一、概述
MVC分为ViewModel、Control、View,对数据的封装MVC做的很好,确实是不错的WEB框架,针对MVC的ViewModel封装的也是相当的不错,最近做一个MVC的项目,采用的框架MVC4+JQuery+JQueryUI。由于开发需要,也特别研究了一下MVC中的ViewMode的数据校验,觉得MVC这种模式真的真赞,现总结一下ViewModel的使用方式;
二、ViewModel基础特性
基本特性的命名空间位于: System.ComponentModel.DataAnnotations 和 System.Web.Mvc;
1、Required
说明:必填项,当提交数据该缺少的时候,就会引发异常;
举例:[Required]
2、StringLength
说明:指定运行的长度,指定最大长度、最小长度以及错误消息
举例:[StringLength(30, ErrorMessage = "{0}长度必须在{2}至{1}个字符间", MinimumLength = 6)]
3、RegularExpression
说明:正则表达式匹配,匹配失败引发异常;
举例:[RegularExpression("^[A-Za-z0-9_]+$",ErrorMessage="密码必须是字母、数字或下划线")]
4、Range
说明:数据大小范围,一般为数字类型属性;
举例:[Range(35,44,ErrorMessage="数据不能小于35也不能大于44")] //整型,最小35,最大44
5、Remote
说明:数据远程校验,Ajax数据请求
举例:[Remote("CheckUserExits", "SysAdmin", ErrorMessage = "该账号已存在")]
6、Compare
说明:匹配两个数据,内容不一致则引发错误
举例:[Compare("Password",ErrorMessage="新密码和确认密码不一致")]
7、Display
说明:现实属性名称
举例:[Display(Name="确认密码")]
三、使用说明
MVC数据校验分为2种方式,客户端校验和后台校验,使用的时候,需要配置webconfig文件;
1、配置web config
<add key="ClientValidationEnabled" value="true"/>
<add key="UnobtrusiveJavaScriptEnabled" value="true"/>
2、引用前台客户端JS验证还需在页面配置
2.1、引入JS和CSS文件
<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<script src="http://www.cnblogs.com/Scripts/jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="http://www.cnblogs.com/Scripts/jquery.validate.min.js" type="text/javascript"></script>
<script src="http://www.cnblogs.com/Scripts/jquery.validate.unobtrusive.min.js" type="text/javascript"></script>
2.2、页面添加:
@{
Html.EnableClientValidation();
}
2.3、页面Form窗体展示不能使用<form>....</form>,而是采用Html.BeginForm的方式进行
@using (Html.BeginForm())
{
<td align="right">@Html.LabelFor(model => model.AdminCode)</td>
<td>@Html.TextBoxFor(model => model.AdminCode, new { @class = "manager-from02" })</td>
<td>@Html.ValidationMessageFor(Model => Model.AdminCode)</td> }
另外有时候默认的样式,存在site.css不是我们需要的样式 ,我们可以效果默认样式,或者添加自定义Class;
四、使用举例
1、ViewModel代码块
public class AdminCreateViewModel:BaseViewModel
{
[Required]
[Display(Name="账号")]
[StringLength(,ErrorMessage="{0}长度在{2}至{1}个字符间",MinimumLength=)]
[Remote("CheckUserExits", "SysAdmin", ErrorMessage = "该账号已存在")]
public string AdminCode { get; set; } [Required]
[DataType(DataType.Password)]
[StringLength(, ErrorMessage = "{0}长度必须在{2}至{1}个字符间", MinimumLength = )]
[RegularExpression("^[A-Za-z0-9_]+$",ErrorMessage="密码必须是字母、数字或下划线")]
[Display(Name="新密码")] public string Password { get; set; }
[Display(Name="确认密码")]
[DataType(DataType.Password)]
[Compare("Password",ErrorMessage="新密码和确认密码不一致")]
public string ConfirmPassword { get; set; } [Required]
[Display(Name = "级别")]
public string PowerCode { get; set; } //管理员姓名
[Required]
[RegularExpression(@"^(\w|[\u4e00-\u9fa5])*$", ErrorMessage = "输入数据无效")]
[Display(Name = "姓名")]
public string Name { get; set; } //管理员电话
[DataType(DataType.PhoneNumber)]
[RegularExpression(@"(^(13[0-9]{9})|(15[89][0-9]{8})$)|(^(\s*)$)",ErrorMessage="电话号码格式不正确")]
[Display(Name = "电话")]
public string PhoneNo { get; set; }
//管理员Email
[Display(Name="邮箱")]
[DataType(DataType.EmailAddress)]
[RegularExpression(@"(\w*@\w*)|(^(\s*?)$)", ErrorMessage = "邮箱格式不正确")]
public string Email { get; set; }
//管理员所属单位
[Display(Name = "单位")]
[RegularExpression(@"(^(\w|[\u4e00-\u9fa5])*$)|(^(\s*)$)", ErrorMessage = "输入数据无效")]
public string Comp { get; set; }
//管理员所属部门
[Display(Name = "部门")]
[RegularExpression(@"(^(\w|[\u4e00-\u9fa5])*$)|(^(\s*)$)", ErrorMessage = "输入数据无效")]
public string Dep { get; set; }
//管理员所属职位
[Display(Name = "职位")]
[RegularExpression(@"(^(\w|[\u4e00-\u9fa5])*$)|(^(\s*)$)", ErrorMessage = "输入数据无效")]
public string JobPost { get; set; }
//管理员状态
public bool Disable { get; set; }
}
2、View代码块
@model WebMgr.Models.AdminCreateViewModel
@{
ViewBag.Title = "Create";
Layout = "~/Views/Shared/_Layout.cshtml";
Html.EnableClientValidation();
} <div align="center">
<div class="manager-daohang">
<div class="manager-daohang-04">@Html.ActionLink("管理员列表","Index","SysAdmin")</div>
<div class="manager-daohang-03">添加管理员</div>
</div>
<div>
@using (Html.BeginForm())
{ <input type="hidden" name="Disable" value="true"/>
<table width="100%" border="" cellpadding="" cellspacing="" class="manager-Table-01">
<tr>
<td align="right" width=""> </td>
<td width=""> </td>
<td> </td>
</tr>
<tr>
<td align="right">@Html.LabelFor(model => model.AdminCode)</td>
<td>@Html.TextBoxFor(model => model.AdminCode, new { @class = "manager-from02" })</td>
<td>@Html.ValidationMessageFor(Model => Model.AdminCode)</td>
</tr>
<tr>

<td>@Html.PasswordFor(model => model.ConfirmPassword, new { @class = "manager-from02" })</td>
<td>@Html.ValidationMessageFor(Model => Model.ConfirmPassword)</td>
</tr>
<tr>
<td align="right">@Html.LabelFor(model => model.PowerCode)</td>
<td>
<select name="PowerCode" class="manager-from02" id="PowerCode">

<option value="AD8456212">一级管理员</option>
<option value="AD5235864">二级管理员</option>
</select>
</td>
</tr>
<tr>
<td align="right">@Html.LabelFor(model => model.Name)</td>
<td>@Html.TextBoxFor(model => model.Name, new { @class = "manager-from02" })</td>
<td>@Html.ValidationMessageFor(Model => Model.Name)</td>
</tr>
<tr>
<td align="right">@Html.LabelFor(model => model.Comp)</td>
<td>@Html.TextBoxFor(model => model.Comp, new { @class = "manager-from02" })</td>
<td>@Html.ValidationMessageFor(Model => Model.Comp)</td>
</tr>
<tr>
<td align="right">@Html.LabelFor(model => model.Dep)</td>
<td>@Html.TextBoxFor(model => model.Dep, new { @class = "manager-from02" })</td>
<td>@Html.ValidationMessageFor(Model => Model.Dep)</td>

<td>@Html.TextBoxFor(model => model.PhoneNo, new { @class = "manager-from02" })</td>

</tr>
<tr>
<td> </td>
