使用MVC 4和KnockoutJS.我可以使用自定义敲除绑定绑定不显眼的验证吗？我目前正在使用模板重新绑定验证afterRender.我很乐意让它自动添加绑定.像这样:

ko.bindingHandlers.egtZipRep = {
    init: function (element, valueAccessor, allBindingsAccessor, context) {
      $(element).inputmask("99999", { "placeholder": "?" });
      egtUniqueNameBinding(element, ++ko.bindingHandlers['uniqueName'].currentIndex);

      applyValidationRules(element); // Is it possible to do this here?

      ko.bindingHandlers.value.init(element, valueAccessor, allBindingsAccessor, context);
    }
};

我整天都在修整它.如果不是非常低效,我就做不到.

我目前这样做的方式如下.也许我应该对此感到高兴.但我猜之前有人试过这个.

self.ReferenceAfterRender = function (element) {
    bindUnobtrusiveValidation(element);
}

// Bind validation on new content
function bindUnobtrusiveValidation(element) {
   // Bind to fields - must be called everytime new field is created
   $.validator.unobtrusive.parseDynamicContent(element);
}

$.validator.unobtrusive.parseDynamicContent = function (selector) {
// Use the normal unobstrusive.parse method …

我已经尝试了几件事，但无法使其正常工作。我需要排除邮政信箱。我以为我只需要用 ?!.. 包裹它，但它不起作用。有什么想法吗？

^((?i)[P|p]*(OST|ost)*\.*\s*[O|o|0]*(ffice|FFICE)*\.*\s*[B|b][O|o|0][X|x]\s*(\d.))*$

编辑：对不起，这就是我要找的。

示例：当输入是“邮政信箱”或“邮局”时，我需要正则表达式为假。当输入为 7821 Test street 时，我需要正则表达式为真。

我试图在 ASP.net MVC 项目中使用它

/// <summary>
/// Regex for street fields
/// </summary>
[AttributeUsage(AttributeTargets.Property | AttributeTargets.Field, AllowMultiple =     false)]
public class StreetAddressAttribute : RegularExpressionAttribute, IClientValidatable
{
/// <summary>
/// Regular expression validation for street field
/// </summary>
public StreetAddressAttribute()
  : base(@"^(?!(?i)[P|p]*(OST|ost)*\.*\s*[O|o|0]*(ffice|FFICE)*\.*\s*[B|b][O|o|0][X|x]\s*(\d.)*)$")
{
}

 /// <summary>
 /// Client side validation
 /// </summary>
 /// <param name="metadata">Modelmetadata</param>
 /// <param name="context">ControllerContext</param>
 /// <returns>Client-side validation rules</returns>
 public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata    metadata, ControllerContext context)
 {
   yield return …
