[求助]帮助小弟怎样实现这个功能
我想在网页上实现动态对联效果。在HTML中加入下列代码：以下代码加入<body>区域
<SCRIPT LANGUAGE="JavaScript">
<!--
//more javascript from http://3lian.com
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 = 340;
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 = 340;
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＇><img src="d:/课程/图片/2.jpg"></div>"
+"<div id=AdLayer2 style=＇position: absolute;visibility:hidden;z-index:1＇><img src="d:/课程/图片/3.jpg"></div>");
initEcAd()
//-->
</SCRIPT>
