静态页动态读写Cookie

首页登录代码如下

//存入cookie  
            HttpCookie newCookie = new HttpCookie("User");  
            newCookie.Expires.AddMinutes(30);//设置时间  
            newCookie.Values.Add("uid","001");  
            newCookie.Values.Add("username","leo li");  
            Response.AppendCookie(newCookie);

html 代码如下

<html>  
<title>测试</title>

    function GetCookie(sMainName, sSubName) {  
        var sCookieName = sMainName + "=";
