can anyone pls help me why FIREFOX displays 'reference to undefined property' message for this html page? It works fine in IE.
[code]
<html>
<head>
<title>Expandible row test in firefox</title>
<STYLE type="text/css">
.collapsed
{
DISPLAY: none;
}
</STYLE>
<script language="javascript" type="text/javascript">
//***collapsible rows
function outliner(evt) {
evt = (evt) ? evt : (window.event) ? window.event : "";
var oMe;
if (evt.srcElement) {
oMe = evt.srcElement;
} else if (evt.target) {
oMe = evt.target;
}
if (evt.srcElement) {
//for IE
var child = document.all[oMe.getAttribute("child",false)];
}
else {
//for Firefox
var child = document.getElementById[oMe.getAttribute("child",false)];
}
//get child element
//if child element exists, expand or collapse it.
if (null != child)
child.className = child.className == "collapsed" ? "expanded" : "collapsed";
}
function changepic(evt) {
evt = (evt) ? evt : (window.event) ? window.event : "";
var uMe;
if (evt.srcElement) {
uMe = evt.srcElement;
} else if (evt.target) {
uMe = evt.target;
}
var check = uMe.src.toLowerCase();
if (check.lastIndexOf("expand.gif") != -1)
{
uMe.src = "collapse.gif";
}
else
{
uMe.src = "expand.gif";
}
}
</script>
