Uncaught TypeError: undefined is not a function on loading jquery-min.js

I got the same error from having two references to different versions of jQuery.

In my master page:

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>

And also on the page:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"> </script>

Assuming this problem still has not be resolved, a lot of individual files don't end their code with a semicolon. Most jQuery scripts end with (jQuery) and you need to have (jQuery);.

As separate files the script will load just fine but as one individual file you need the semicolons.

You might have to re-check the order in which you are merging the files, it should be something like:

1. jquery.min.js
2. jquery-ui.js
3. any third party plugins you loading
4. your custom JS

This solution worked for me

    ;(function($){
        // your code
    })(jQuery);

Move your code inside the closure and use $ instead of jQuery

I found the above solution in https://magento.stackexchange.com/questions/33348/uncaught-typeerror-undefined-is-not-a-function-when-using-a-jquery-plugin-in-ma
