我必须在哪里获得ajax助手或如何创建它以使用 @ajaxextensions.actionlink

Question

我想在cshtml文件（ASP.NET 6 MVC）中使用 @ajaxextens.actionlink（ajaxhelper，ajaxhelper，string，字符串，字符串，字符串，routevalueDictionary，ajaxoptions）。

@model List<Shift>
@using System.Web.Mvc.Ajax;

@{
    AjaxOptions deleteOptions = new AjaxOptions()
            {
                InsertionMode = InsertionMode.Replace,
                UpdateTargetId = "table"
            };
}

        @foreach (Shift shift in Model)
        {<td>
@AjaxExtensions.ActionLink( ???,"Delete", "DeleteShift", "MainDoctor", new{id=shift.Id}, deleteOptions)
</td>
}

AS 此文档说，ajaxextensions.actionlink仅适用于ASP.NET MVC 5.2，正确的用法应为：

@Ajax.ActionLink("Delete", "DeleteShift", "MainDoctor", new { id = shift.Id }, deleteOptions)

在ASP.NET 6中，您需要使用类似的替代方式下图：

<a data-ajax="true" data-ajax-mode="replace" data-ajax-update="#table" data-ajax-url="@Url.Action("DeleteShift", "MainDoctor", new { id = shift.Id})">Delete</a>

您可以关注一个简​​单的工作演示：

模型：

public class Test
{
    public string Id{ get; set; }
}

view（view/home/index.cshtml）：

@model Test
<div id="table">
    @Model.Id
    <a data-ajax="true" data-ajax-mode="replace" data-ajax-update="#table" data-ajax-url="@Url.Action("DeleteShift", "MainDoctor", new { id = 1 })">Delete</a>
</div>

@section Scripts
{
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-ajax-unobtrusive/3.2.6/jquery.unobtrusive-ajax.js" integrity="sha256-v2nySZafnswY87um3ymbg7p9f766IQspC5oqaqZVX2c=" crossorigin="anonymous"></script>
 
}

控制器：

public class MainDoctorController:Controller
{
    public IActionResult DeleteShift(int id)
    {
        var model = new Test()
        {
            Id = "bb"
        };
        return PartialView("/Views/Home/Index.cshtml", model);
    }
}

public class HomeController : Controller
{
    public async Task<IActionResult> Index()
    {
        var model = new Test()
        {
            Id = "aaa"
        };
        return View(model);
    }
}

结果：
