我用的一个两侧图片可以浮动的代码,但显示5分钟左右就消失了,如何让他一直在网页上哪??以下是代码,
<script language="JavaScript" type="text/javascript">
lastScrollY=0;
function heartBeat(){
var diffY;
if (document.documentElement && document.documentElement.scrollTop)
diffY = document.documentElement.scrollTop;
else if (document.body)
diffY = document.body.scrollTop
else
{/*Netscape stuff*/}

//alert(diffY);
percent=.1*(diffY-lastScrollY);
if(percent>0)percent=Math.ceil(percent);
else percent=Math.floor(percent);
document.getElementById("lovexin12").style.top=parseInt(document.getElementById

("lovexin12").style.top)+percent+"px";

document.getElementById("lovexin13").style.top=parseInt(document.getElementById

("lovexin13").style.top)+percent+"px";

document.getElementById("lovexin14").style.top=pars

左栏浮动广告
