1.MVC Self-band check

Create a new User entity class
public class Users    {public        int Id {get; set;}        [Stringlength (5,errormessage = "* Length must be <5")]        [Required (errormessage = "* Name required")]        public string UserName {get; set;}        [RegularExpression (@ "^\d+$")]        [Range (18,100)]        [Required (errormessage = "*")]        public int age{get; set;}    }

New controller users and create mandatory type views with the creation template

   Public ActionResult Index ()        {            return View ();        }        Public ActionResult Add ()        {            return View ();        }        [HttpPost]        Public ActionResult Add (user user)        {            if (modelstate.isvalid)            {                //modelstate.isvalid = True checksum successful            }            Return redirecttoaction ("Index");        }

　　

Front Page view requires these 3 JS support

<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>

2. Global client (server side) check on or off

In the Web. config configuration

<appSettings>    <add key= "webpages:enabled" value= "false"/> <add    key= "enableclientvalidation "Value=" true "/>//global client check on    <add key=" Enableunobtrusivejavascript "value=" true "/>//global service-side checksum open  </appSettings>

On a page.

@{        html.enableclientvalidation (FALSE);//Current page client validation off        Html.enableunobtrusivejavascript (false);// Current server-side validation off    }
