Jquery Overview
jQuery is a JavaScript library that simplifies AJAX, JSON and DOM manipulation, among other things. Recently an interfacing library was created (the jQuery UI) to standardise some common functionalities like date pick pop ups, buttons and alerts.
- Current API version API/1.4.2 (April 2010) Check the difference between this and the older version.
- Add on plugins made by jQuery community
- A mailing list is available for developers in the jQuery's community
- Use the compressed code for speed and the uncompressed for debugging (if working with plugins)
Which API to use?
For speed I recommend use Google's API jQuery library. Load JQuery and UI (need to use UI to animate colors):
<!-- JQUERY -->
<script type = 'text/javascript' src = 'https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js'></script>
<!-- JQUERY UI -->
<script src="http://www.google.com/jsapi"></script>
<script type="text/javascript">google.load("jqueryui", "1.5.2");</script>
