asp.net js 存取cookie

asp.net

//根据地址设置cookie

            string CityName = "";

                if (companyID == )

                {

                    CityCookieKey.Value = "FZ";

                    CityCookieValue.Value = "";

如果是*域名下的二级域名跨域可以设置cookie的domain

//写cookies

function setCookie(name, value,time) {

    var Days = time||365;

    var exp = new Date();

        exp.setTime(exp.getTime() + Days * 24 * 60 * 60 * 1000);

        document.cookie=name+"="+escape(value)+";expires="+exp.toGMTString()+";path=/;";

}

//读取cookies

function getCookie(sName) {

    var aCookie = document.cookie.split("; ");

    for (var i = 0; i < aCookie.length; i++) {

        var aCrumb = aCookie[i].split("=");

        if (sName == aCrumb[0])

            return unescape(aCrumb[1]);

    }

    return null;

}

//删除cookies

function delCookie(name) {

    var exp = new Date();

    exp.setTime(exp.getTime() + -1 * 24 * 60 * 60 * 1000);

    var cval = getCookie(name);

    if (cval != null)

        document.cookie = name + "=;expires=" + exp.toGMTString() + "; path=/;";

}

//清楚所有cookie

function clareCookie() {

    var strCookie = document.cookie;

    var arrCookie = strCookie.split("; "); // 将多cookie切割为多个名/值对

    for (var i = 0; i < arrCookie.length; i++) { // 遍历cookie数组，处理每个cookie对

        var arr = arrCookie[i].split("=");

        if (arr.length > 0)

            delCookie(arr[0]);

    }

}

            //那么当用户在指定时间内访问我们的网站，那么属于我们网站的Cookie数据会放在请求报文中发送过来，

            //其它网站的Cookie不会发送。

           // Response.Cookies["cp3"].Domain = "xxx.com";//设置主域的。

            Response.Cookies["cp3"].Path = "/2015-5-31";

            Response.Cookies["cp3"].Expires = DateTime.Now.AddDays();

            //另外一种创建Cookie的方式。

            HttpCookie cookie1 = new HttpCookie("cp4","sssss");

            cookie1.Expires = DateTime.Now.AddDays();

            Response.Cookies.Add(cookie1);

        }
