以下是我截取的一段代码，但我不会分析，请高手来分析一下，这种强制弹出的原理是什么，而且不被任何工具拦截，并且每天只弹一次，现在很多广告联盟都用这个弹出方式，淘宝啊什么的都是！！
大家研究一下！
<script language="javascript">
document.write("");
function GetCookie_265 (name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen){
var j = i + alen;
if (document.cookie.substring(i, j) == arg) return getCookieVal_265 (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function SetCookie_265 (name, value){
var argv = SetCookie_265.arguments;

var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
