在过去的两天里，我一直在尝试让客户端自定义验证在 ASP.Net MVC3 上工作。我已经按照此处、此处、此处和此处的示例进行操作，但无法使其运行。有人可以看看我的（当前）代码，如果您发现任何错误，请告诉我，任何帮助将不胜感激

Web.Config 将 ClientValidationEnabled 和 UnobtrusiveJavaScriptEnabled 都设置为 true

_Layout.cshtml 引用文件如下

<script src="@Url.Content("~/Scripts/jquery-1.7.2.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/DateFormatValidator.js")" type="text/javascript"></script>

服务器端验证类定义如下

public class DateFormatValidation : ValidationAttribute, IClientValidatable
{
    public string ValidDateFormat { get; set; }

    public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
    {
        var modelClientValidationRule = new ModelClientValidationRule
        {
            ValidationType = "validatedate",  // the name of the validation rule as specified in DateFormatValidator.js
            ErrorMessage = LocalisationStrings.InvalidDateFormat
        };

        modelClientValidationRule.ValidationParameters["name"] = ValidDateFormat;
        yield return modelClientValidationRule;
    }

    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {            
        var dateString = (string) value;
        if(String.IsNullOrEmpty(dateString))
        {
            return ValidationResult.Success;
        }

        // if we can't convert to a date based on the current culture then we will get a null back from the ConvertLocalDateFormatToISO extension method
        if(String.IsNullOrEmpty(dateString.ConvertLocalDateFormatToISO()))
        {
            return new ValidationResult(LocalisationStrings.InvalidDateFormat);
        }
        return ValidationResult.Success;
    }
}

视图模型定义如下

public class SearchViewModel : ElectronicDocument
{

    #region Properties

    [DateFormatValidation(ValidDateFormat="validatedate")] // addig the paramter to the attribute is just a test to get this to work
    public string DueDateFrom
    {
        get;            
        set;             
    }

    [DateFormatValidation]
    public string DueDateTo
    {
        get;
        set;             
    }

客户端验证脚本如下：

(function ($) {
$.validator.addMethod('validatedateformat', function (value, element, param) {
    if (!value) { return true; }
    try {
        var isValidDate = false;
        /* - CheckDateValidFormat is available from the base controller class  */
        $.get('CheckDateValidFormat(' + value +')',
            function (data) {                  
                isValidDate = data;
            });
        if (isValidDate) {
            return true;
        }
        return false;
    }
    catch (e) {
        return false;
    }
});

$.validator.unobtrusive.adapters.add('validatedate', ['name'], function (options) {
    options.rules["validatedateformat"] = options.params.name;
    if (options.message) options.messages["validatedateformat"] = options.message;
});

} (jQuery));

最后，视图如下所示：

<td style="font-size:10px; white-space:nowrap; color: #666">               
           @Html.TextBox("DocumentDateFrom", Model.DocumentDateFrom, new { @class = "date", style = "width:90px;" })
        to @Html.TextBox("DocumentDateTo", Model.DocumentDateTo, new { @class = "date", style = "width:90px;" })</td>

你包括jquery-1.8.11.min.js. 这个版本的 jQuery 不存在，因为最新版本是 1.7.2。

我怀疑您包含jQuery UI（最新版本 1.8.20）并且您认为那是jQuery。确保您使用的是正确的文件。
