验证消息未显示 .Net MVC

Question

我是 .net MVC 的新手。我正在尝试验证模型中的字段，但未显示 error 消息。虽然字段是红色的，但消息就是不显示。请看下面：

型号：

[Required(AllowEmptyStrings = false, ErrorMessage = "FirstName is required")]
[Display(Name = "First Name")]
public string FirstName { get; set; }

cshtml:

<div class="editor-field">
  @Html.EditorFor(model => model.FirstName)
  @Html.ValidationMessageFor(model => model.FirstName)
</div>

我错过了什么？

确保您已在视图中添加以下脚本

<script src='@Url.Content("~/Scripts/jquery-1.8.2.js")' type='text/javascript'></script>    
<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>

并从网络配置启用验证

<appSettings>
........
........
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>
