asp.net-mvc - 客户端验证未显示消息

Question

我有一个带有用于创建用户帐户的表单的 MVC4 Internet 应用程序。表单验证有效，但当输入验证失败时，不会显示错误消息。它仍然阻止提交，直到验证问题解决但没有文本

Razor View 表单

<h2>Create New Account</h2>
<fieldset>
    <legend></legend>
    @using (Html.BeginForm("CreateUser",null)){
        @Html.AntiForgeryToken()
        <table class="create">
            <tr>
                <td colspan="2"><b>New Account</b>
            </tr>
            <tr>
                <td>@Html.DisplayNameFor(model=>model.UserName)</td><td>@Html.TextBoxFor(model=>model.UserName)</td>
                <td>@Html.DisplayNameFor(model=>model.EmailAddress)</td><td>@Html.TextBoxFor(model=>model.EmailAddress)</td>
                <td><input type="submit" value="Create User" /></td>
            </tr>
        </table>
    }
</fieldset>
    @Html.ValidationSummary()

使用的包包括验证文件

bundles.Add(new ScriptBundle("~/bundles/asset").Include(
            "~/Scripts/jquery-{version}.js",
            "~/Scripts/jquery-ui-{version}.js",
            "~/Scripts/jquery.validate*",
            "~/Scripts/jquery.unobtrusive*"));

使用的Model是实体模型，我添加了一个partial类来注释验证需求

[MetadataType(typeof(UserProfileMetadata))]
public partial class UserProfile
{
    //Empty Class just required for adding class level attribute
}

public class UserProfileMetadata
{
    //Fields from user profile requiring annotations
    [EmailAddress]
    [Required]
    [Display(Name = "Email Address")]
    public string  EmailAddress { get; set; }

    [Required]
    public string UserName { get; set; }

}

验证工作但现在显示消息让我认为它一定是一个标记错误，但我看不到它。

在表单内移动 ValidationSummary 将修复它。

<h2>Create New Account</h2>
<fieldset>
    <legend></legend>
     @using (Html.BeginForm("CreateUser",null)){
        @Html.ValidationSummary()
        @Html.AntiForgeryToken()
        <table class="create">
            <tr>
                <td colspan="2"><b>New Account</b>
            </tr>
            <tr>
                <td>@Html.DisplayNameFor(model=>model.UserName)</td>    <td>@Html.TextBoxFor(model=>model.UserName)</td>
            <td>@Html.DisplayNameFor(model=>model.EmailAddress)</td><td>@Html.TextBoxFor(model=>model.EmailAddress)</td>
            <td><input type="submit" value="Create User" /></td>
        </tr>
    </table>
}
</fieldset>
