Browser specific JavaScript error

[SwapnilD]

I'm having a problem with submenu list. In my website I have code which populate a list of submenus onmouseover it works fine for IE but doesn't work for Mozilla and Chrome. Below is the code that.

<style>
.menu { 
color: #000000; font-family: arial; font-size: 11px; line-height: 12px;
 padding-top: 3px;
position: absolute; visibility: hidden; width: 175px; zindex: 99; 
}
.unnamed1 {  font-family: Verdana, Arial, Helvetica, sans-serif; font-size: xx-small}
.txtheader1 {
font-family: Verdana; font-size: 11px}
</style>
<script language="Javascript" src="fnc_menu.js"></script>
<script language=javascript>

Look at your code:

var isMacIE = ( (navigator.userAgent.indexOf("IE 4") > -1) && (navigator.userAgent.indexOf("Mac")  > -1) );
browserName = navigator.appName;           
browserVer = parseInt(navigator.appVersion); 
if (browserName == "Netscape" && browserVer >= 4)version = "n4";
else if (browserName == "Microsoft Internet Explorer" && browserVer >= 4) version = "e4";
 
    if (version == "n4" || version == "e4" && !isMacIE)     
    {         

It's old and ancient. It's checking for IE4+ and Netscape 4+ and ignoring everyone else! Get rid of the browser sniffing and there's a chance it may work in other browsers.
