![]()
1 using MvcValidateDemo.Models;
2 using System;
3 using System.Collections.Generic;
4 using System.Linq;
5 using System.Web;
6 using System.Web.Mvc;
7
8 namespace MvcValidateDemo.Controllers
9 {
10 public class UserInfoController : Controller
11 {

23
24
25 return View();
26 }
27 [HttpPost]
28 public ActionResult Add(UserInfo userInfo)
29 {
30 //ModelState.IsValid==true那么校验就是成功的
31 if (ModelState.IsValid)
32 {
33
34 }
35 return RedirectToAction("Index");
36 }
37 }
38 }
UserInfo
创建强类型前台页面
![]()
1 @model MvcValidateDemo.Models.UserInfo
2
3 @{
4 Layout = null;
5 }
6
7 <!DOCTYPE html>
8
9 <html>
10 <head>
11 <meta name="viewport" content="width=device-width" />
12 <title>Add</title>
13 </head>
14 <body>
15 <script src="~/Scripts/jquery-1.8.2.min.js"></script>
16 <script src="~/Scripts/jquery.validate.min.js"></script>
17 <script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>
18
19 @using (Html.BeginForm("Index","UserInfo",FormMethod.Get)) {
20 @Html.AntiForgeryToken()
21 @Html.ValidationSummary(true)
22
23 <fieldset>
24 <legend>UserInfo</legend>
25
26 <div class="editor-label">
27 @Html.LabelFor(model => model.UserName)
28 </div>
29 <div class="editor-field">
30 @Html.TextBoxFor(model => model.UserName)
31 @Html.ValidationMessageFor(model => model.UserName)
32 </div>
33
34 <div class="editor-label">
35 @Html.LabelFor(model => model.Age)
36 </div>
37 <div class="editor-field">
38 @Html.TextBoxFor(model => model.Age)
39 @Html.ValidationMessageFor(model => model.Age)
40 </div>
41
42 <p>
43 <input type="submit" value="注册" />
44 </p>
45 </fieldset>
46 }
47
48 <div>
49 @Html.ActionLink("Back to List", "Index")

注意事项：
1：在设置全局校验的时候，引用jquery文件
<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:客户端全局校验设置：在webconfig中
<add key="ClientValidationEnabled" value="true" />
如果为false，则整个全局客户端校验则没有了
如果设置当前某个页面的客户端校验，则使用代码：
![]()
1 @model MvcValidateDemo.Models.UserInfo
2
3 @{
4 Layout = null;
5 }
6
7 <!DOCTYPE html>
8
9 <html>
10 <head>
11 <meta name="viewport" content="width=device-width" />
12 <title>Add</title>
13 <script src="~/Scripts/jquery-1.8.2.min.js"></script>
14 <script src="~/Scripts/jquery.validate.min.js"></script>
15 <script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>
16 </head>
17 <body>
18
19 @{Html.EnableClientValidation(false);}
20
21 @using (Html.BeginForm("Index", "UserInfo", FormMethod.Get))
22 {
23 @Html.AntiForgeryToken()
24 @Html.ValidationSummary(true)
25
26 <fieldset>
27 <legend>UserInfo</legend>
28
29 <div class="editor-label">
30 @Html.LabelFor(model => model.UserName)
31 </div>
32 <div class="editor-field">
33 @Html.TextBoxFor(model => model.UserName)
34 @Html.ValidationMessageFor(model => model.UserName)
35 </div>
36
37 <div class="editor-label">
38 @Html.LabelFor(model => model.Age)
39 </div>
40 <div class="editor-field">
41 @Html.TextBoxFor(model => model.Age)
42 @Html.ValidationMessageFor(model => model.Age)
43 </div>
44
45 <p>
46 <input type="submit" value="注册" />
47 </p>
48 </fieldset>
49 }
50
51 <div>
52 @Html.ActionLink("Back to List", "Index")
53 </div>

@{Html.EnableClientValidation(false);}
