rette menu så den også kan bruges i linux og på mac

Hvordan får jeg dette menu script til at virke, så både windows,linux og mac ejere kan bruge undermenuerne.

Her er scriptet.

if(typeof(loc)=="undefined"||loc==""){var loc="";if(document.body&&document.body.innerHTML){var tt=document.body.innerHTML.toLowerCase();var last=tt.indexOf("meny.js\"");if(last>0){var first=tt.lastIndexOf("\"",last);if(first>0&&first<last)loc=document.body.innerHTML.substr(first+1,last-first-1);}}}

var bd=0
document.write("<style type=\"text/css\">");
document.write("\n<!--\n");
document.write(".meny_menu {z-index:999;border-color:#000000;border-style:solid;border-width:"+bd+"px 0px "+bd+"px 0px;background-color:#a4a4a4;position:absolute;left:0px;top:0px;visibility:hidden;}");
document.write(".meny_plain, a.meny_plain:link, a.meny_plain:visited{text-align:left;background-color:#a4a4a4;color:#4265ff;text-decoration:none;border-color:#000000;border-style:solid;border-width:0px "+bd+"px 0px "+bd+"px;padding:2px 0px 2px 0px;cursor:hand;display:block;font-size:10pt;font-family:Arial, Helvetica, sans-serif;}");
document.write("a.meny_plain:hover, a.meny_plain:active{background-color:#e1e1e1;color:#000000;text-decoration:none;border-color:#000000;border-style:solid;border-width:0px "+bd+"px 0px "+bd+"px;padding:2px 0px 2px 0px;cursor:hand;display:block;font-size:10pt;font-family:Arial, Helvetica, sans-serif;}");
document.write("\n-->\n");
document.write("</style>");
