这是用Javascript写的跟随鼠标的图形特效；好玩！

 <script language="JavaScript">

var newtop=0

var newleft=0

if (navigator.appName == "Netscape") {

layerStyleRef="layer.";

layerRef="document.layers";

}

else

layerRef="document.all";

styleSwitch=".style";

}

 

function doMouseMove() {

 

layerName = 'iit'

 

eval('var curElement='+layerRef+'["'+layerName+'"]')

eval(layerRef+'["'+layerName+'"]'+styleSwitch+'.visibility="hidden"')

eval('curElement'+styleSwitch+'.visibility="visible"')

eval('newleft=document.body.clientWidth-curElement'+styleSwitch+'.pixelWidth')

eval('newtop=document.body.clientHeight-curElement'+styleSwitch+'.pixelHeight')

eval('width=curElement'+styleSwitch+'.width')

width=parseInt(width)

height=parseInt(height)

if (event.clientX > (document.body.clientWidth - 5 - width))

{
