誰かがクライアント検証の問題(MVC4 RC、VS2010)を手伝ってくれますか?IntellisenseはjQuery.validatorにaddMethodを表示していません。アプリケーションを実行すると、このメソッドでjavascriptnullエラーがスローされます。ユーザーが現在の時刻よりも長い時刻を入力できるようにしたい。私のCustomValidation.jsファイルは次のようになります。
/// <reference path="jquery-1.7.2-vsdoc.js" />
/// <reference path="jquery.validate-vsdoc.js" />
/// <reference path="jquery.validate.unobtrusive.js" />
jQuery.validator.addMethod('dategreaterthan', function (value, element, param) {
var today = new Date();
return Date.parse(value) > today;
});
$.validator.unobtrusive.adapters.add("dategreaterthan", function (options) {
options.rules["dategreaterthan"] = true;
options.messages["dategreaterthan"] = options.message;
});
カスタム検証属性コードは次のとおりです。
public class DateGreaterThanAttribute : ValidationAttribute, IClientValidatable
{
private const string DefaultErrorMessage = "{0} Time must be greater than current time";
public DateGreaterThanAttribute() :
base(DefaultErrorMessage)
{ }
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
ValidationResult validationResult = ValidationResult.Success;
if (((DateTime)value).TimeOfDay >= DateTime.Now.TimeOfDay)
return validationResult;
else
{
return new ValidationResult(FormatErrorMessage(this.ErrorMessage));
}
}
public override string FormatErrorMessage(string name)
{
return base.FormatErrorMessage(name);
}
#region IClientValidatable Members
public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
{
var rule = new ModelClientValidationRule();
rule.ErrorMessage = FormatErrorMessage(metadata.GetDisplayName());
rule.ValidationType = "dategreaterthan";
yield return rule;
}
#endregion
}
以下に示すように、CustomValidation.jsをBundleConfig.csファイルに追加しました。publicclass BundleConfig(正しいかどうかはわかりません):
public static void RegisterBundles(BundleCollection bundles)
{
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-1.*"));
bundles.Add(new ScriptBundle("~/bundles/jqueryui").Include(
"~/Scripts/jquery-ui*"));
bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
"~/Scripts/jquery.unobtrusive*",
"~/Scripts/jquery.validate*"));
bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(

}
