window.wby||(window['wby']={});
wby.VERSION =”1.0.1″;
//DOM装载完毕
wby.dom={
onload:function(c) {
if (window.addEventListener)
window.addEventListener(“load”, c, false);
else if (window.attachEvent)
window.attachEvent(“onload”, c);
else {
var d = window["onload"];
window["onload"] = d != f ? this.ca( [ c, d ]) : c
}
},
ca:function(a) {
return function() {
for ( var b = 0; b < a.length; b++)
a[b]()
}
}
}
wby.ready=wby.dom.onload; //DOM准备就绪

在使用的时候只需要如下:

wby.ready(function(){
//你的代码

});

为啥用了一年多呢…
