addEventListener和attachEvent的区别

<div class="container">

<div class="col-md-6 col-md-offset-3">

<h1>Vue demo</h1>

 

</div>

</div>

<script>

var h1=document.getElementsByTagName("h1")[0];

 

if(h1.addEventListener){

h1.addEventListener("click",fun1);

}else if(h1.attachEvent){

 

h1.attachEvent("onclick",fun2);

//h1.onclick=function(){alert(2)}

};

 

function fun1(){alert("1")};

function fun2(){alert("2")};

 

</script>

 

 

注意：1、attachEvent监听事件中,加on

2、attachEvent用于ie8以及更低的ie版本
