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