记录学习MVC过程，MVC验证（四）

新建一个用户实体类
public class Users
    {
        public int Id { get; set; }

        [StringLength(5,ErrorMessage = "*长度必须<5")]
        [Required(ErrorMessage = "*姓名必填")]
        public string UserName { get; set; }

        [RegularExpression(@"^\d+$")]
        [Range(18,100)]
        [Required(ErrorMessage = "*")]
        public int Age{get; set; }
    }

   public ActionResult Index()
        {
            return View();
        }
        public ActionResult Add()
        {
            return View();
        }
        [HttpPost]
        public ActionResult Add(User user)
        {
            if (ModelState.IsValid)
            {
                //ModelState.IsValid为true校验成功
            }
            return RedirectToAction("Index");
        }

<script src="~/Scripts/jquery-1.8.2.min.js"></script>
    <script src="~/Scripts/jquery.validate.min.js"></script>
    <script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>

<appSettings>
    <add key="webpages:Enabled" value="false" />
    <add key="EnableClientValidation" value="true" />//全局客户端校验开启
    <add key="EnableUnobtrusiveJavaScript" value="true" />//全局服务端校验开启
  </appSettings>

@{
        Html.EnableClientValidation(false);//当前页面客户端验证关闭
        Html.EnableUnobtrusiveJavaScript(false);//当前服务端验证关闭
    }
