Load content of a div on another page
You just need to add a jquery selector after the url.
See: http://api.jquery.com/load/
Example straight from the API:
$('#result').load('ajax/test.html #container');
So what that does is it loads the #container element from the specified url.
Yes, see "Loading Page Fragments" on http://api.jquery.com/load/.
In short, you add the selector after the URL. For example:
$('#result').load('ajax/test.html #container');
