Example Analysis of client Verification of ASP.NET MVC5
This article mainly shows you the "sample analysis of client-side verification of ASP.NET MVC5", which is easy to understand and well-organized. I hope it can help you solve your doubts. Let the editor lead you to study and study the "sample analysis of client-side verification of ASP.NET MVC5".
Client-side verification, using Jquery and Jquery plug-ins to implement [jquery.validate.min.js and jquery.validate.unobtrusive.min.js)]
In server-side verification, the page must be submitted to the server for verification. If the data verification fails, the server will send a response to the client, and then the client will process it according to the corresponding information. Client verification is different. As soon as the data entered by the user is submitted, the client will verify it first. If it does not pass, the client will report an error and will not submit it to the server for verification. If it is passed, the request will be transmitted to the server.
If you are using a version above VS2012, it comes with client-side authentication enabled: [of course, you can also manually add the following configuration. ]
We are still the previous project:
Using System;using System.Collections.Generic;using System.ComponentModel.DataAnnotations;using System.Linq;using System.Web;namespace Server_Side_Validation_IN_MVC.Models {public class StudentServer {[Required (ErrorMessage= "Name is required")] public string Name {get; set;} [Required (ErrorMessage= "email must")] [EmailAddress (ErrorMessage= "email format is incorrect")] public string Email {get; set } public ActionResult SeverSideIndex () {return View ();} [HttpPost] public ActionResult SeverSideIndex (StudentServer model) {if (ModelState.IsValid) {ViewBag.Name = model.Name; ViewBag.Email = model.Email;} return View ();}
The difference is, here, I add views, different:
Note that the reference script library must be checked here, that is, the Jquery and Jquery plug-ins are introduced in order to perform client-side verification:
Modify the default route:
Public static void RegisterRoutes (RouteCollection routes) {routes.IgnoreRoute ("{resource} .axd / {* pathInfo}"); routes.MapRoute (name: "Default", url: "{controller} / {action} / {id}", defaults: new {controller = "Student", action = "SeverSideIndex", id = UrlParameter.Optional});}
Run the project:
We add a breakpoint to the controller's POST method
Click the button directly: the POST method is not called, and the validity of the data is verified directly on the client side.
Enter legal data:
The breakpoint is triggered, that is, after the client verification is passed, it is submitted to the server for further processing.
Well, this is client-side authentication, which is relatively simple. But be careful to introduce the Jquery plug-in
