为什么这个代码本地运行的时候没问题，放到网站上面就不动了呢？

郁闷，本地调试的时候正常，放到网站上面就固定不动了，是什么原因？？？

代码:

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 = 100;// 左侧广告距离页首高度
var diff = (document.body.scrollTop + y - document.all.AdLayer1.style.posTop)*.40;
var y = document.body.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 = 100;// 右侧广告距离页首高度
var diff = (document.body.scrollTop + y - document.all.AdLayer2.style.posTop)*.40;
var y = document.body.scrollTop + y - diff;
eval("document.all." + layerName + ".style.posTop = y");
eval("document.all." + layerName + ".style.posRight = x");
setTimeout("MoveRightLayer('AdLayer2');", 20);
}
document.write("<div id=AdLayer1 style='position: absolute;visibility:hidden;z-index:1'><iframe src=\"http:\/\/127.0.0.1\/gg\/left.html\" width=\"120\" height=\"270\" MARGINWIDTH=\"0\" MARGINHEIGHT=\"0\" HSPACE=\"0\" VSPACE=\"0\" FRAMEBORDER=\"0\" SCROLLING=\"no\"><\/iframe></div>"
+"<div id=AdLayer2 style='position: absolute;visibility:hidden;z-index:1'><iframe src=\"http:\/\/127.0.0.1\/gg\/right.html\" width=\"120\" height=\"270\" MARGINWIDTH=\"0\" MARGINHEIGHT=\"0\" HSPACE=\"0\" VSPACE=\"0\" FRAMEBORDER=\"0\" SCROLLING=\"no\"><\/iframe></div>");
initEcAd()
// JavaScript Document

 

没杀啊,可以显示的,就是不动

 

没有啊，这是我郁闷的地方
