Question

以下是控制器：

  [HttpPost]
        public ActionResult Save(HelloWorldMvcApp.ProductData model, string[] imgToDelete)
        {
            return Json(new { success = true });
        }

以下是视图：

  @model HelloWorldMvcApp.ProductData model

    @{
        ViewBag.Title = "Edit";
        Layout = "~/Views/Shared/_SharedLayout.cshtml";
    }

    <h2>Edit</h2>

    @using (Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "divProductData", OnSuccess = "hideModal", Url = Html.Action("Save").ToHtmlString() }))
    {
        <div id="divProductData">
         <table>
         <tr>
            <td>
              @Html.HiddenFor(a => a.id)
            </td>
            <td>
              @Html.TextBoxFor(a => a.productDesc)
            </td>
         </tr>
         <tr>
            @foreach (string path in Model.picture.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries))
                    {
                        <td>
                            <input type="checkbox" name="imgToDelete" value="@path">
                            <br />
                            <img src='~/Images/Product/@path' />
                        </td>
                    }
          </tr>


            </table>

        </div>
       }

  @section scripts{
      <script>
        function hideModal() {
            $('.modal').modal('hide');
            $('body').removeClass('modal-open');
            $('.modal-backdrop').remove();
        }
    </script>
  }

@using (Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "divProductData", OnSuccess = "hideModal", Url = Html.Action("Save").ToHtmlString() }))引发了一个例外：

{＆＃34;一种公共行动方式＆＃39;保存＆＃39;在控制器上找不到＆＃39; HelloWorldMvcApp.ProductDataController＆＃39;＆＃34;}

这里是代码的小提琴： https://dotnetfiddle.net/OLEq4o

如何解决此错误？

我尝试使用Ajax.BeginForm而不是Html.BeginForm，因为此页面显示在Bootstrap模式中，经过一些研究后，我无法调用＆＃34; hideModal＆＃34;函数，如果我使用Html.BeginForm

Close modal window containing ASP MVC Ajax form

如果我错了，请纠正我

Answer 1

哦......我想通了，首先，我将动作名称移到了AjaxOptions之外，然后我将[HttpPost]属性更改为控制器中的[AcceptVerbs(HttpVerbs.Get)]，并添加了JsonRequestBehavior.AllowGet in JSON结果，结果如下：

Answer 2

尝试指定控制器名称。

@using (Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "divProductData", OnSuccess = "hideModal", Url = Html.Action("Save","controllerName").ToHtmlString() }))

MVC在控制器上找不到公共操作方法
