MVC 3远程验证提交时出现jQuery错误

Question

在我的项目中，我似乎对远程验证有一个奇怪的问题。我正在对电子邮件字段进行简单的验证检查，以确保它是唯一的。

我注意到，除非我把光标放到文本框中，然后在提交表单之前删除它至少触发验证一次，否则我将得到一个javascript错误。

e[h] is not a function jquery.min.js line 3 

如果我尝试重新提交表单返回上面的错误后，一切正常。这几乎就像在等待验证返回之前尝试提交的表单或其他东西。

我是否需要在提交表单前静静地提交远程验证请求？

下面是我正在使用的代码的快照:(我也试过GET而不是POST，但是我得到了相同的结果）。如上所述，代码工作正常，但表单返回一个jquery错误，除非验证触发至少一次。

型号：

public class RegisterModel 
    { 
     [Required] 
     [Remote("DoesUserNameExist", "Account", HttpMethod = "POST", ErrorMessage = "User name taken.")] 
     [Display(Name = "User name")] 
     public string UserName { get; set; } 

     [Required] 
     [Display(Name = "Firstname")] 
     public string Firstname { get; set; } 

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

     [Required] 
     [Remote("DoesEmailExist", "Account", HttpMethod = "POST", ErrorMessage = "Email taken.", AdditionalFields = "UserName")] 
     [Display(Name = "Email address")] 
     public string Email { get; set; } 

     [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)] 
     [DataType(DataType.Password)] 
     [Display(Name = "Password")] 
     public string Password { get; set; } 

     [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)] 
     [DataType(DataType.Password)] 
     [Display(Name = "Confirm password")] 
     public string ConfirmPassword { get; set; } 

     [Display(Name = "Approved?")] 
     public bool IsApproved { get; set; } 
    } 

public class UserRoleModel 
    { 
     [Display(Name = "Assign Roles")] 
     public IEnumerable<RoleViewModel> AllRoles { get; set; } 
     public RegisterModel RegisterUser { get; set; } 
    } 

控制器：

// POST: /Account/DoesEmailExist 
    // passing in username so that I can ignore the same email address for the same user on edit page 

    [HttpPost] 
    public JsonResult DoesEmailExist([Bind(Prefix = "RegisterUser.Email")]string Email, [Bind(Prefix = "RegisterUser.UserName")]string UserName) 
    { 
     var user = Membership.GetUserNameByEmail(Email); 
     if (!String.IsNullOrEmpty(UserName)) 
     { 
      if (user == UserName) 
       return Json(true); 
     } 
     return Json(user == null); 
    }

这里的问题是完全一样的狗在评论中提到以上。设置表单名称和ID为我解决了这个错误。

因此，基于上面的代码，我取代了看法与此BeginForm部分：

@using (Html.BeginForm("Edit", "Account", FormMethod.Post, new { id = "editForm", name = "editForm" }))
