添加MVC3非干扰式验证（addMinMax）

| 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验证程序表示形式： 
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\");
而且此js不起作用（没有例外...可能已死＆:)） 但这可以正常工作： 
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\");
它出什么问题了？错误在哪里？

    一年前，我在进行自定义非侵入式验证时遇到了一些困难。这是我想出的。我需要创建验证器来检查用户是否十八岁。 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;
        }
    }
    在模型中： 
            [Required]
        [DataType(DataType.DateTime)]
        [CustomEiteenthValidator]            
        public DateTime Birthday { get; set; }
    还有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，我像这样渲染文本框： 
    <%: 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>
