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>

You are calling the ready function before the jQuery JavaScript is included. Reference jQuery first.

ReferenceError: "x" is not defined, The JavaScript exception "variable is not defined" occurs when there is a non-​existent variable referenced somewhere.

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.

[Solved] Uncaught ReferenceError : $ is not defined jQuery Error , [Fixed] Uncaught ReferenceError: $ is not defined. 1.

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>

Because all of these are built on top of JavaScript.


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.
