popup.js 包含的JS文件

timePopup=5;
var ns=(document.layers);
var ie=(document.all);
var w3=(document.getElementById && !ie);
adCount=0;
function initPopup(){
if(!ns && !ie && !w3){
return;
}
if(ie){
adDiv=eval('document.all.windlocation.style');
}else if(ns){
adDiv=eval('document.layers["windlocation"]');
}else if(w3){
adDiv=eval('document.getElementById("windlocation").style');
}
if (ie||w3){
adDiv.visibility="visible";
}else{
adDiv.visibility ="show";
}
showPopup();
}
function showPopup(){
if(adCount<timePopup*10){
adCount+=1;
if (ie){
documentWidth =document.body.offsetWidth/2+document.body.scrollLeft-20;
documentHeight =document.body.offsetHeight/2+document.body.scrollTop-20;
} else if (ns){
documentWidth=window.innerWidth/2+window.pageXOffset-20;
documentHeight=window.innerHeight/2+window.pageYOffset-20;
} else if (w3){
documentWidth=self.innerWidth/2+window.pageXOffset-20;
documentHeight=self.innerHeight/2+window.pageYOffset-20;
}
adDiv.left=documentWidth-250;
adDiv.top =documentHeight-150;
setTimeout("showPopup()",100);
}else{
closePopup();
}
}
function closePopup(){
if (ie||w3){
adDiv.display="none";
}else{
adDiv.visibility ="hide";
}
}
onload=initPopup;

把弹出代码放在想执行的文件中就可以了.
