[英]Jquery Validation Works with Default [Required] but not with custom class
基於以下鏈接: 多語言 - 數據注釋創建一系列類來翻譯數據注釋的文本。 服務器端的一切正常,但客戶端驗證不起作用。
如果我使用: [System.ComponentModel.DataAnnotations.Required] public string Name { get; set; }
[System.ComponentModel.DataAnnotations.Required] public string Name { get; set; }
客戶端驗證工作正常,但如果我使用:
[Infrastructure.Required]//My custom class public string Name { get; set; }
它僅適用於服務器端。
這是我目前使用的課程:
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)) };
}
}
}
我從這篇文章中得到了答案: validation-type-names-in-unobtrusive GetClientValidationRules方法是這樣的:
public IEnumerable GetClientValidationRules(System.Web.Mvc.ModelMetadata metadata, ControllerContext context)
{
var clientValidationRule = new ModelClientValidationRule()
{
ErrorMessage = FormatErrorMessage(ErrorMessage),
ValidationType = "required"
};
yield return new[] { clientValidationRule };
}
在Global.asax里面的Application_Start中:
DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(RequiredAttribute), typeof(RequiredAttributeAdapter));
DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(StringLengthAttribute), typeof(StringLengthAttributeAdapter));
