You have not included jquery in your file.

Something like this:

<script src=http://code.jquery.com/jquery-latest.min.js type=text/javascript></script>

Or if you have it already in your source files, include it from there.

You need to add jQuery in order to use jQuery, see how to use jQuery

<script src=http://code.jquery.com/jquery-latest.min.js type=text/javascript></script>
