<script language="javascript" type="text/javascript">
       function getCookies()
       {
           var cookies = document.cookie.split(";");
          for(var i=0; i<cookies.length; i++)
         {
               var cookInfo = cookies[i].split("=");
               if(cookInfo[0] == "userInfo") 
               {
                    var userInfo = cookInfo[1].split("#");
                   if(document.getElementById("txtName").value == userInfo[0])
                   {
                      document.getElementById("txtPwd").value = userInfo[1];
                     alert(userInfo[1]);
                   } 
               } 
         }
       } 
  
   </script> 
 <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="txtName" runat="server"></asp:TextBox>
        <br />
        <asp:TextBox ID="txtPwd" runat="server" TextMode="Password"></asp:TextBox>
        <br />
        <asp:CheckBox ID="chkCookie" runat="server" Text="记住密码" />
        <asp:Button ID="btnLogin" runat="server" OnClick="btnLogin_Click" Text="Login" /></div>
    </form>
后台：按钮事件if (chkCookie.Checked)
{
    HttpCookie cookies = new HttpCookie("userInfo");
    cookies.Value = txtName.Text + "#" + txtPwd.Text;
    cookies.Expires = DateTime.Now.AddDays(14);
    Response.Cookies.Add(cookies);
    Response.Cookies.Add(new HttpCookie("Test"));
    Response.Redirect("newPage.aspx");
}

Answer 3

                    //-------------将用户和密码保存到cookie里
                    HttpCookie bcookie = new HttpCookie("UserInfo");
                    bcookie.Values.Add("User_Name",DBClass.EncryptCookie( tbUserName.Value.Replace(" ", "")));
                    bcookie.Values.Add("User_Pwd", MD5(TextBox_Pwd.Text));
                    bcookie.Values.Add("User_Power", DBClass.EncryptCookie("0"));
                    //--------------读取要保存的时间
                    bcookie.Expires = DateTime.Now.AddDays(1);
                    Response.Cookies.Add(bcookie);                 HttpCookie cookies = Request.Cookies["UserInfo"];
                Label1.Text = DBClass.DecryptCookie(cookies.Values["User_Name"]);

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            HttpCookie aCookie = Request.Cookies["userInfo"];
            if (aCookie != null)
            {
                Employee el = new Employee();
                el.UserID = aCookie.Values["userName"];
                if (el.IsOnline())//判断用户是否在线，若在线则删除若不在则直接登陆
                {
                    el.DelOnLine(aCookie.Values["userName"]);
                }
                User_login(aCookie.Values["userName"], aCookie.Values["password"]);
            }
            else if (!string.IsNullOrEmpty(Request.QueryString["Name"]) && !string.IsNullOrEmpty(Request.QueryString["Pass"]))
            {
                User_login(Request.QueryString["Name"], Request.QueryString["Pass"]);
            }        }    }
protected void ibtnLogOn_Click(object sender, EventArgs e)
    {
        if (Ch_Cookie.Checked)
        {
            HttpCookie cok = Request.Cookies["userInfo"];
            if (cok != null)
            {
                //修改Cookie的两种方法
                cok.Values.Set("userName", txtUserId.Value);
                cok.Values.Set("password", txtPassword.Text);
                cok.Values.Set("lastVisit", DateTime.Now.ToString());
                cok.Expires = DateTime.Now.AddDays(30);
                //往Cookie里加入新的内容
                Response.AppendCookie(cok);
            }
            else
