Another simpler one
<img id="win" style='position:relative' src="/UploadPic/2008-9/2008962512241.jpg">
<br /><br />
<button onclick="zd()">振动</button>
<script >
function zd(u){
var a=['top','left'],b=0;
u=setInterval(function(){
document.getElementById('win').style[a[b%2]]=(b++)%4<2?0:4;
if(b>15){clearInterval(u);b=0}
},32)
}
</script>The above is the entire content of this article, I hope you all like it.
