Javascript resize works in IE not FF

[eoin.haluch]

Hi,

I'm using javascript to set div sizes dependant on the size of the
window, it works in IE6 < but not IE 7 of FF. Any ideas?

<script language="JavaScript" type="text/javascript">
function getPageHeight() {
var myFooter =(document.body.scrollHeight > document.body.clientHeight)
? document.body.scrollHeight : document.body.clientHeight;
document.getElementById("sidebar").style.height = myFooter-175;
}
getPageHeight();
</script>
