我有一个简单的模型是默认的RegisterModel
,在根据Create
的模型创建视图时,我最终拥有
public class RegisterModel
{
[Required]
[Remote("UserNameExists", "Account", "", ErrorMessage = "Username is already taken.")]
[Display(Name = "Username (spaces will be stripped, must be at least 6 characters long)")]
public string UserName { get; set; }
[Required]
[Editable(true)]
[Display(Name = "First and Last name")]
public string Name { get; set; }
[Required]
[DataType(DataType.EmailAddress, ErrorMessage = "You need to enter a valid email")]
[Remote("EmailExists", "Account", "", ErrorMessage = "Email is already taken.")]
[Display(Name = "Email address")]
public string Email { get; set; }
//[Required]
//[ValidatePasswordLength]
[DataType(DataType.Password)]
[Display(Name = "Create a password")]
public string Password { get; set; }
[DataType(DataType.Password)]
[Display(Name = "Verify password")]
//[Compare("Password", ErrorMessage = "Password's do not match.")]
public string ConfirmPassword { get; set; }
}
并在视图中:
<h3>
Details</h3>
@using (Html.BeginForm("GenerateBetaLink", "Account", FormMethod.Post, new { @id = "beta-user" }))
{
@Html.ValidationSummary(true)
<div>
<div class="editor-label">
@Html.LabelFor(model => model.UserName)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.UserName)
@Html.ValidationMessageFor(model => model.UserName)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Name)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Name)
@Html.ValidationMessageFor(model => model.Name)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Email)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Email)
@Html.ValidationMessageFor(model => model.Email)
</div>
<p>
</p>
<p>
<input type="submit" value="Create Beta User" class="btn-submit" />
<span class="loading"></span>
</p>
</div>
}
我的Validation Controller
public class ValidationController : Controller
{
public JsonResult UserNameExists(string UserName)
{
OnlineServicesRepository db = new OnlineServicesRepository();
var user = db.FindUserByUsername(UserName.Trim());
return user == null ?
Json(true, JsonRequestBehavior.AllowGet) :
Json(string.Format("{0} is not available.", UserName),
JsonRequestBehavior.AllowGet);
}
public JsonResult EmailExists(string Email)
{
OnlineServicesRepository db = new OnlineServicesRepository();
var user = db.FindUserByEmail(Email.Trim());
return user != null ?
Json(true, JsonRequestBehavior.AllowGet) :
Json(string.Format("{0} is not available.", Email),
JsonRequestBehavior.AllowGet);
}
}
我的问题,远程验证会触发,但不会将任何内容写入错误消息,因为它应该是jQuery方法.valid()
一直告诉我 表单有效:

我缺少什么?
MSDN article显示相同的代码(在可下载文件中)
答案 0 :(得分:7)
以下对我来说很好:
型号:
public class RegisterModel
{
[Required]
[DataType(DataType.EmailAddress, ErrorMessage = "You need to enter a valid email")]
[Remote("EmailExists", "Home", "")]
[Display(Name = "Email address")]
public string Email { get; set; }
}
控制器:
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(RegisterModel model)
{
return View(model);
}
public ActionResult EmailExists(string email)
{
if ((email ?? string.Empty).Contains("foo"))
{
return Json(email + " is not available", JsonRequestBehavior.AllowGet);
}
return Json(true, JsonRequestBehavior.AllowGet);
}
}
查看:
@model RegisterModel
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
@using (Html.BeginForm())
{
@Html.LabelFor(model => model.Email)
@Html.EditorFor(model => model.Email)
@Html.ValidationMessageFor(model => model.Email)
<input type="submit" value="OK" />
}

我遇到了同样的问题并通过更新到最新的jQuery(1.6)和jQuery.validate(1.8)库来解决它。获取这些内容的最简单方法是在NuGet中搜索jQuery。
