本文实例讲述了js实现鼠标触发图片抖动效果的方法。分享给大家供大家参考。具体实现方法如下：
复制代码 代码如下:<html>
<head>
<title>鼠标触发图片抖动效果</title>
<style>
.shakeimage{
position:relative
}
</style>
<script language="JavaScript1.2">
//configure shake degree (where larger # equals greater shake)
var rector=3
///////DONE EDITTING///////////
var stopit=0
var a=1
function init(which){
stopit=0
shake=which
shake.style.left=0
shake.style.top=0
}
function rattleimage(){
if ((!document.all&&!document.getElementById)||stopit==1)
return
if (a==1){
shake.style.top=parseInt(shake.style.top)+rector
}
else if (a==2){
shake.style.left=parseInt(shake.style.left)+rector
}
else if (a==3){
shake.style.top=parseInt(shake.style.top)-rector
}
else{
shake.style.left=parseInt(shake.style.left)-rector
}
if (a<4)
a++
else
a=1
setTimeout("rattleimage()",50)
}
function stoprattle(which){
stopit=1
which.style.left=0
which.style.top=0
}
</script>
</head>
<body bgcolor="#F7F7F7">
<p align="center">
<img src=http://www.jb51.netimages/skinslogo.gif onMouseover="init(this);rattleimage()" onMouseout="stoprattle(this)">
<br>
鼠标移动上来看效果！</p>
</body>
</html>
