哪位兄弟帮我看看,这个页面右边的的快捷彩单为什么会无限向下和无限向右
http://qzhuamei.bjsx14.host.

   <script type="text/javascript" language="javascript">
   
  function scrollImg2(){
    var posX2,posY2;
    if (window.innerHeight) {
        posX2 = window.pageXOffset;
        posY2 = window.pageYOffset;
    }
    else if (document.documentElement && document.documentElement.scrollTop) {
        posX2 = document.documentElement.scrollLeft;
        posY2 = document.documentElement.scrollTop;
    }
    else if (document.body) {
        posX2 = document.body.scrollLeft;
        posY2 = document.body.scrollTop;
    }
    var ad=document.getElementById("ad2");
    ad.style.top=(posY2+122)+"px";
    ad.style.left=(posX2+940)+"px";
    setTimeout("scrollImg2()",200);
}</script>
