Question

我正在尝试检查我的应用程序中是否采用了CustomUrl。问题是，当我单击提交按钮时，没有任何反应。我很难理解我做错了什么。

澄清：没有javascript错误，页面没有提交。对我来说，任何地方都没有任何错误。此外，如果我从AccountViewModel中删除 [Remote] 部分，因此它不会尝试进行检查，页面将提交，它也会在数据库中记录该值。所以我相当肯定它与我试图实施的验证有关。

以下是代码：

MembersController.cs

public JsonResult IsCustomUrlInUse(string customUrl)
{
    return Json(!UserManager.Users.Any(x => x.CustomUrl == customUrl), JsonRequestBehavior.AllowGet);
}

AccountViewModel.cs

[Required]
[StringLength(20, MinimumLength = 3)]
[Display(Name = "Custom URL")]
[Remote("IsCustomUrlInUse", "Members", ErrorMessage="Custom Url is already in use.  Please choose another.")]
public string CustomUrl { get; set; }

Register.cshtml

@model Azularis.System.Events.Models.RegisterViewModel
@{
    ViewBag.Title = "Register";
}

<h2>@ViewBag.Title.</h2>
<script src="~/Scripts/jquery-1.10.2.js"></script>
<script src="~/Scripts/jquery.validate.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.js"></script> 

@using (Html.BeginForm("Register", "Members", FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
{
    @Html.AntiForgeryToken()
    <h4>Create a new account.</h4>
    <hr />
    @Html.ValidationSummary("", new { @class = "text-danger" })
    <div class="form-group">
        @Html.LabelFor(m => m.CustomUrl, new { @class = "col-md-2 control-label"})
        <div class="col-md-10">
            @Html.TextBoxFor(m => m.CustomUrl, new { @class = "form-control"})
        </div>
    </div>
    <div class="form-group">
        <div class="col-md-offset-2 col-md-10">
            <input type="submit" class="btn btn-default" value="Register" />
        </div>
    </div>
}

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

编辑：

在评论中回答问题：

“开发者”选项中的“网络”选项卡正在捕获“自定义URL”字段的条目。
当我删除Remote时，最小字符的验证会启动并显示错误。此外，即使Remote在那里，最小字符限制仍然有效。

网络标签示例：http://postimg.org/image/8e2e1hesx/

我还在视图中删除了捆绑包，以确保由于重复而没有发生这种情况，但仍然会发生同样的事情。

编辑2：我在IsCustomUrlInUse方法中添加了一个Logging行，但它永远不会被触发。是不是我需要启用json调用服务器？因为MVC阻止json调用，直到我在某个地方的设置中启用它？

编辑3：

我设法产生了这个错误，我不知道我怎么也无法复制它，但也许这会有所帮助：
