在页面上加了对联广告后发现不滚动，找了n久才发现是这句导致不滚动的，可是如果去掉的话对于用div+css开发的网站来说又是灾难要另外找解决办法，应该是js里有代码不符合w3c的标准
找了资料才知道是document.body不符合标准，换成document.documentelement就可以了，汗，纪念一下自己浪费的时间

以下为JS原文件,只要在首页调用就OK了。
function initEcAd() {
document.all.AdLayer1.style.posTop = -200;
document.all.AdLayer1.style.visibility = 'visible'
document.all.AdLayer2.style.posTop = -200;
document.all.AdLayer2.style.visibility = 'visible'
MoveLeftLayer('AdLayer1');
MoveRightLayer('AdLayer2');
}
function MoveLeftLayer(layerName) {
var x = 5;
var y = 84;// 左侧广告距离页首高度
var diff = (document.documentElement.scrollTop + y - document.all.AdLayer1.style.posTop)*.40;
var y = document.documentElement.scrollTop + y - diff;
eval("document.all." + layerName + ".style.posTop = parseInt(y)");
eval("document.all." + layerName + ".style.posLeft = x");
setTimeout("MoveLeftLayer('AdLayer1');", 20);
}
function MoveRightLayer(layerName) {
var x = 5;
var y = 84;// 右侧广告距离页首高度
var diff = (document.documentElement.scrollTop + y - document.all.AdLayer2.style.posTop)*.40;
var y = document.documentElement.scrollTop + y - diff;
eval("document.all." + layerName + ".style.posTop = y");
eval("document.all." + layerName + ".style.posRight = x");
setTimeout("MoveRightLayer('AdLayer2');", 20);
}
