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');
