 Javascript:

    window.onload=function menuFix() {
    var strUrl,strHref;
    var Navs=document.getElementById("nav1").getElementsByTagName("a");     //nav1是ul 的id                    
    // 如果链接没有参数,或者URL链接中不存在我们要获取的参数,则返回数组中的序号
    strUrl=location.href.substring(location.href.lastIndexOf("/")+1);//取得URL页面名称
    for (var i = 0; i < Navs.length; i++) {            
        strHref=Navs[i].getAttribute("href").substring(Navs[i].getAttribute("href").lastIndexOf('/')+1);    
        ///在IE6,IE7中strHref获得的是全路径,而在IE8和ff中获得的是页面名称,为了兼容,需要将它的字符串进行拆分/
        if(strUrl==strHref){//高亮当前菜单
            Navs[i].className = "current"        
        }
        else{
            Navs[i].onmouseover=function() {
                this.className+=(this.className.length>0? " ": "") + "over";
            }
            Navs[i].onmouseout=function() {
                this.className=this.className.replace(new RegExp("( ?|^)over\\b"),"");
            }  
        }
