有没有人看到一个MVC3数据注释的日期验证，需要一个选定的日期等于或大于当前日期？
如果已经有第三方添加了很酷。我已经在使用DataAnnotationsExtensions，但不提供我正在寻找的内容。
这似乎没有任何参考。所以，希望有人已经解决了这个问题，然后再尝试重新创造轮子，并写下自己的定制验证器。
我已经尝试了Range，但需要2个日期，并且都必须是字符串格式的常量，例如[Range(typeof(DateTime)，“1/1/2011”，“1/1/2016”)]帮助。而DataAnnotationsExtensions Min验证器只接受int和double
更新已解决
感谢@BuildStarted这是我结束了，它的工作伟大的服务器端，现在客户端与我的脚本
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;
namespace Web.Models.Validation {
[AttributeUsage(AttributeTargets.Field | AttributeTargets.Property,AllowMultiple = false,Inherited = true)]
public sealed class DateMustBeEqualOrGreaterThanCurrentDateValidation : ValidationAttribute,IClientValidatable {
private const string DefaultErrorMessage = "Date selected {0} must be on or after today";
public DateMustBeEqualOrGreaterThanCurrentDateValidation()
: base(DefaultErrorMessage) {
}
public override string FormatErrorMessage(string name) {
return string.Format(DefaultErrorMessage,name);
}
protected override ValidationResult IsValid(object value,ValidationContext validationContext) {
var dateEntered = (DateTime)value;
if (dateEntered < DateTime.Today) {
var message = FormatErrorMessage(dateEntered.ToShortDateString());
return new ValidationResult(message);
}
return null;
}
public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata Metadata,ControllerContext context) {
var rule = new ModelClientCustomDateValidationRule(FormatErrorMessage(Metadata.DisplayName));
yield return rule;
}
}
public sealed class ModelClientCustomDateValidationRule : ModelClientValidationRule {
public ModelClientCustomDateValidationRule(string errorMessage) {
ErrorMessage = errorMessage;
ValidationType = "datemustbeequalorgreaterthancurrentdate";
}
}
}
在我的模特儿
[required] [DateMustBeEqualOrGreaterThanCurrentDate] public DateTime SomeDate { get; set; }
客户端脚本
/// <reference path="jquery-1.7.2.js" />
jQuery.validator.addMethod("datemustbeequalorgreaterthancurrentdate",function (value,element,param) {
var someDate = $("#SomeDate").val();
var today;
var currentDate = new Date();
var year = currentDate.getYear();
var month = currentDate.getMonth() + 1; // added +1 because javascript counts month from 0
var day = currentDate.getDate();
var hours = currentDate.getHours();
var minutes = currentDate.getMinutes();
var seconds = currentDate.getSeconds();
today = month + '/' + day + '/' + year + ' ' + hours + '.' + minutes + '.' + seconds;
if (someDate < today) {
return false;
}
return true;
});
jQuery.validator.unobtrusive.adapters.addBool("datemustbeequalorgreaterthancurrentdate");
解决方法
创建自定义属性。
public class CheckDateRangeAttribute: ValidationAttribute {
protected override ValidationResult IsValid(object value,ValidationContext validationContext) {
DateTime dt = (DateTime)value;
if (dt >= DateTime.UtcNow) {
return ValidationResult.Success;
}
return new ValidationResult(ErrorMessage ?? "Make sure your date is >= than today");
}
}
