C#中Cookie的存取

-----------------------------------------------------------------------------------------------------------

/// <summary>
/// 创建cookie并赋值，设置cookie有效时间
/// </summary>
/// <param name="strCookieName">cookie名字</param>
/// <param name="strCookieValue">cookie值</param>

      cookie.Value = strCookieValue;
      //设置cookie的有效期 或者cookie.Expires.AddDays(intDay);
      cookie.Expires = DateTime.Now.AddDays(intDay);
      System.Web.HttpContext.Current.Response.Cookies.Add(cookie);
      return true;

jQuery中Cookie的存取

-----------------------------------------------------------------------------------------------------------

//创建一个key为uName，值为cookievalue的cookie，有效期为3天
$.cookie("uName", "cookievalue", { expires: 3});

//读取cookie值
$.cookie("uName");

//删除cookie
$.cookie("uName", null);

注意：要记得引用两个js文件

<script src="jquery-1.11.2.js" type="text/javascript"></script>

<script src="jquery.cookie-v1.4.1.js" type="text/javascript"></script>
