大家帮忙测试下，这个
Ready是否好用。谢谢
(function () {
window.Auto = {};
var readyBound = false,
readyList = [],
DOMContentLoaded
Auto = {
isReady: false,
_Ready: function () {
if (!Auto.isReady) {
if (!document.body) {
return setTimeout(Auto._Ready, 1);
}
Auto.isReady = true;
if (readyList) {
var fn, i = 0;
while ((fn = readyList[i++])) {
fn.call(document, Auto);
}
readyList = null;
}
}
},
