Jquery 验证适用于默认 [必需] 但不适用于自定义 class

Jquery Validation Works with Default [Required] but not with custom class

基于以下 link:Multi Language - Data Annotations 制作一系列 classes 来翻译数据注释的文本。 服务器端一切正常,但客户端验证不起作用。

如果我使用:[System.ComponentModel.DataAnnotations.Required] public string Name { get; set; }

客户端的验证工作正常,但如果我使用:

[Infrastructure.Required]//My custom class public string Name { get; set; }

它只适用于服务器端。

这是我目前使用的class:

namespace project.Infrastructure
{
public class RequiredAttribute : System.ComponentModel.DataAnnotations.RequiredAttribute
{
    private string _displayName;
    public RequiredAttribute()
    {
        ErrorMessageResourceName = "Validation_Required";
    }
    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {
        _displayName = validationContext.DisplayName;
        return base.IsValid(value, validationContext);
    }
    public override string FormatErrorMessage(string name)
    {
        var msg = WebsiteTranslations.GetTranslationErrorMessage(Settings.LanguageId, "Required", WebsiteTranslations.GetTranslation(name, 1, Settings.LanguageId));
        return string.Format(msg, _displayName);
    }
    public System.Collections.IEnumerable GetClientValidationRules(System.Web.Mvc.ModelMetadata metadata, ControllerContext context)
    {
        return new[] { new ModelClientValidationRequiredRule((ErrorMessage)) };
    }
  }
}

我从这个post得到答案: GetClientValidationRules 方法是这样的:

    public IEnumerable GetClientValidationRules(System.Web.Mvc.ModelMetadata metadata, ControllerContext context)
    {
        var clientValidationRule = new ModelClientValidationRule()
        {
            ErrorMessage = FormatErrorMessage(ErrorMessage),
            ValidationType = "required"
        };
        yield return new[] { clientValidationRule };
    }

而在Application_Start里面Global.asax:

      DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(RequiredAttribute), typeof(RequiredAttributeAdapter));
        DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(StringLengthAttribute), typeof(StringLengthAttributeAdapter));
