jQuery $ Ajax将数据从webform发布到ASP.NET中的代码隐藏方法

Question

我试图将数据从webform传递给代码隐藏方法并在webform中获取值,然后打印它.我最初测试以下代码只是简单地发布请求到方法,获取字符串并在页面中打印并且它有效,但在尝试将数据发布回方法时出现问题

$(document).ready(function () {

$(".AddStaffToRoleLink").on("click", function () {

           var selectedStaffID = $(this).attr("id");

           alert("this is " + selectedStaffID);

           $.ajax({

               type: "POST",
               url: "AddUserInRole.aspx/AddRoleForSelectStaff",
               contentType: "application/json; charset=utf-8",
               dataType: "json",
               data: { selectedStaffID: selectedStaffID },
               success: function (response) {
                   $("#Content").text(response.d);
               },
               failure: function (response) {
                   alert(response.d);
               }
           });
       });

});

代码背后

   [WebMethod]
    public static string AddRoleForSelectStaff(string selectedStaffID)
    {
        return "This string is from Code behind  " + selectedStaffID;
    }

这里是将sigle数据发布到方法后面的webform代码的方法...

  $(document).ready(function () {

 $(".AddStaffToRoleLink").on("click", function () {

           var selectedStaffID = $(this).attr("id");

           alert("this is " + selectedStaffID);

           $.ajax({
               url: 'AddUserInRole.aspx/AddRoleForSelectStaff',
               type: "POST",
               data: "{'GivenStaffID':'" + selectedStaffID +"'}",
               contentType: "application/json; charset=utf-8",
               dataType: "json",
               success: function (response) {
                   $("#Content").text(response.d);
               },
               failure: function (response) {
                   alert(response.d);
               }
           }).done(function (response) {
               alert("done "+response );
           });
       });
   });

Code Behind方法

 [WebMethod]
    public static string AddRoleForSelectStaff(string GivenStaffID)
    {
        var staffID = Convert.ToInt32(GivenStaffID);

        return "This string is from Code behind  " + GivenStaffID;
    }
