我建立了习俗验证属性。

[AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, AllowMultiple = false, Inherited = true)]
    public sealed class ValidateDublicateNameAttribute : ValidationAttribute, IClientValidatable
    {
        private const string _defaultErrorMessage = "Library with title {0} is already exist";
        private UnitOfWork unit = new UnitOfWork();

        public ValidateDublicateNameAttribute()
            : base(_defaultErrorMessage)
        {
        }
        public override s

tring FormatErrorMessage(string name) { return String.Format(ErrorMessageString, name); }

    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {
        string valueAsString = value as string;
        ValidationResult result = ValidationResult.Success;
        if (String.IsNullOrEmpty(valueAsString))
        {
            if (unit.ResourceSrvc.GetLibraryByTitle(valueAsString) != null)
            {
                result = new ValidationResult(String.Format(_defaultErrorMessage,value));
            }
        }
        else
        {
            result = new ValidationResult("Title cant be empty or null");
        }
        return result;
    }

    public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
    {
        var rule = new ModelClientValidationRule
        {
            ErrorMessage = this.ErrorMessage,
            ValidationType = "dublicatename",
        };
        yield return rule;
    }
}

并且利用模型对我的模型进行校正

public class ResourceLibraryModel
{
    public Guid LibraryId { get; set; }
    [Required]
    [ValidateDublicateName(ErrorMessage="title cant dublicate")]
    public string Title { get; set; }
}

在客户方面,我

<script src="/Scripts/jquery.validate.min.js" type="text/javascript"></script>
<script src="/Scripts/jquery.validate.unobtrusive.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function () {

        $.validator.addMethod("dublicatename", function (value, element, params) {
            alert("test");
        });

    });
</script>

我没有任何验证参数,也没有打字笔字。

服务器侧验证完全可行,但客户方不可行。

任何想法?

这一观点

     @using (Ajax.BeginForm("CreateLibrary", "Resource", new AjaxOptions { OnSuccess = "RequestSucceeded"}))
        {
            @Html.ValidationSummary(true, "Account creation was unsuccessful. Please correct the errors and try again.")
                <div>
                    @*<div style="margin-bottom:15px">
                        <label><b>Library information:</b></label>
                    </div>*@

                    <div class="editor-field">
                        @Html.TextBoxFor(m => m.Title, new { @class = "logon-field" })
                        @Html.ValidationMessageFor(m => m.Title)
                    </div>
                    <div class="editor-label">
                        @Html.LabelFor(m => m.Title)
                    </div>
                 </div>
}
