JS merekam kode implementasi nomor login pengguna

复制代码代码如下:

fungsi www_helpor_net (offset) {

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

if (endstr == -1)

endstr = document.cookie.length;

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

}

fungsi 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)

merusak;

}

kembali nol;

}

fungsi setCookie (name, value) {

var argv = setCookie.arguments;

var argc = setCookie.arguments.length;

var kedaluwarsa = (2 <argc)? Argv [2]: null;

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

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

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

document.cookie = name

+ "="

+ Escape (Nilai)

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

.togmtString ()))

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

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

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

}

var expdate = new date ();

vis kunjungan;

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

if (! (visit = getCookie ("visit"))) {

kunjungan = 0;

}

var oldJessionId = getCookie ("OldJSessionId");

if (! oldJessionId) {

OldJessionId = "111";

}

var newJessionId = getCookie ("jSessionId");

if (oldJessionId! = newjessionId) {

kunjungan ++;

SetCookie ("OldjSessionID", newjessionId, expdate, "/", null, false);

SetCookie ("kunjungan", kunjungan, 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>" + kunjungan + "</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 (kunjungan> 3) {

setInterval ("changeH ('down')", 2);
