使图片局部放大的特效（不过效果不太好）

<div style="width: 200px; height: 200px; z-index:

1; overflow: hidden; position: relative;" id="panl">

<img onclick="zoom();" id="img" border="0" src="http://www.webjx.com/img/200406301.jpg" width="173" height="232" style="left: 0; position: absolute; top: 0;"></div>

<script type="text/javascript">

<!--//more javascript http://www.webjx.com

var ZOOM=1.5

img.style.zoom=1;

function zoom(){

var divW=parseFloat(panl.style.width),divH=parseFloat(panl.style.height);

var x=event.offsetX*img.style.zoom*ZOOM;

var y=event.offsetY*img.style.zoom*ZOOM;

img.style.zoom*=ZOOM;

img.style.left=divW/2-x;

img.style.top=divH/2-y;

}

//-->

</script>
