cross-domain request jquery

I need to create some JavaScript that does a cross-domain request.

The script must request a desired page and display it on the screen.

Need to do as well as this realised on facebook at开发者_运维技巧 display iframe application. How create this? Prease to demonstrate or give link on tutorial.

Thanks.

I'd suggest looking at JSONP and $.getJSON() There are lots of answers on this subject.

There are multiple ways of doing this, and your question states no specifics. It also contains horrible grammar that I attempted to edit but could still not fully understand. Please be more specific. Edit your questions if you wish to receive better answers than this one.
