帮帮忙看下为什么ie6不起作用

[ZJM2032]

这段代码是做下拉菜单用的,在ie7,8下都是可以的,在ie6下就不起作用,下拉不下来了不知道什么原因
stuHover = function() {
var cssRule;
var newSelector;
for (var i = 0; i < document.styleSheets.length; i++)
for (var x = 0; x < document.styleSheets[i].rules.length ; x++)
{
cssRule = document.styleSheets[i].rules[x];
//if (cssRule.selectorText.indexOf("LI:hover") != -1)
//{
//newSelector = cssRule.selectorText.replace(/LI:hover/gi, "LI.iehover");
//document.styleSheets[i].addRule(newSelector , cssRule.style.cssText);
//}
}
var getElm = document.getElementById("nav").getElementsByTagName("LI");
for (var i=0; i<getElm.length; i++) {
getElm[i].onmouseover=function() {
this.className+=" iehover";
}
getElm[i].onmouseout=function() {
this.className=this.className.replace(new RegExp(" iehover\\b"), "");
}
}
}
if (window.attachEvent) window.attachEvent("onload", stuHover);

检查一下document.styleSheets.length和
document.styleSheets[i].rules.length 的值，看看是多少？对不对？

还有html代码呢？

实在不行，可以考虑用jq，jq兼容性不错。
