Javascript操作Cookie的脚本 — CookieHelper

这是一个Javascript操作Cookie的功能封装，对于制作购物车之类的，还是比较实用的，功能包括 添加COOKIE，删除COOKIE，获取COOKIE的值

var HttpCookie = function (name, value, expires, path, domain) {

if (name) this.Name = name;

if (value) this.Value = value;

if (expires) this.Expires = expires;

if (path) this.Path = path;

if (domain) this.Domain = domain;

};

HttpCookie.prototype =

{

Name: '', Value: '', Expires: '', Path: '/', Domain: '',

toCookie: function () {

var NewCookie = this.Name + '=' + this.Value;

if (this.Expires) NewCookie += (';expires=' + this.Expires);

if (this.Path) NewCookie += (';path=' + this.Path);

if (this.Domain) NewCookie += (';domain=' + this.Domain);

return NewCookie;

}

}

var CookieHelper = function () { };

CookieHelper.ConvertToUTCString = function (hourNumber) {

if (!hourNumber || hourNumber == 0) return null;

var Timestamp = (new Date().getTime() + (hourNumber * 1000 * 60 * 60));

return new Date(Timestamp).toUTCString();

};

CookieHelper.Set = function (cookieName, cookieValue, expireHour, path, domain) {

var HC =

new HttpCookie

(

cookieName,

escape(cookieValue),

CookieHelper.ConvertToUTCString(expireHour),

path,

domain

);

document.cookie = HC.toCookie();

};

CookieHelper.Get = function (cookieName) {

var regex = new RegExp(("(^| )" + cookieName + "=([^;]*)(;|$)"));

var Matchs = document.cookie.match(regex);

if (Matchs) return unescape(Matchs[2]);

return null;

};

CookieHelper.Delete = function (cookieName, path, domain) {

if (!CookieHelper.Get(cookieName)) return;

var HC =

new HttpCookie

(

cookieName,

null,

CookieHelper.ConvertToUTCString(-100)

);

document.cookie = HC.toCookie();

};

使用的方法非常简洁：

添加COOKIE，设置COOKIE的值：

CookieHelper.Set(cookieName, cookieValue, expireHour, path, domain);

示例：

CookieHelper.Set('cookie_name', 'cookie_value', 1);

//删除COOKIE

CookieHelper.Delete('cookie_name');

//获取COOKIE的值

CookieHelper.Get('cookie_name');
