Ok...I am officially bald now that I have pulled all my hair out trying to get this to work.

I have a java script menu that I have been using for years in IE. As this is used on and intranet, having it work on IE only has been ok. But now users are asking for it to work in Firefox/Mozilla. The menu uses a mouseover event to display a drop down menu. On IE the mouse over works, but in Firefox, when you hover over the link, the menu does not appear.

I have posted the code below. Can someone smarter than me take a look and tell me what I'm doing wrong?

Thanks in Advance...

Mike

On IE the mouse over works, but in Firefox, when you hover over the link, the menu does not appear.
Click to expand...

That's because IE is smart enough to work in quirksmode and FF is not. You will need to use a valid doctype and clean up your code. With a valid doctype IE does not work either.

Hope that helps!

Well... where to start. There were so many errors in the code, it just was too much hassle to list them all... so instead, I've just cut out all the support for older browsers (who uses NN4 now?), and tidied up the code generally. It's not 100%, but it looks good in FF, NN, and IE, and will do with a small amount of tweaking for Opera:

Code: 
<html>
<head>
	<style type="text/css">
		body  {
			background: #00009C;
			font-size: 10px;
			font-color: navy;
		}
		body, td, tr, th {
			font-family: Tahoma, sans-serif;
		}
		a {
			color: #FFFFFF;
			font-weight: bold;
			text-decoration: none;
		}
		a:hover {
			text-decoration: underline;
		}
		a:visited {
			color: #FFFFFF;
		}
		td {
			font-size: 10px;
			font-color: #DAE722;
		}
		th {
			font-size: 10px;
			font-color: #FFFFFF;
		}
	</style>

	<script type="text/javascript">
	<!--
		function wldInitialisePage() {
			DocLoaded = 'done' ;
			Pressed = false ;
		}

		var timer;

		function Show() {
			if (timer) clearTimeout(timer);
			for (menu=0; menu<Layer.length; menu++) {
				if(Layer[menu]) document.getElementById('L'+menu).style.visibility = "hidden";
			}
			for (i=0; i<arguments.length; i++) {
				menu = arguments[i];
				document.getElementById('L'+menu).style.visibility = "visible";
			}
		}

		function Hide() {
			timer = setTimeout("Show()", 500);
		}
	//-->
	</script>
