此视图包含一个脚本，当单击添加按钮时，将从该脚本调用 UserController Create 方法

控制

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using SmartTrack.Web.Attributes;
using SmartTrack.Web.Models;
using SmartTrack.Web.DAL;
using Telerik.Web.Mvc;
namespace SmartTrack.Web.Controllers
{
    public class UserController : Controller
    {
        SMARTTrackerEntities db = new SMARTTrackerEntities();

        //
        // GET: /User/
        [GridAction]
        public ActionResult Index()
        {
            //ViewData["UserGroup"] = DisplayContentEngine.getUserGroupList();

            return View(new GridModel(UserListEngine.getAllSystemUser()));
        }

        [HttpPost] 
        public ActionResult Create()
        {

            ViewData["Location"] = DisplayContentEngine.getLocationList();
            ViewData["Branch"] = DisplayContentEngine.getBranchList();
            //var v = ViewData.Model = UserListEngine.getAllSystemUser();
            var user = new SysUserList();

            return View(user);
        }

        [HttpPost]
        public ActionResult Create(SysUserList user)
        {
            try
            {
                // TODO: Add insert logic here
                if (ModelState.IsValid)
                {

                    //Save Registration
                    db.SysUserLists.AddObject(user);
                    db.SaveChanges();

                    return RedirectToAction("Index");
                }
                return View(user);
            }
            catch
            {
                return View();
            }

        }

        public ActionResult Edit(string username)
        {
            SysUserList sysuserlist = db.SysUserLists.Single(s => s.UserName == username);
            return View(sysuserlist);

        }
    }
}

这个控制器被称为

创建视图

@{
    ViewBag.Title = "Create";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

@using (Html.BeginForm())

                <td>
                    @(Html.Telerik().DropDownList()
                    .Name("ddLocation")
                    .BindTo((IEnumerable<DropDownItem>)ViewData["Location"])
                    .CascadeTo("ddlBranch")
                    )
                </td>
                <td>
                     <label>Branch</label>

                </td>
            </tr>

        </table>


        </fieldset>
    </div>
}

当单击添加按钮时，什么都没有发生，有人可以告诉我我的问题是什么吗？

您的 ajax 请求中没有数据元素，因此您没有发布任何内容。

如果你想从表单中获取数据，你可以使用 .serialize()：

$.ajax({
    type: "POST",
    data: $('form').serialize(),
    url: '@Url.Action("Create","User")',
    success: function (result) {
        $('#cuscreate').html(result)
    }
});

请记住，这仅在页面上唯一的情况下才有效，否则您应该使用另一个选择器，但您明白了。

来自 HatSoft 的回答更新（赞成！）：

通常在你的标签内你应该有标签，在 MVC 中做到这一点：

<fieldset>
    @using(Html.BeginForm())
    {
        <p>your form</p>
    }
</fieldset>

确保通过从单击处理程序返回 false 来取消提交按钮的默认操作，以便让您的 AJAX 调用有机会执行：

<script type="text/javascript">
    $(function () {
        $('#btnAdd').click(function () {
            $.ajax({
                type: "POST",
                url: '@Url.Action("Create", "User")',
                success: function (result) {
                    $('#cuscreate').html(result)
                }
            });
        });

        return false; // <!-- That's the important bit
    });
</script>

我在您的 html 中看不到表单标签，这可能是它不知道在哪里发布的原因

带有操作链接 Create New 的视图和 telerik 网格中没有表单标签

在纠正我的问题时，我必须修改我的索引视图以包含 div id = cuscreate 这导致 CreateUser 视图显示

@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

<p>
    @Html.ActionLink("Create New", "Create")
</p>

<div id="cuscreate" align="center">
 <fieldset>

      @using (Html.BeginForm())
      {
        //@{

        @(Html.Telerik().Grid<SmartTrack.Web.DAL.SysUserList>()
        .DataBinding(dataBinding => dataBinding.Ajax().Select("Index", "User"))
        .Name("UserList")
        .DataKeys(keys => keys
            .Add(c => c.UserName)
            .RouteKey("UserName"))
        .Columns(columns =>
        {
            columns.Bound(o => o.UserName).Width(100);
            columns.Bound(o => o.FirstName).Width(200);
            columns.Bound(o => o.LastName).Width(250);
            columns.Bound(o => o.Active).ClientTemplate("<input type='checkbox' disabled='disabled' name='Active' <#=Active? checked='checked' : '' #> />").Width(70).HtmlAttributes(new { style = "text-align:center" }); ;


        })
        .Pageable(pagerAction => pagerAction.PageSize(20))
        .Sortable()
        .Selectable()
        .Scrollable()
        .Groupable()

        .HtmlAttributes(new { style = "width:50%;" })

       </div>
  </div>     



    <script type="text/javascript">
        $(function () {
