Responsive parallax effect missing arguments [duplicate]

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

Bootstrap tooltip not working though tried answers from stackoverflow

I tried all the solutions mentioned in stackoverflow and nothing works for me.
Head section as
<script src="js/bootstrap.js"></script>
<script type='text/javascript'>
$('[data-toggle="tooltip"]').tooltip();
</script>
and in html
<div class="odd-row">
<strong>10, 000</strong>
Datapoints
<i class="fa fa-plus-circle"></i>
</div>
in the bottom of the page (for performance reason) I included the other files
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="js/jQuery.js"> </script>
<script type="text/javascript" src="js/retina.js"></script>
Still the tooltip is not working!! Please help me.

You code is works for me.
Probably something wrong with structure of your html or some error in other part of JS.
Also you can try to put your code in document ready function.
$( document ).ready(function() {
$('[data-toggle="tooltip"]').tooltip();
});
Is this what you want? Try demo: http://jsfiddle.net/jdbNa/

For bootstrap you have to put jquery before you put bootstrap.js; so if you're putting bootstrap.js in the header you have to put the jquery.js before it.
Have you tried putting everything on the bottom before the closing body tag? maybe that would work. (I'm on stackoverflow looking for a tooltip solution myself to an issue I'm having)
Maybe try putting bootstrap.js after jquery.min.js, then below the retina.js, put your script to activate the tooltips.

Does jQuery have to be written in the <script> tags in HTML?

I'm learning jQuery, and I'm running into a small problem. jQuery code works when I put it directly in my tags in my HTML, but when I import it from a different file, nothing happens. These are my script tags in HTML:
<script type="text/javascript" src="scripts/jquery-1.10.2.js"></script>
<script type="text/javascript" src="scripts/test.js"></script> <!--This is my jQuery code-->
test.js contains the following code:
$(document).ready(function(){
console.log("Hello");
});
When the page loads, the console is empty. However, when I paste the following code as so, in my html document, everything works fine.
<script>
$(document).ready(function(){
console.log("Hello");
});
</script>

Do you really have a folder named scripts in the folder where your HTML files exist? Otherwise try changing this src="scripts/jquery-1.10.2.js" to probably this: src="/scripts/jquery-1.10.2.js"
You can check by browsing to http://yoururl/scripts/jquery-1.10.2.js, the Jquery code should show up. If it's not there, you have to make sure that you include the right folder/file.

Yes.You will be able to push your scripts in 2 ways::
1-push your scripts in tag like>>
<script>$(document).ready(function(){alert("Welcome Dear");});</script>
2-push your inline scripts with attributes like>>
<button type='button' onclick="$(this).hide()">Hide Me</button>

make sure that the scripts folder contain test.js make sure that the extension is correct ..sometimes I make the same same mistake, instead of test.js i save it as test.js.txt

Try putting
<script type="text/javascript" src="scripts/jquery-1.10.2.js"></script>
in the body rather than the head.

Importing JS file with AJAX does not work

I had some JavaScript code which was working but when I tried to put it into its own file, it stopped working :)
Here is the url I use:
http://www.comehike.com/hikes/javascript_library.js
Any idea why now it doesn't work? To test that it is working, try hitting this url to see if the google map shows up like it would if the JS was on the page.
http://www.comehike.com/hikes/hike_carpool.php?hike_id=125
Thanks,

<script type="text/javascript"
src="http://maps.google.com/maps/api/js?sensor=true">
</script>
<SCRIPT LANGUAGE="JavaScript" SRC="javascript_library.js"> </SCRIPT>
place the google map api before your javascript_library.js (aka your map scripts)
and remove the script tag from your javascript_library.js

Don't put HTML into your JavaScript files.
<script type="text/javascript">
