我的部分观点做错了什么？单击学生行时，我从网页收到“未定义”错误。我尝试了“result”和“result.responseText”，但它仍然提醒“undefined”不知道为什么控制器操作返回错误而不是成功

这是我的标题：

Javascript：

$(function () {
$("tr[name='StudentTableRow']").click(showStudent);    
});

function showStudent() {    
var link = '/Base/ShowSpecificStudent';
var id = this.cells[0].innerText;

$.ajax({
    type: 'POST',
    url: link,
    data: { id: id },
    dataType: 'json',
    success: function (result) {
        $("#StudentDetail").html(result.responseText);
        //$("#StudentDetail").html(result);
    },
    error: function (result) {
        alert(result.message);
    }
});

主视图：

  </div>    
        <% } %> 

</body>
</html>

局部视图：

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<dynamic>" %>

<div>
<table>
        <tr>
            <th>
                Student Description
            </th>               
        </tr>
</table>
<table>
        <% if (Model != null) %>                   
         <%  foreach (var item in Model) { %>
         <tr>
            <td >
                <%: item.StudentDescription%>
            </td>      
        </tr> 
    <%}%>
</table>
</div>

控制器动作：

        [HttpPost()]
        public ActionResult ShowSpecificStudent(string id)
        {
            StudentEntities context = new StudentEntities();
            Int16 studentId = Convert.ToInt16(student);

            ViewData.Model = context.Students.Where(i => i.StudentID == studentId );
            return PartialView("~/Views/Shared/ShowSpecificStudent.ascx", ViewData.Model);
        }

我找到了，我在 JS 函数中的数据类型是 'json' 应该是 'html'
