window.onload = function(){
var oTab = document.getElementById("tabs");
var oUl = oTab.getElementsByTagName("ul")[0];
var oLis = oUl.getElementsByTagName("li");
var oDivs= oTab.getElementsByTagName("div");
for(var i= 0,len = oLis.length;i<len;i++){
oLis[i].index = i;
oLis[i].onmousemove = function() {
for(var n= 0;n<len;n++){
oLis[n].className = "";
oDivs[n].className = "hide";
}
this.className = "on";
oDivs[this.index].className = "";
}
}
}
////////
for(var n= 0;n<len;n++){
oLis[n].className = "";
oDivs[n].className = "hide";
}
这个循环是什么意思?
