我编写了一个验证传入数据的代码。
所有内置验证(RequiredAttribute等)有效 ......
但是我自己的写了DateRangeAttribute 并没有触发帖子上的错误,帖子来到我的控制器:(。
覆盖的IsValid 方法发送回良好(错误)值,并且在服务器端,控制器正确地看到无效的ModelState,但客户端没有。< / p>
数据验证属性在浏览器上呈现为HTML:
我希望在所有数据真正有效之前避开帖子。
DateRangeAttribute
public class DateRangeAttribute : RangeAttribute
{
public DateRangeAttribute (string minimumYear)
:base(typeof(DateTime), minimumYear, DateTime.Now.Year.ToString())
{
}
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
var inputYear = value as int?;
var result = (inputYear != null && inputYear >= 1886 && inputYear <= DateTime.Now.Year);
return result ? ValidationResult.Success : new ValidationResult(GetErrorMessage());
}
private string GetErrorMessage()
{
return "The year must be greater than 1886 and lower than the actual year.";
}
public override string FormatErrorMessage(string name)
{
return string.Format(GetErrorMessage(), name);
}
}

答案 0 :(得分:1)
您还必须通过IClientValidatable
提供自定义客户端验证实施。因此,我建议你直接从ValidationAttribute继承,因为你必须改变几乎所有的东西
