我已实现postDelayed()，没有任何问题：
IValidatableObject但是，这仅在“验证摘要”中显示错误消息。我也想让这个错误使焦点集中在指定的 public class DisclaimerCBs : IValidatableObject
{
public bool cb1 { get; set; } = false;
public bool cb2 { get; set; } = false;
public bool cb3 { get; set; } = false;
public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
Type type = validationContext.ObjectInstance.GetType();
IEnumerable<PropertyInfo> checkBoxeProperties = type.GetProperties(BindingFlags.Instance | BindingFlags.Public).Where(p => p.PropertyType == typeof(bool));
bool allIsChecked = true;
foreach (PropertyInfo checkBoxProperty in checkBoxeProperties)
{
var isChecked = (bool)checkBoxProperty.GetValue(validationContext.ObjectInstance);
if (!isChecked)
{
allIsChecked = false;
break;
}
}
if(!allIsChecked)
yield return new ValidationResult("Please agree to all Disclaimers. ");
//TRUE IF THIS FAR
yield return ValidationResult.Success;
}
}
元素上，并在标签中重申该错误，就像属性验证器使用<div>一样。我该怎么办？
答案 0 :(得分：1)
用以下内容替换您的public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
Type type = validationContext.ObjectInstance.GetType();
IEnumerable<PropertyInfo> checkBoxeProperties = type.GetProperties(BindingFlags.Instance | BindingFlags.Public).Where(p => p.PropertyType == typeof(bool));
List<ValidationResult> validationResult = new List<ValidationResult>();
foreach (PropertyInfo checkBoxProperty in checkBoxeProperties)
{
var isChecked = (bool)checkBoxProperty.GetValue(validationContext.ObjectInstance);
if (!isChecked)
{
validationResult.Add(new ValidationResult("Please agree to this Disclaimer.", new[] { checkBoxProperty.Name }));
}
}
return validationResult;
}
方法：
$composer.phar
$export PATH=/usr/local/php5/bin:$PATH
$composer.phar --version
