隐藏的层

脚本说明:
第一步：把如下代码加入<body>区域中
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function setupDescriptions() {
var x = navigator.appVersion;
y = x.substring(0,4);
if (y>=4) setVariables();
}
var x,y,a,b;
function setVariables(){
if (navigator.appName == "Netscape") {
h=".left=";
v=".top=";
dS="document.";
sD="";
}
else 
{
h=".pixelLeft=";
v=".pixelTop=";
dS="";
sD=".style";
   }
}
var isNav = (navigator.appName.indexOf("Netscape") !=-1);
function popLayer(a){
desc = "<table cellpadding=3 border=1 bgcolor=F7F7F7 width=200><td>";

if (a==1) desc += "中国最大的综合性网站!";
if (a==2) desc += "中国最大的新闻网站!";
if (a==3) desc += "中国最大的搜索引擎网站!";
if (a==4) desc += "江苏最大的综合性网站!";
if (a==5) desc += "中国最大的网上游戏站点!";

desc += "</td></table>";

if(isNav) {
document.object1.document.write(desc);
document.object1.document.close();
document.object1.left=x+25;
document.object1.top=y;
}
else {
object1.innerHTML=desc;
eval(dS+"object1"+sD+h+(x+25));
eval(dS+"object1"+sD+v+y);
   }
}
function hideLayer(a){
if(isNav) {
eval(document.object1.top=a);
}
else object1.innerHTML="";
}
function handlerMM(e){
x = (isNav) ? e.pageX : event.clientX;
y = (isNav) ? e.pageY : event.clientY;
}
if (isNav){
document.captureEvents(Event.MOUSEMOVE);
}
document.onmousemove = handlerMM;
//  End -->
</script>
<div id="object1" style="position:absolute; visibility:show; left:25px; top:-50px; z-index:2">隐藏的层</div>

第二步：把<body>区域改为
<body bgcolor="#fef4d9" OnLoad="setupDescriptions()">
