如何使用依赖字段的验证在MVC3 [英] how can i use dependency fields validation in MVC3
问题描述
我用一类的字段验证属性,有这样的要求:
如果场'一'是验证成功,然后处理领域'B',但如果字段'A'是不是扔验证,忽略场B的验证确认。结果
它是可行的或者我应该想其他办法吗?
I use the validation attribute on the fields of a class and has a requirement like that:
if field 'a' is validate succeed then process the validation of field 'b' but if the field 'a' is not throw validation , ignore the validation of field 'b'.
does it feasible or i should think in other way?
public class myclass
{
[required]
public string a{get;set;}
[required]
public string b{get;set;]
}
我想:
1.如果一个通过验证,然后执行乙方的验证
2.如果一个没有通过验证,那么不执行乙方的验证
i want: 1.if a pass the validate, then execute b 's validate 2.if a not pass the validate , then don't execute the b 's validate

它包含了这两个验证,这将帮助你。
It contains these two validations that will help you out.
- RequiredIfAttribute。此属性说这个领域是必需的,如果一些其他字段值X。它被用作[RequiredIf(OtherField,TargetValue)]
- RequiredEmptyIfAttribute。此属性说如果一些其他字段值X这一领域必须是空的。它被用作[RequiredEmptyIf(OtherField,TargetValue)]
