DIV height

[nibbcnoble]

I'm trying to find out what a div's height is. The div will be repeated and the height will vary, the problem is that I cant just use

document.getElementbyId(blah).style.height

because I've purposely cut off the bottom part of the div to be revealed via a separate javascript function. I want the javascript function to slide open the box revealing the rest of the text in the box, but I need to know how far to open it, or basically tell the function when to stop making the box bigger.

Basically, is there a way with the HTML DOM to extract a number for what a
auto height would be for a DIV?

any help would be much abliged.

offsetHeight

A cross browser (non W3C DOM) property that returns the height of the element, including borders and padding if any, but not margins. In IE6, if a validdoctype is not specified, margins/padding are NOT included in the returned value.

I just decided that the best way is that each box will have to have its height specified. Not the best way to do it... adds a lot of work, but its better than the incompatible options which are available.
