How can I get a parent window's height from within iFrame using jQuery?

Question

Within an iFrame, we need to get the parent's window/document height.

Is there a way to get this using jQuery?

I know we can use $(document).height() to get a page's height. I just can't figure out how to get the parent's value from within the iFrame.

Answer 1

jQuery is not needed.

parent.document.body.clientHeight

That works for me with IE7 and FF3.

Answer 2

In jQuery you can do

$(parent.window).width();
