The problem is likely that you are missing jQuery. The example assumes you have a local copy, which you probably don't. Switch this line:
<script type="text/javascript" src="jquery-1.6.2.min.js"></script> to this: <script type="text/javascript" src= "http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js";></script> Also, depending on your server settings, you may need to add headers to the getData.php file. If the above change doesn't fix it for you, add these lines to getData.php before the "echo $string;" line: header('Cache-Control: no-cache, must-revalidate'); header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); header('Content-type: application/json'); The first two prevent the browser from caching the result and are not strictly necessary for this to work, but you will want them if the data is likely to change over time. The third line tells the server and browser that this is json, not HTML, and to interpret it appropriately.
