复制代码 代码如下:

function www_helpor_net(offset) {

var endstr = document.cookie.indexOf(";", offset);

if (endstr == -1)

endstr = document.cookie.length;

return unescape(document.cookie.substring(offset, endstr));

}

function GetCookie(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 www_helpor_net(j);

i = document.cookie.indexOf(" ", i) + 1;

if (i == 0)

break;

}

return null;

}

function SetCookie(name, value) {

var argv = SetCookie.arguments;

var argc = SetCookie.arguments.length;

var expires = (2 < argc) ? argv[2] : null;

var path = (3 < argc) ? argv[3] : null;

var domain = (4 < argc) ? argv[4] : null;

var secure = (5 < argc) ? argv[5] : false;

document.cookie = name

+ "="

+ escape(value)

+ ((expires == null) ? "" : ("; expires=" + expires

.toGMTString()))

+ ((path == null) ? "" : ("; path=" + path))

+ ((domain == null) ? "" : ("; domain=" + domain))

+ ((secure == true) ? "; secure" : "");

}

var expdate = new Date();

var visits;

expdate.setTime(expdate.getTime() + (24 * 60 * 60 * 1000 * 365)); //设置COOKIES时间为1年,自己随便设置该时间

if (!(visits = GetCookie("visits"))) {

}

var oldjessionid = GetCookie("OLDJSESSIONID");

if (!oldjessionid) {

}

if (oldjessionid != newjessionid) {

visits++;

SetCookie("OLDJSESSIONID", newjessionid, expdate, "/", null, false);

SetCookie("visits", visits, expdate, "/", null, false);

}

//以下信息显示可以使用标准的HTML语法,自己随便设置

document.write("你已经光临本页" + "<FONT COLOR=red>" + visits + "</FONT>"+ "次！");

//当登录次数达到三次，就自动调用函数，隐藏弹出框，如果只要记录登录次数，下边代码可以忽略

if (visits > 3) {
