我用js 在html 页面做了一个下拉菜单，别的浏览器都可以，但是火狐浏览器看不到。如何把下列js代码改为FireFox支持的?

在页面上的doExit写成doExit(event)
function doExit(e){
e =   e||event
var elm=e.relatedTarget||e.toElement;
eExit=event.toElement;
if (eMenu==null || eExit==null) return;
if (!eMenu.contains(eExit) && !eItem.contains(eExit)) noMenu();
}function doOver(){
if ("A"==event.srcElement.tagName.toUpperCase()) {
eItem=event.srcElement.parentElement;
eDesk=eItem.parentElement;
eMenu=document.all[eItem.id.replace('item','menu')];
if (eMenu && eMenu!=null) {eMenu.onmouseout=doExit;doMenu();}
else noMenu();}
}
写成
function doOver(e){           //页面上doOver(event)
e = event|| e
var obj = e.srcElement||e.target
if ("A"==obj.tagName.toUpperCase()) {
eItem=obj.parentElement;
eDesk=eItem.parentElement;
eMenu=document.all[eItem.id.replace('item','menu')];
if (eMenu && eMenu!=null) {eMenu.onmouseout=doExit;doMenu();}
else noMenu();}
}
无完整例子无法调试

没有例子无法调试。LS改的是正确的，不过肯定还是不能在FF上运行的。补充一点
倒数第三行使用document.all在FF中是不支持的，LZ看下最好是使用别有方式来获取控件
ie的event.srcElement在ff下是e.target
css的属性值可能需要指定单位
document.all最好用document.getElementById/getElementsByTagName/getElementsByName等标准的方法来代替parentElement看起来比较陌生，通常是写parentNode/childNodes的..
本人菜鸟一只,希望各位大哥、大姐多多帮忙，小妹在此谢过了！！关于html 页面代码我整理了一下,大家请看：

抱歉 menu.js 里有段代码没粘，本来以为没用的。function doHome(i){
switch (i) {
case 1 : window.external.AddFavorite('http://www.experexchange.com',document.title);break;
case 2 : window.external.AddChannel('http://www.experexchange.com');break;
default : event.srcElement.style.behavior='url(#default#homepage)';event.srcElement.setHomePage('http://www.experexchange.com');break;}
return false;
}function doSel(){
var o=event.srcElement;
if ('select'!=o.tagName.toLowerCase()) return;
var s=o.options[o.selectedIndex].value;
o.selectedIndex=0;
if (s!='1') self.location=s;
}function doWin(l,a,b){
w=window.open(l,'dhtmlet','toolbar=0');
var winx=Math.ceil((window.screen.width-a)/2);
var winy=Math.ceil((window.screen.height-b)/2);
w.resizeTo(a,b);
w.moveTo(winx,winy);
w.focus();想了想还是把整个文件贴出来吧，方便大家调试。这个在ie里面是没问题的<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
