Asp.net MVC使用Ajax从PartialView的actionlink加载父视图不起作用

我有一种情况，需要从ParentView的局部视图调用它。就像我在Partial视图中有ToDos列表一样，Ajax操作链接用于通过传递id来编辑父级中的数据。在不使用Ajax的情况下，它也可以通过放入querystring来操作url。但我们希望与Ajax进行内部通话，Ajax不会开火。

我们使用的代码如下：

<li>@Ajax.ActionLink(@item.ToDoTitle, "Index", new { tdid = @item.ToDoId }, new AjaxOptions { UpdateTargetId = "saved", InsertionMode = InsertionMode.Replace, HttpMethod="POST" })</li>

控制器是这样的：

public ActionResult Index(int tdid =0)
    {
        if (tdid !=0)
        {
            ToDo t = new ToDo();
            t.ToDoTitle = "Ramlal";
            t.ToDoDesc = "Shyamlal";
            t.ToDoId = tdid;
            return Json(t);
        }
        else
        {
            return View();
        }
    }

我们也尝试过返回视图，但没有发生任何事情，所以我们尝试使用Json作为它的返回模型。

如果我错了，请纠正我？

仅供参考，这是父视图：

@model myTask.Models.ToDo
@{
    ViewBag.Title = "My Task";
}
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script>
@using (Ajax.BeginForm("Save", new AjaxOptions() { InsertionMode = InsertionMode.Replace, UpdateTargetId = "MyTaskList" }))
{
    @Html.AntiForgeryToken()
    <div class="MyTask">
        @Html.HiddenFor(t => t.ToDoId)
        <div class="row">
            <div class="col-lg-12">
                @Html.LabelFor(t => t.ToDoTitle)<br />
                @Html.TextBoxFor(t => t.ToDoTitle)
            </div>
            <div class="col-lg-12">
                @Html.LabelFor(t => t.ToDoDesc)<br />
                @Html.TextAreaFor(t => t.ToDoDesc)
            </div>
        </div>
        <script>
            $( "#ToDoTitle" ).blur( function() {
                $.ajax({
                    url: "Save",
                    type: "POST",
                data: $("#form0").serialize(),
                dataType: "json"
                }).done(function (model) {
                $("#ToDoId").val(model.ToDoId);
                $("#ToDoTitle").val(model.ToDoTitle);
                $("#ToDoDesc").val(model.ToDoDesc);
            });
            });
            $("#ToDoDesc").blur(function () {
                if ($("#ToDoId").val() > 0) {
                    $.ajax({
                        url: "Save",
                        type: "POST",
                        data: $("#form0").serialize(),
                        dataType: "json"
                    }).done(function (model) {
                        $("#ToDoId").val(model.ToDoId);
                        $("#ToDoTitle").val(model.ToDoTitle);
                        $("#ToDoDesc").val(model.ToDoDesc);
                    });
                }});
        </script>
    </div>
    <div class="ObjectList" id="MyTaskList">
        @Html.Action("TodoList")
    </div>
    <div class="clearfix"></div>
}

这是使用@Html.Action（"TodoList"）调用的部分视图

@using System.Linq
@model myTask.Models.ToDoList
@{
    ViewBag.Title = "Index";
}
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script>
<div class="row">
    @if (Model.ToDos.Count > 0)
    {
        <ul>
            @foreach (var item in Model.ToDos)
            {
                @*<li>@Html.ActionLink(@item.ToDoTitle, "Index", new { tdid = @item.ToDoId })</li>*@
                <li>@Ajax.ActionLink(@item.ToDoTitle, "/Index", new { tdid = @item.ToDoId }, new AjaxOptions { UpdateTargetId = "MyTask", InsertionMode = InsertionMode.Replace, HttpMethod = "POST" })</li>
            }
        </ul>
    }
</div>

控制器：

using myTask.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Web;
using System.Web.Mvc;

    {
        // GET: Tasktd

        {
            if (tdid !=0)
            {
                ToDo t = new ToDo();
                t.ToDoTitle = "Ramlal";
                t.ToDoDesc = "Shyamlal";
                t.ToDoId = tdid;
                return PartialView(t);
            }
            else
            {
                return View();

            {
                var t = await td.Save(td);
                return Json(td);
            }
            return Json("Oops! Error Occured");
        }
        [ChildActionOnly]
        public PartialViewResult TodoList()
        {
            ToDoList tdl = new ToDoList();
            List <ToDo> tds= new List<ToDo>();
            ToDo t = new ToDo();
            t.ToDoId = 1;
            t.ToDoTitle = "XXX";
            tds.Add(t);
            tdl.ToDos = tds;
            return PartialView(tdl);
        }
    }
}
