MVC校验

新建一个Model

 1 using System;
 2 using System.Collections.Generic;
 3 using System.ComponentModel.DataAnnotations;
 4 using System.Linq;
 5 using System.Web;
 6 
 7 namespace MvcValidateDemo.Models
 8 {
 9     public class UserInfo
10     {
11         public int Id { get; set; }
12         [StringLength(5, ErrorMessage = "*长度必须小于5")]
13         [Required(ErrorMessage = "*姓名为必填项")]
14         public string UserName { get; set; }
15         [RegularExpression(@"^d+$")]
16         [Range(18, 20)]
17         public int Age { get; set; }
18     }
19 }

UserInfo

创建UserInfo控制器

 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     {
12         //
13         // GET: /UserInfo/
14 
15         public ActionResult Index()
16         {
17             return View();
18         }
19 
20 
21         public ActionResult Add()
22         {
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")
50     </div>
51 </body>
52 </html>

Add

注意事项：

1：在设置全局校验的时候，引用jquery文件

2:客户端全局校验设置：在webconfig中

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>
54 </body>
55 </html>

@{Html.EnableClientValidation(false);}

其中默认为true，改为false，则当前页面客户端校验失效
