I can't understand why need this line:


<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/jquery-ui.min.js"></script>

jQuery is a fast, small, and feature-rich JavaScript library.
jQuery UI is a curated set of user interface interactions, effects, widgets, and themes built on top of the jQuery JavaScript Library.
So, if you want to use some UI effects (accordion, autocomplete, datepicker,...) you need to use jQuery UI library.
