ommouseover绑定两个同名的函数为什么第一个函数就不执行了？代码如下
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style type="text/css">
ul,li{
list-style: none;
}
ul li{
width: 200px;
height: 100px;
background: red;
margin-bottom: 20px;
border: 4px solid #000;
font-size: 8px;
}
</style>
<script type="text/javascript">
window.onload=function(){
var aLi=document.getElementsByTagName("li");
for (var i= 0; i<aLi.length;i++) {
aLi[i].timer=null;
aLi[i].onmouseover=function(){
startMove(this,400,'width');
startMove(this,200,'height');
}
aLi[i].onmouseout=function(){
startMove(this,200,'width');
startMove(this,100,'height');
}
}
}
function startMove(obj,iTarget,attr){
clearInterval(obj.timer);
obj.timer=setInterval(function(){
var speed=(iTarget-parseInt(getStyle(obj,attr)))/10;
speed=speed>0?Math.ceil(speed):Math.floor(speed);
if(parseInt(getStyle(obj,attr))==iTarget){clearInterval(obj.timer);}
else{obj.style[attr]=parseInt(getStyle(obj,attr))+speed+'px';
}
},20);
}
function getStyle(obj,attr){
if(obj.currentStyle){
return obj.currentStyle[attr];
}
else{
return getComputedStyle(obj,false)[attr];
}
}
</script>
</head>
<body>
<ul>
<li></li>
<li></li>
<li></li>
</ul>
</body>
</html>这样为什么就跳过了第一个函数直接执行第二个函数了？
