confirm 确认框的一个实际应用

现使用form post 的方式来进行改写。

前台页面 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript">
        function CustomSubmit() {
            var form = document.getElementById('<%=form1.ClientID %>');
            document.getElementById('hID').value = confirm('确认执行么？');
            form.submit();
        }
    
     </script>
</head>
<body>
    <form id="form1" runat="server">
        <input type="hidden" id="hID" name="hName" />
        <asp:Button ID="btnCallBack" runat="server" Text="回发并弹出confirm" OnClick="btnCallBack_Click" />
        <br />
        <asp:Literal ID="lit" runat="server"></asp:Literal>               
    </form>
</body>
</html>
后台页面 
private Dictionary<bool, Action> dic;

    protected void Page_Load(object sender, EventArgs e)
    {
        string value = Request.Form["hName"] ?? "";

        bool result;

        if (bool.TryParse(value, out result))
        {
            dic = new Dictionary<bool, Action>();

            dic.Add(true, Confirm);
            dic.Add(false, Cancel);

            dic[result]();
        }
    }
    protected void btnCallBack_Click(object sender, EventArgs e)
    {
        // 先执行一段代码
        lit.Text = DateTime.Now.ToString("yyyy-MM-dd");


        //弹出confirm

        ClientScript.RegisterStartupScript(GetType(), "confirm", "CustomSubmit();", true);
    }

    //确认时执行的代码
    private void Confirm()
    {
        lit.Text = "确认";
    }

    //取消时执行的代码
    private void Cancel()
    {
        lit.Text = "取消";
    }
