一、web.config加入
<appSettings>
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>
二、Controllers验证方法
using System;
using System.Globalization;
using System.Web.Mvc;
using System.Web.UI;
using Mvc3RemoteVal.Models;
namespace Mvc3RemoteVal.Controllers {
[OutputCache(Location = OutputCacheLocation.None, NoStore = true)] //清除缓存
public class ValidationController : Controller {
/// <summary>
/// 检验商家昵称是否已存在
/// </summary>
/// <param name="sellerNick">昵称</param>
/// <returns>bool</returns>
public JsonResult CheckSellerNick(string sellerNick)
{
bool isValidate = false;
if (!SellerAccess.CheckSellerNick(sellerNick))
{
isValidate = true;
}
return Json(isValidate, JsonRequestBehavior.AllowGet);
}
}
}
三、model
public class CreateUserModel : EditUserModel {
[Required]
[StringLength(6, MinimumLength = 3)]
[Remote("CheckSellerNick", "Seller",ErrorMessage="该昵称已存在")]//ActionName,Controller,错误信息
[RegularExpression(@"(/S)+", ErrorMessage = "White space is not allowed.")]
[Editable(true)]
public override string UserName { get; set; }
}
