ASP.NET MVC 3 AJAX请求返回404 Not Found错误

Question

这里是我的代码（以下发现的问题）：

VIEW

// This function is called by another function when radioButtonGroup.change(). 
var requestValues = function (form) { 
    var option = form.find("input:radio:checked").attr("value"); 

    // This seemingly shows the correct url for the action method desired. 
    alert("Form Action: " + form[0].action + "\nForm Method: " + form[0].method); 

    if (form.valid()) { 
     $.ajax({ 
      url: form[0].action, 
      type: form[0].method, 
      data: option, 
      success: function (result) { 
       alert("Had success."); 
       $('#createForm').replaceWith(result); 
      }, 
      error: function (xhr) { 
       alert("An error occurred: " + xhr.status + " " + xhr.statusText); 
      } 
     }); 
    } 
    return false; 
} 

...(other code here)... 

@using (Html.BeginForm("CreateForm", "MyController", FormMethod.Post, 
         new { @id = "optionForm" })) 
{ 
    <div id="options"> 
     @foreach (MyOption op in Model.GetOptions()) { 
      <div class="editor-field"> 
      @Html.RadioButton("formOption", op.OptionType, false, 
       new { @id = op.ID, @title = @op.Description }) 
      <label for="@op.ID">@op.Name</label> 
      </div> 
     } 
    </div> 
    <input type="submit" value="Select" style="display:none;" /> 
} 

控制器

[HttpPost] 
public PartialViewResult CreateForm(MyOptionType formOption) { 
    MyViewModel model = new MyViewModel(); 
    model.ApplyOptionValues(formOption); 
    return PartialView("_CreateForm", model); 
} 

REGISTER ROUTES

// Default 
routes.MapRoute(
    "Default", // Route name 
    "{controller}/{action}/{id}", // URL with parameters 
    new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults 
); 

我的问题是，当我点击一个单选按钮，执行AJAX请求，但我得到了“404 Not Found”错误（尽管jQuery函数中的alert似乎显示了适当的url）。我昨天花了整整一天的时间，我无法弄清楚什么是错误的。我在IIS Express上运行ASP.NET MVC 3应用程序，并且我没有使用区域（我知道的）。任何人有任何建议如何解决这个问题？谢谢。

EDIT

警报框显示以下消息：

Form Action: https://localhost:44300/MyController/CreateForm

Form Method: post

EDIT

这里是，再现误差的整个测试图和测试控制器：

VIEW

<h2>TestAction</h2> 

<script type="text/javascript"> 
    $(document).ready(function() { 
     $("#optionForm input[name='radioOption']").change(function() { 
      requestValues($(this).closest("form")); 
     }); 

     var requestValues = function (form) { 
      var option = form.find("input:radio:checked").attr("value"); 

      alert("Form Action: " + form[0].action + "\nForm Method: " + form[0].method); 

      if (form.valid()) { 
       $.ajax({ 
        url: form[0].action, 
        type: form[0].method, 
        data: option, 
        success: function (result) { 
         alert("AJAX success."); 
         //$('#createForm').replaceWith(result); 
        }, 
        error: function (xhr) { 
         alert("An error occurred: " + xhr.status + " " + xhr.statusText); 
        } 
       }); 
      } 
      return false; 
     } 
    }); 
</script> 

@using (Html.BeginForm("CreateForm", "Test", FormMethod.Post, new { @id = "optionForm" })) { 
    @Html.RadioButton("radioOption", "value1", false, new { @id = "radioButton1" }) 
    <label for="radioButton1">Radio Button 1</label> 
    @Html.RadioButton("radioOption", "value2", false, new { @id = "radioButton2" }) 
    <label for="radioButton2">Radio Button 2</label> 
    @Html.RadioButton("radioOption", "value3", false, new { @id = "radioButton3" }) 
    <label for="radioButton3">Radio Button 3</label> 

    <input type="submit" value="Select" style="display:none;" /> 
} 

<div id="createForm"></div> 

控制器

public class TestController : Controller { 
    public ActionResult TestAction() { 
     return View(); 
    } 

    [HttpPost] 
    public ActionResult CreateForm(string option) { 
     return View("TestAction"); 
    } 
} 

Answer 1

@using (Html.BeginForm("CreateForm", "MyController", FormMethod.Post, new { id = "optionForm" })) 

应该是：

@using (Html.BeginForm("CreateForm", "My", FormMethod.Post, new { id = "optionForm" })) 

请记住，在ASP.NET MVC佣工，你不应该通过Controller后缀。假定。

所以正确的URL应该是：

https://localhost:44300/My/CreateForm 

，而不是：

https://localhost:44300/MyController/CreateForm 

，你明明有MyController类：

public class MyController: Controller 
{ 
    public ActionResult CreateForm(MyOptionType formOption) 
    { 
     ... 
    } 
}
