我有这样的属性:
public class AgeRangeAttribute:ValidationAttribute,IClientValidatable
{
public int MinAge { get; set; }
public int MaxAge { get; set; }
public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
{
ModelClientValidationRule rule = new ModelClientValidationRule
{
ErrorMessage = ErrorMessage,
ValidationType = "agerange"
};
if (MinAge != int.MinValue)
{
rule.ValidationParameters.Add("minage", DateTime.Now.AddYears(-MinAge).ToShortDateString());
}
if(MaxAge != int.MinValue)
{
rule.ValidationParameters.Add("maxage", DateTime.Now.AddYears(-MaxAge).ToShortDateString());
}
yield return rule;
}
}
和JS验证器表示:
jQuery.validator.addMethod("agerangemin", function (value, element, param) {
var date = setDate(new Date(),value);
var expected = setDate(new Date(), param);
return date <= expected;
});
jQuery.validator.addMethod("agerangemax", function (value, element, param) {
var date = setDate(new Date(), value);
var expected = setDate(new Date(), param);
return date > expected;
});
jQuery.validator.addMethod("agerangemaxmin", function (value, element, param) {
var date = setDate(new Date(), value);
var expectedMin = setDate(new Date(), param[1]);
var expectedMax = setDate(new Date(), param[0]);
return date <= expectedMin && date > expectedMax;
});
jQuery.validator.unobtrusive.adapters.addMinMax("agerange", "agerangemin", "agerangemax", "agerangemaxmin");
并且这个js不起作用(没有例外......可能已经死了&amp; :))
但这很好用:
jQuery.validator.addMethod("agerange", function (value, element, param) {
var date = new Date();
date = setDate(date, value);
var expected = setDate(new Date, param);
return date <= expected;
});
jQuery.validator.unobtrusive.adapters.addSingleVal("agerange", "minage");
它有什么问题吗?错误在哪里?
答案 0 :(得分:0)
一年前我在自定义不显眼验证方面遇到了一些困难。这就是我想出的。我需要创建验证器,检查用户是否已满十八岁。
我的代码:
public class CustomEiteenthValidator : ValidationAttribute, IClientValidatable
{
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
if (value == null) return null;
DateTime date = Convert.ToDateTime(value);
var minDate = DateTime.Now.AddYears(-18);
if (date > minDate)
return new ValidationResult("Employee should be more than 18 years");
return null;
}
public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
{
var rule = new ModelClientValidationRule()
{
ValidationType = "eiteenth",
ErrorMessage = "Employee should be more than 18 years"
};
var date = DateTime.Now.AddYears(-18);
rule.ValidationParameters["date"] = String.Format("{0:dd/MM/yyyy}", date).Replace('.', '/');
yield return rule;
}
}
模特:
[Required]
[DataType(DataType.DateTime)]
[CustomEiteenthValidator]
public DateTime Birthday { get; set; }
CustomDateValidation.js中的一些java脚本代码:
function isFormValid() {
var valid = true;
$('.field-validation-error').each(function () {
valid = false;
});
return valid;
}
(function ($) {
$.validator.addMethod("eiteenthcheck", function (val, elem, params) {
if (!val) {
return false;
}
try {
var birthday = $.datepick.parseDate("dd/mm/yyyy", val);
var maxBirthday = $.datepick.parseDate("dd/mm/yyyy", $(elem).attr('data-val-eiteenth-date'));
}
catch (e) {
return false;
}
if (maxBirthday.getTime() > birthday.getTime()) return true;
return false;
});
$.validator.unobtrusive.adapters.add("eiteenth", ["date"], function (options) {
options.rules["eiteenthcheck"] = 'eiteenthcheck';
if (options.message) options.messages["eiteenthcheck"] = options.message;
});
} (jQuery));
在视图中我渲染文本框:
<%: Html.EditorFor(model => model.Birthday) %>
<%: Html.ValidationMessageFor(model => model.Birthday) %>
最后一个是我使用的脚本:
<script src="<%= Url.Content("~/Scripts/jquery-1.7.1.min.js") %>" type="text/javascript"></script>
<script src="<%= Url.Content("~/Scripts/jquery.validate.js") %>" type="text/javascript"></script>
<script src="<%= Url.Content("~/Scripts/jquery.validate.unobtrusive.js") %>" type="text/javascript"></script>
<script src="<%= Url.Content("~/Scripts/jquery.datepick.js") %>" type="text/javascript"></script>
<script src="<%= Url.Content("~/Scripts/CustomDateValidation.js") %>" type="text/javascript"></script>
