoiparse.php, where the aoifunctions.js file is also located. My <head> tag looks as follows:
<script type='text/javascript' scr='/js/jQuery_v1.4.2.js'></script>
<script type='text/javascript' scr='aoifunctions.js'></script>
my aoifunctions.js file has the following in it in order to verify that the script link works:
$(document).ready(function(){
alert("hello");
});
My problem is that I cannot get the alert() to work. I'm not getting an error message so I do not know where the problem is.
You can try <script type='text/javascript' src='../js/jQuery_v1.4.2.js'></script>
(The attribute is src, not scr, plus your path was incorrect)
put the jquery file in /var/www/AOI/js/ and then
remove the first /
<script type='text/javascript' src='js/jQuery_v1.4.2.js'></script>
so it lies in a subdirectory to your main page
or use this if you want to leave it where it is:
<script type='text/javascript' src='../js/jQuery_v1.4.2.js'></script>
You misspelled "src" in your <script> tags. It's short for SouRCe.
<script type='text/javascript' src='/js/jQuery_v1.4.2.js'></script>
<script type='text/javascript' src='aoifunctions.js'></script>
If you used Firebug you'd have been able to easily tell that the scripts weren't loaded.
