Question

我与我的协会有麻烦。 NET MVC 3 application. 我的模型有2个特性,根据这个模式,我只想其中1个,我认为这1个是空的。例如,如果我进入电话号码,那么电子邮件就不再需要,反之亦然。

[Display(Name = "Contact Phone Number:")]
[MaxLength(150)]
public string ContactPhoneNumber { get; set; }

[Display(Name = "Contact Email Address:")]
[MaxLength(100)]
public string ContactEmailAddress { get; set; }

我是否需要建立一种习俗归属,以验证我的模式,如果是,我如何做到这一点?

Answer 1

页: 1 目标关于您的类别,并提供符合您习惯逻辑的<代码>Validate(>方法。如果你倾向于确保提供一种服务,则按客户的习俗验证逻辑确定这一点。我认为,这比执行一个特性更容易。

public class ContactModel : IValidatableObject
{
   ...

   public IEnumerable<ValidationResult> Validate( ValidationContext context )
   {
        if (string.IsNullOrWhitespace( ContactPhoneNumber ) 
            && string.IsNullOrWhitespace( ContactEmailAddress ))
        {
             yield return new ValidationResult( "Contact Phone Number or Email Address must be supplied.", new [] { "ContactPhoneNumber", "ContactEmailAddress" } );
        }
   }
}

为了在客户方面进行一切工作,你认为有必要在你看来添加以下文字:

<script type="text/javascript">
$(function() {
    $( form ).validate(); 
    $( form ).rules( add , { 
        "ContactPhoneNumber": { 
            depends: function(el) { return !$( #ContactEmailAddress ).val(); } 
        } 
    });
});
</script>

Answer 2

可使用

[RequiredIf("ContactPhoneNumber == null",
    ErrorMessage = "At least email or phone should be provided.")]
public string ContactEmailAddress { get; set; }

[RequiredIf("ContactEmailAddress == null",
    ErrorMessage = "At least email or phone should be provided.")]
public string ContactPhoneNumber { get; set; }

Answer 4

I know you already have a solution, but I had a similar situation, so maybe my solution will prove helpful to someone else. I implemented a custom attribute with client-side validation. Here is my blog post: http://hobbscene.com/2011/10/22/conditional-validation/
