How to assign values in the cookies Javascript

I have the following Cookie Name and Cookie Item in a CBLL class as 

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

In the Page we try to assign the values to the cookies so it can be used in the called pages, .aspx.cs.

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

In the .aspx using the javascript I am trying to assign the values for the CookieDFKey. So it can be used later.

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

Tried the above code but it throws error like Cookie() is not defined. Please help me with this as I am new to JS Script

Please read 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 Schools provides very good methods to add/get cookies, that I will copy/paste here (All the credit goes to them):

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 "";
}

And a function deleteCookie(cname) that I just wrote:

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