求助AjaxSubmit提交后的问题
用ajaxSubmit提交的有个问题如何才能获得返回的值？
后台代码如下：

C# code


    protected void Page_Load(object sender, EventArgs e)
    {
        string a = Request.Form["hello"];
        string b = Request.QueryString["id"];
        if (IsPostBack)
        {
            Response.Write("<script>alert('"+a+"');</script>");
        }
    }

a是有值的,页面是用 ajaxSubmit无刷新的提交
