使用mvc的文本框中不显示Json值

Question

JSON 数据不显示在文本中，我创建了一个 json 函数，它返回表数据函数运行良好，函数没有错误。
现在函数执行成功时使用 json 调用函数然后空白屏幕显示不显示任何数据。
当我将var Mname 放入alert(Mname) 时，数据会在我返回表单控制器时显示。

var Mname = @Html.Raw(Newtonsoft.Json.JsonConvert.SerializeObject(TempData["Iname"]));
alert(Mname);
$(function() {

  $.ajax({
    type: "POST",
    url: '@Url.Action("MemberInformation_Detail")',
    data: Mname,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: OnSuccess,
    failure: function(response) {
      alert(response.d);
    },
    error: function(response) {
      alert(response.d);
    }
  });

  function OnSuccess(response) {


    var table = $("#dvCustomers table").eq(0).clone(true);
    var customers = response;

    $("#dvCustomers table").eq(0).remove();
    $(customers).each(function() {
      $(".MemberID", table).val(this.MemberShipID);
      $(".name", table).val(this.name);
      $(".FName", table).val(this.FName);
      $(".Gender", table).val(this.Gender);
      $(".address", table).val(this.address);
      $(".phone1", table).val(this.phone1);
      $(".mobileno", table).val(this.mobileno);
      $(".email", table).val(this.email);
      //$(".ClientPic", table).val(this.ClientPic);

      //alert(this.ClientPic);

      $(".ClientPic", table).attr("src", "data:image/png;base64," + this.ClientPic);



      $("#dvCustomers").append(table).append("<br />");
      table = $("#dvCustomers table").eq(0).clone(true);
    });
  }
});

<form id="form1" action="">
  <div id="dvCustomers">
    <table class="tblCustomer" cellpadding="2" cellspacing="0" border="1">
      <tr>
        <th>

我已经在我的机器上测试了这段代码，它工作正常，我希望它也对你有用。

控制器

[HttpPost]
    // Receive parameters what you are passing
    public ActionResult MemberInformation_Detail(string name, string FName)
    {
        // return proper json object that contains all properties that you are using in js
        return Json(new { MemberShipID = 123, name = "Test", FName = "Fathename", Gender = "Male", address = "N/A", phone1 = "123456789", mobileno = "123456789", email = "abc@abc.com", ClientPic = "clientpic" });
