於addEventListener()和removeEventListener()
<div id= "div1 "> click me </div>
<script>
var fnClick=function(){
alert( "clicked! ");
};

var oDiv=document.getElementById( "div1 ");
alert( "aa ");
oDiv.addEventListener( "click ",fnClick,false);//出.
oDiv.removeEventListener( "click ",fnClick,false);
</script>

行addEventListener候出,不支持性或方法.

[解决办法]
addEventListener, removeEventListener are not supported in Internet Explorer. You can use attachEvent, detachEvent instead.
