[_] detect height of div

having problems detecting the height of a div with javascript.

if I have a div like

<div id="mydiv" style="width:100px;height:100px">

and I do:-

body onload="alert(document.getElementById("mydiv").style.height)"

it returns 100px even if I fill the div with a whole page of text. If I remove the style it returns blank.

I won't know how much content is in the div because it is dynamically generated.

(This only needs to work on IE 5.5+ for an intranet app, but mozilla support would be good)

any ideas?
