js运动 为什么返回的时候老是抖动？
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>speed</title>
<style type="text/css">
div{width: 100px;height: 50px;background: red;margin: 10px}
</style>
<script type="text/javascript">
window.onload=function()
{
var aDiv=document.getElementsByTagName('div')
for(var i=0;i<aDiv.length;i++)
{ aDiv[i].timer=null
aDiv[i].onmouseover=function()
{
startMove(this,400)
}
aDiv[i].onmouseout=function()
{
startMove(this,100)
}
}
}
var timer=null;
function startMove(obj,iTarget)
{
clearInterval(timer)
obj.timer=setInterval(function()
{
var speed=(iTarget-obj.offsetWidth)/6;
speed=speed>0?Math.ceil(speed):Math.floor(speed)
if(obj.offsetWitdh==iTarget)
{
clearInterval(obj.timer)
}
else
{
obj.style.width=obj.offsetWidth+speed+'px'
}
},30)
}
</script>
</head>
<body>
<div></div>
<div></div>
<div></div>
</body>

最开始的也要改成clearInterval(obj.timer)；还有if(obj.offsetWitdh==iTarget)这里width写错了
