jQuery Code

<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>setInterval(function() {$('#refreshdiv').load('divcontainer.html')}, 10000);</script>

divcontainer.html 

This is loading in the div #refreshdiv.

This example will load divcontainer.html in the div #refreshdiv and refresh the div after 10 seconds.
If you want to change the file to load replace divcontainer.html in the jquery code to the file name you want to use.
If you want to change the number of seconds, replace 10000 with the number to refresh(Must be in milliseconds).
