Question

//Index Page (view) /Employee/Index
@model DataAnotaionExample.Models.Employee
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

<form action="./Add">
Enter Name=@Html.TextBoxFor(m=>Model.Name)
@Html.ValidationMessageFor(m=>Model.Name)
    <input type="submit" value="Submit" />
</form>

//雇员主管

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

namespace DataAnotaionExample.Controllers
{
    public class EmployeeController : Controller
    {
        // GET: Employee
        public ActionResult Index()
        {
            return View();
        }enter code here
    }
}

Model类Employee.cs

namespace DataAnotaionExample.Models
{
    public class Employee
    {
        [Required]
        [Key]
        public int Id { get; set; }
        [Required]
        public string Name { get; set; }
    }
}

这是我的代码，如果我将“名称”字段保留为空白，则不会像需要该字段那样抛出错误。

此代码在Asp.Net MVC5框架中创建

Answer 1

确保您已添加

<script src="/Scripts/jquery.validate.js"></script>
<script src="/Scripts/jquery.validate.unobtrusive.js"></script

在布局页面的末尾：

Answer 2

首先，您需要添加剃须刀

@model DataAnotaionExample.Models.Employee
@{
  ViewBag.Title = "Index";
 }

<h2>Index</h2>

<form action="./Add">   
       //this one 
      @Html.ValidationSummary(true)


Enter Name=@Html.TextBoxFor(m=>Model.Name)
@Html.ValidationMessageFor(m=>Model.Name)
 <input type="submit" value="Submit" />
</form>

然后，您应该在“ _Layout.cshtml”页面上喜欢这样的验证脚本

<script src="~/Scripts/jquery.validate.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.js"></script>

或者您可以在App_Start-> BundleConfig中使用此脚本

      bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
       "~/Scripts/jquery-{version}.js",
       "~Scripts/jquery.validate.js",
        "~/Scripts/jquery.validate.unobtrusive.js"

））;

我希望这段代码对您有用。

@ Html.ValidationMessageFor不起作用
