Question

我在CBLL类中有以下Cookie名称和Cookie项目

    public const string COOKIE_NAME_TDR_FILTER = "jS.TDR.Filter";
    public const string COOKIE_DF_KEY = "DFKey";

在页面中，我们尝试将值分配给Cookie，以便可以在被调用的页面.aspx.cs中使用。

   protected string TDRFilterCookieName = CBLL.COOKIE_NAME_TDR_FILTER;
   protected string CookieDFKey = CBLL.COOKIE_DF_KEY;

在.aspx中使用javascript我试图为CookieDFKey分配值。所以它可以在以后使用。

  var cookie = new Cookie("<%= this.TDRFilterCookieName%>");
  cookie.<%= this.CookieDFKey %> = id;
  cookie.store();
  alert(cookie.<%= this.CookieDFKey %>);

尝试了上面的代码，但它抛出错误，如Cookie（）未定义。请帮助我，因为我是JS Script

的新手

请阅读documentation about cookies

// To create a cookie
document.cookie = "${key}=${value}"; // optional expiration date, see doc.

// To add a new cookie
document.cookie = "${key}=${value}"; // As you can see, `document.cookie` is not a normal Object holding a string

W3学校提供了非常好的方法来添加/获取cookie，我将在这里复制/粘贴（所有功劳归于他们）：

function setCookie(cname, cvalue, exdays) {
    var d = new Date();
    d.setTime(d.getTime() + (exdays*24*60*60*1000));
    var expires = "expires="+ d.toUTCString();
    document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}

function getCookie(cname) {
    var name = cname + "=";
    var ca = document.cookie.split(';');
    for(var i = 0; i <ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') {
            c = c.substring(1);
        }
        if (c.indexOf(name) == 0) {
            return c.substring(name.length,c.length);
        }
    }
    return "";
}

我刚刚写的函数deleteCookie(cname)：

function deleteCookie(cname) {
    document.cookie = cname + "=; expires=Thu, 01 Jan 1970 00:00:00 UTC";
}
