I'm using the following JQuery Popup code to make smooth popups: ( http://yensdesign.com/2008/09/how-to-create-a-stunning-and-smooth-popup-using-jquery/)

I was wondering how I can use use this to load external pages into the popup?

So instead of having a hidden <div> in the page, there would be some sort of empty <div (<div id='this'></div>).  The when I click a link, an external page would be loaded into this empty.

So it would function just as it does in the above tutorial, expect the popup content would be coming from an another page, not within the page
