相當著急的找了一早上，幸好有原來的代碼作為基礎，不害怕。
<script>
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 = -2;
var y = 140;
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 = y");
eval("document.all." + layerName + ".style.posLeft = x");
setTimeout("MoveLeftLayer('AdLayer1');", 20);
