Question

我正在尝试从模式弹出窗口中删除我的删除按钮以从Visual Studio中的本地数据库中删除一行。

我不太清楚如何做到这一点。我是新手，所以如果我必须添加一些数据。请通知我。

这是控制器：

using MusicBox.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Mvc;

namespace MusicBox.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }

        public ActionResult About()
        {
            ViewBag.Message = "Your application description page.";

            return View();
        }

        public ActionResult Contact()
        {
            ViewBag.Message = "Your contact page.";

            return View();
        }

        //Tab Box
        //[HttpGet]
        public ActionResult Box()
        {
            return View();
        }

Answer 1

会是这样的： -

的Javascript

<script>
  $(document).ready(function () {
  $('#confirmSongDelete').on('show.bs.modal', function (e) {
    var id = $(e.relatedTarget).attr('id');
    $("#btnConfirm").attr("id", id);
  });
 })

function DeleteSong(Id) {

$("div[class='Success']").empty();
$("div[class='failure']").empty();
//call action method
$("#confirmSongDelete").modal("hide");

$.ajax({
    url: "@Url.Action("DeleteSong", "HomeController")",
    data: { id: Id },
    success: function (response) {
        if (response != null && response == "True") {
            $("#spnSuccessMsg").css("display", "block");
            $("#myModalOk").modal('show');

        } else {
            $("#spnErrorMsg").css("display", "block");
            $("#myModalOk").modal('show');

        }
      window.location.href = window.location.href;
    }
});
}
 </script>
