接上篇，其它方法：
一、在IE中还可以在onreadystatechange事件里进行判断

这里有Jesse Skinner写了一段独立的脚本函数来解决各种浏览器的onload问题，。

代码如下:
/*
* (c)2006 Jesse Skinner/Dean Edwards/Matthias Miller/John Resig
* Special thanks to Dan Webb's domready.js Prototype extension
* and Simon Willison's addLoadEvent
*
* For more info, see:
* http://www.thefutureoftheweb.com/blog/adddomloadevent
* http://dean.edwards.name/weblog/2006/06/again/
* http://www.vivabit.com/bollocks/2006/06/21/a-dom-ready-extension-for-prototype
* http://simon.incutio.com/archive/2004/05/26/addLoadEvent
*
*
* To use: call addDOMLoadEvent one or more times with functions, ie:
*
* function something() {
* // do something
* }
* addDOMLoadEvent(something);
*
* addDOMLoadEvent(function() {
* // do other stuff
* });
*
*/

addDOMLoadEvent = (function(){
// create event function stack
var load_events = [],
load_timer,
script,
done,
exec,
old_onload,
init = function () {
done = true;

// kill the timer
clearInterval(load_timer);

// execute each function in the stack in the order they were added
while (exec = load_events.shift())
exec();

if (script) script.onreadystatechange = '';
};

return function (func) {
// if the init function was already ran, just run this function now and stop
if (done) return func();

if (!load_events[0]) {
// for Mozilla/Opera9
if (document.addEventListener)
document.addEventListener("DOMContentLoaded", init, false);

// for Internet Explorer

/*@if (@_win32)
