attachEvent在IE6/7/8下添加同一个类型事件的多个handler执行倒序

如下，

<div id="d1" style="200px;height:200px;background:gold;"></div>
<script type="text/javascript">
	function addEvent(el, type, fn){
		if(el.addEventListener){
			el.addEventListener(type, fn, false);
		}else{
			el.attachEvent('on' + type, fn);
		}
	}
	var el = document.getElementById('d1');
	function handler1(){
		alert('test1');
	}
	function handler2(){
		alert('test2');
	}
	function handler3(){
		alert('test3');
	}
	function handler4(){
		alert('test4');
	}
	function handler5(){
		alert('test5');
	}
	addEvent(el, 'click', handler1);
	addEvent(el, 'click', handler2);
	addEvent(el, 'click', handler3);
	addEvent(el, 'click', handler4);
	addEvent(el, 'click', handler5);
</script>

以上，给div[id=d1]的click事件添加了5个handler。点击其，结果如下

IE6/7/8 ：无序(可多点几次试试)

IE9/Firefox/Safari/Chrome/Opera ：test1 -> test2 -> test3 -> test4 -> test5 顺序

点击一下黄色区域试试看
