【问题描述】：

我想在提交表单后弹出一个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();
        }
    }

                     new SelectListItem{Text="Female", Value="F"}}, "Please select")
                </td>
            </tr>
            <tr>

                    @Html.TextBoxFor(m => m.City)
                </td>
            </tr>
            <tr>
                <td></td>

可以使用 JavaScript、Modal 和 Json

标签： asp.net-mvc-4 asp.net-mvc-5

【解决方案1】：

您可以简单地使用 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();
}

在正文末尾添加一个脚本，

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