本文实例讲述了js鼠标滑过图片震动特效的方法。分享给大家供大家参考。具体实现方法如下：
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>鼠标滑过 图片震动效果</title>
<STYLE>.shakeimage {
POSITION: relative
}
</STYLE>
</head>
<body>
<SCRIPT language=JavaScript1.2>
<!--
var rector=3
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>
<img class="shakeimage" onMouseOver="init(this);rattleimage()" onMouseOut="stoprattle(this)" src="/images/csrcode.ico" border="0" style="cursor:pointer;"/>
<img class="shakeimage" onmouseover="init(this);rattleimage()" onmouseout="stoprattle(this)" src="/images/changshi.ico" border="0" style="cursor:pointer;"/>
