我有一个页面，允许管理员使用用户名和密码一次将多个用户添加到数据库中。我使用远程用户名检查，所以在我的帐户模型中我有这个：
public class RegisterModel
{
[Required]
[Display(Name = "User name")]
[System.Web.Mvc.Remote("doesUserNameExist", "Account", HttpMethod = "POST", ErrorMessage = "User name already exists. Please enter a different user name.")]
public string UserName { get; set; }
// ...etc
}
在我的帐户控制器中，我有这个：
[HttpPost]
public JsonResult doesUserNameExist(string UserName)
{
var user = Membership.GetUser(UserName);
return Json(user == null);
}
现在，这可以很好地在单个表单上运行，使用 mvc html 帮助程序创建一个用户。当我在字段中输入用户名时，会显示正在使用用户名的消息。但是在这种不使用 mvc 帮助程序，而不是纯 html 和 javascript 的表单上，它不会显示：
@model List<PicsWebApp.Models.UserRegisterModel>
@{
ViewBag.Title = "NewRep";
}
<div class="col-lg-12">
<h1>First-Time Setup</h1>
</div>
<legend></legend>
<div class="col-lg-12">
<h3>Add Representatives <small>You can add more representatives later</small></h3>
@using (Html.BeginForm("NewRep", "Admin", new { jobid = ViewData["jobid"] }, FormMethod.Post, new { @class = "form" }))
{
@Html.ValidationSummary(true)

我知道我必须向用户名输入字段添加验证属性，但我试过了，但它仍然不起作用。有任何想法吗？
