How to load url into xpages

My requirement is to load a website (say www.xyz.com) into a part of the xpage, say a panel.

I am aware of loading urls into div tags using Ajax.

But I dont see an onload sort of event that would take client side javascript to do the same.

Also innerHTML (say getComponent(“id”).innerHTML ) property is not working with server side javascript.

Can any one please help me with this issue.

Thanks in advance
