有人可以幫我解決客戶端驗證問題(MVC4 RC,VS2010)嗎? Intellisense未在jQuery.validator中顯示addMethod。當我運行該應用程序時,它會在此方法中引發javascript null錯誤。我想讓用戶輸入大於當前時間的時間。我CustomValidation.js文件看起來像這樣:客戶端驗證問題 - MVC 4 RC
/// <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;
});
這裏是自定義驗證屬性碼:
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
}
我已經加入了CustomValidation.js到BundleConfig.cs文件,如下所示: 公衆類BundleConfig(不知道這是否是正確的):
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(
"~/Scripts/modernizr-*"));
bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/site.css"));
bundles.Add(new StyleBundle("~/Content/themes/base/css").Include(
"~/Content/themes/base/jquery.ui.core.css",
"~/Content/themes/base/jquery.ui.resizable.css",
"~/Content/themes/base/jquery.ui.selectable.css",
"~/Content/themes/base/jquery.ui.accordion.css",
"~/Content/themes/base/jquery.ui.autocomplete.css",
"~/Content/themes/base/jquery.ui.button.css",
"~/Content/themes/base/jquery.ui.dialog.css",
"~/Content/themes/base/jquery.ui.slider.css",
"~/Content/themes/base/jquery.ui.tabs.css",
"~/Content/themes/base/jquery.ui.datepicker.css",
"~/Content/themes/base/jquery.ui.progressbar.css",
"~/Content/themes/base/jquery.ui.theme.css"));
bundles.Add(new ScriptBundle("~/bundles/customvalidation").Include(
"~/Scripts/CustomValidation.js"));
}
這可能不是問題,但您的驗證總是返回錯誤 – 2012-07-16 14:14:55
這是一個錯字。我只是更新了代碼。你知道它爲什麼在addMethod上拋出null錯誤嗎? – rk1962 2012-07-16 14:37:38
創建一個新的MVC 4/RC互聯網應用程序並使用F12工具來了解帳戶控制器/視圖(註冊,更改密碼等)中的驗證。這樣你可以找出爲什麼沒有加載jQuery。 – RickAndMSFT 2012-07-16 18:45:08
