Topic awaiting preservation: getting the height of a td

I've tried this... but it wont return a value unless I specify an attribute in the <TD>. I want it to dynamically grab the height, not the attribute value.

<td width="150" id="tdHeightGet">

...some code here

</td>

<script>
var daitem = document.getElementById("tdHeightGet").height;

alert(daitem);
</script>

Check in May 2005 - 20 lines JavaScript contest - Asteroids. We discussed about that kind of problem.

var daitem = document.getElementById("tdHeightGet").offsetHeight; // should work

Hope that helps,

Just a note. This usually has to happen after page load. So you have to fire it off of a page onload handler
