js浮动QQ代码，上下浮动！

新建js文件qq.js，代码如下：

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("LeftAd").style.top=parseInt(document.getElementById("LeftAd").style.top)+percent+"px";

lastScrollY=lastScrollY+percent;

}



suspendcode12="<div id=LeftAd style='background:url(qq.png);text-align:center;font-size:12px;line-height:150%;width:88px;height:183px;left:8px;position:relative;top:3px;'><div style='height:50px'></div><a target=blank href=http://wpa.qq.com/msgrd?V=1&Uin=523993703&Site=www.apsw8.com&Menu=yes><img border='0' SRC=http://wpa.qq.com/pa?p=1:523993703:4 alt='online' style='font-family:Arial'>523993703</a><br/><a target=blank href=http://wpa.qq.com/msgrd?V=1&Uin=523993703&Site=www.apsw8.com&Menu=yes><img border='0' SRC=http://wpa.qq.com/pa?p=1:523993703:4 alt='online'>523993703</a><br/><a target=blank href=http://wpa.qq.com/msgrd?V=1&Uin=523993703&Site=www.apsw8.com&Menu=yes><img border='0' SRC=http://wpa.qq.com/pa?p=1:1125690697:4 alt='online'>523993703</a></div>"

document.write(suspendcode12);

window.setInterval("heartBeat()",1);

function ClosedivLeft()

{

LeftAd.style.visibility="hidden";

}

红色是背景图片，

最后在body里加入<script src="qq.js" type="text/javascript"></script>，注意路径哦！也可以加入层，<div id="Layer2" style="position:absolute; left:909px; top:278px; width:96px; height:264px; z-index:2">

<script src="qq.js" type="text/javascript"></script></div>

代码很方便，有问题留言！
