HtmlHelper用法大全3:编辑用户信息（Html.LabelFor、Html.EditorFor、Html.RadioButtonFor、Html.CheckBoxFor）

@Html.***For:为由指定表示式 表示对象中的 每个属性，返回对应html

示例效果：



 

一、设置通用的验证方法

         Models层

public class MyStringIsChineseAttribute: ValidationAttribute
{
#region 验证中文
private bool _myreturn = false;
public bool myNullDefVal
{
get { return _myreturn; }
set { _myreturn = value; }

}
//覆盖父类方法（确定对象的指定值是否有效）
public override bool IsValid(object value)
{
if (value == null) return _myreturn;
return Regex.IsMatch(value.ToString(), @"^[\u4e00-\u9fa5]{0,}$", RegexOptions.IgnoreCase);
}
//覆盖父类方法（基于发生错误的数据字段对错误消息应用格式设置）
public override string FormatErrorMessage(string name)
{
return "非中文字符！";
}
#endregion
}

        Controller层

public class MyValidDataController : Controller
{
/// <summary>
/// 姓名验证，只能是中文
/// </summary>
/// <param name="ExamineeName">姓名</param>
/// <returns></returns>
public JsonResult ExamineeNameCheck(string XM)
{
MyStringIsChineseAttribute ff = new MyStringIsChineseAttribute();
bool myidexist = ff.IsValid(XM);
if (!myidexist)
{
return Json("姓名只能是中文！", JsonRequestBehavior.AllowGet);
}
else
{
return Json(true, JsonRequestBehavior.AllowGet);
}
}

}

 

 

二、Person类（Models层）

public class Person
{
#region  属性定义
[Display(Name = "姓名")]
[Required(ErrorMessage="{0}不能为空.")]
[StringLength(4, MinimumLength = 2, ErrorMessage = " {0} 最少 {2} 字符,最多{1}字符。")]
[Remote("ExamineeNameCheck", "MyValidData")]//服务端参与的验证(注意:ExamineeNameCheck方法的参数名必须叫XM)
//[RegularExpression(@"^[\u4e00-\u9fa5]{0,}$",ErrorMessage = "只能输入汉字")]//正则表达式
public string XM{ get; set; }

[Display(Name = "性别")]
public bool XB { get; set; }

[Display(Name = "爱好1")]
public bool AH1 { get; set; }

[Display(Name = "爱好2")]
public bool AH2 { get; set; }

[Display(Name = "学历")]
public string XL { get; set; }

[Display(Name = "备注")]
public string BZ { get; set; }
#endregion
}

 

三、Controller层

public class TestController : Controller
{
public ActionResult Index()
{
Person person = new Person();
person.XM = "小张";
person.XB = false;
person.AH2 = true;

List<SelectListItem> lists = new List<SelectListItem>
{
new SelectListItem{Text="大学",Value="大学"},
new SelectListItem{Text="高中",Value="高中"},
new SelectListItem{Text="初中",Value="初中"}
};
ViewData["XlList"] = lists;
person.XL = "高中";

person.BZ = "备注";
return View(person);
}

[HttpPost]
public ActionResult Index(Person person,FormCollection fc)
{
//注意防止页面反复提交
string str = "";
if (ModelState.IsValid)//模型状态字典实例有效
{
               //一、验收数据的合法性
               //1、AJAX实现客户端数据验证(在数据被送到后台前，我们应该先进行一遍验证，这样可以节约很多资源)           
//2、同步方式完成数据验证
               if (String.IsNullOrEmpty(person.XM))
               {
                  ViewData.ModelState.AddModelError("XM", "姓名不能为空！");
                  return Index();//返回Index方法
               }
str += "姓名:" + person.XM + "<br>";
str += "性别:" + person.XB + "<br>";
str += "爱好1:" + person.AH1 + "<br>";
str += "爱好2:" + person.AH2 + "<br>";
str += "学历：" + person.XL + "<br>";
str += "备注：" + person.BZ + "<br>";
}
return Content(str);
}
}

 

四、Views层

@model MvcApplication4.Models.Person

@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>编辑用户信息</h2>

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

@using (Html.BeginForm()) {
@Html.ValidationSummary(true)

<div>
@Html.LabelFor(model => model.XM)
@Html.EditorFor(model => model.XM)
@Html.ValidationMessageFor(model => model.XM)
</div>
<div>
@Html.LabelFor(model=>model.XB)
@Html.RadioButtonFor(model => model.XB, true)男
@Html.RadioButtonFor(model => model.XB, false)女
@Html.ValidationMessageFor(model => model.XB)
</div>
<div>
@Html.LabelFor(model => model.AH1)
@Html.CheckBoxFor(model => model.AH1)

@Html.LabelFor(model => model.AH2)
@Html.CheckBoxFor(model=>model.AH2)
</div>
<div>
@Html.LabelFor(model => model.XL)
@Html.DropDownListFor(model => model.XL, ViewData["XlList"] as IEnumerable<SelectListItem>)
</div>
<div>
@Html.LabelFor(model => model.BZ)
@Html.TextAreaFor(model=>model.BZ,3,30,null)
</div>
<div>
<input type="submit" value="保存" name="tj"/>
</div>
}

多选框绑定：

@Html.CheckBoxList("Platform", (ViewBag.Platforms as List<Guoany.Basic.Models.SysParametersDetailInfo>).ToDictionary(m => m.ParamDetailCode, m => m.ParamDetailValue).ToSelectList(), new { @class = "txt" })
