Question

我想在提交表单后弹出消息框以通知用户成功消息。

我有以下控制器和视图。

 public class HomeController : Controller
    {
        // GET: Home
        public ActionResult Index()
        {
            return View();
        }

        [HttpPost]
        public ActionResult Index(PersonModel person)
        {
            int personId = person.PersonId;
            string name = person.Name;
            string gender = person.Gender;
            string city = person.City;

            return View();
        }
    }

        table {

        table th {

            color: #333;
            font-weight: bold;
        }

        table th, table td {
            padding: 5px;
            border: 1px solid #ccc;
        }

        table, table table td {

        }

            </tr>
            <tr>

您只需为此使用ViewBag和Javascript。

在您的控制器中：

public ActionResult Index()
{
    ViewBag.SuccessMessage = "";
    return View();
}

[HttpPost]
public ActionResult Index(PersonModel person)
{
    int personId = person.PersonId;
    string name = person.Name;
    string gender = person.Gender;
    string city = person.City;

    ViewBag.SuccessMessage = "Data has been Inserted!"

    return View();
}

在身体末端添加脚本，

<script>
    $(document).ready(function() {
        if(@ViewBag.SuccessMessage != ""){
            alert(@ViewBag.SuccessMessage);
        }
    });
</script>
