Need to find height of hidden div on page (set to display:none)

Answer 1

What I wound up having to do was this:

Using YUI 2, on page load, I found all elements of that given classname that were either set to display:none, or whose height and width was 0 (that's one way of measuring whether an element exists, or a parent is set to display:none). I then set that element to display:block. I then checked it's parent for the same thing and showed the parents until it finds a visible parent. Once highest display:none ancestor is set to display:block, I can measure my element.

Once all elements are measured I reset all of the elements back to display:none.
