for(var i=0; i<arr.length; i++){
var dd = arr[i];
var as = dd.getElementsByTagName("a");
for(var j=0; j<as.length; j++){
as[j].onclick = function(){doclickA(this);
var meenu = getObject("list1");
var mennu=getObject("fade")
meenu.style.display = "none";
mennu.style.display='none';
}
}
} 怎么循环var arr = [getObject("aaa0"), getObject("aaa1"), getObject("aaa2")];
aaa1....aaaN,怎么取到DIV里有几个aaa然后循环出几个getObject("aaa1")
把取到 id="items0"赋给arr数组，items后面的0递增的现在是写死的，如果在增加一个id="items3"就不会起作用
