c# – mvc PartialView with Dialog Partial View显示html

<form action="/Plt/FileUpload" method="post"><input data-val="true" data-val-number="The field PlNum must be a number." data-val-required="The PlNum field is required." id="PlNum" name="PlNum" type="hidden" value="36028" />     <div id="errMsg" >

     </div>
     <p>File upload for Pl# 36028</p>
     <input type="file" name="file" />
     <input type="submit" value="OK" />
     </form>

这是控制器动作：

public ActionResult FileUpload(int id)
       {
         var model = new FileUpload { PlNum = id };
         return PartialView(model);
       }

这是PartialView的视图：

@model Ph.Domain.Lb.Models.FileUpload

    <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>

@using (Html.BeginForm("FileUpload","Plts",FormMethod.Post,null))
    {

      @Html.HiddenFor(a => a.PlNum)

     <div id="errMsg" >
     @if (TempData["ErrMessage"] != null)
     {
       @TempData["ErrMessage"]
     }
     </div>

    <p>File upload for Pl# @Model.PlNum</p>
    <input type="file" name="file" />
    <input type="submit" value="OK" />
   }

这是我的ajax调用的样子：

var url = '@Url.Action("FileUpload","Plt")' + '?id=' +  encodeURIComponent(rowid);

                 $.ajax({
                           url: url,type: 'GET',success: function(result) {                                    

                if (result.success) {
                  $('#dialog').dialog('close');
                } else {

             // refresh the dialog
                $('#dialog').html(result);
             }
         }

回顾一下,ajax调用确实到达ActionResult,但不确定它何时尝试显示部分视图,它显示HTML与渲染的html.
