Script to pull content from differnt URL

Is the a javascript that can pull content from a different URL that the current one? I would like to have a java popout that pulls some info from another page, but I don't want to leave the current page to have the user view it. It needs to be pulled from that other page.

Is the other page in the same domain as the current one? If not, it's not possible because of cross-domain restriction.

Yes, it is another page on my site, in the same domain.

Look into AJAX (http://www.w3schools.com/ajax/default.asp).
