我已经为单个属性进行了客户端验证，但是，我想使用客户端验证在模型级别（2 个或更多属性）进行验证。

我@Html.ValidationSummary(true)用来显示我创建的 Model 属性的验证错误。

但是，当生成模型错误时，它不会显示消息。它会阻止执行操作，但不会显示错误。

有人知道为什么会这样吗？

我的预感是它与客户端验证有关，因为在这种情况下服务器端不起作用，因为我必须使用 Ajax 表单。

任何意见，将不胜感激！

模型属性

public class AuditDetailValidatorAttribute : ValidationAttribute, IClientValidatable
{
    public AuditDetailValidatorAttribute()
    {
        ErrorMessage = "Must select an NCN level...";
    }

    public override bool IsValid(object value)
    {
        AuditRequirementDetail audit = value as AuditRequirementDetail;

        if (audit == null || audit.AuditResult.Id == 0 || audit.AssessmentLevel.Id == 0)
        {
            return true;
        }
        else
        {
            return !(audit.AuditResult.Id == 4 && audit.AssessmentLevel.Id == 1);
        }
    }

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

模型类

    [AuditDetailValidator]
    public class AuditRequirementDetail
    {
        // Constructor
        public AuditRequirementDetail()
        {
            // instantiate the contained objects on AuditRequirementDetail creation
            AssessmentLevel = new AssessmentLevel();
            AuditResult = new AuditResult();
            Requirement = new RequirementDetail();
            Attachment = new Attachment();

            Counter = 0;
        }
        /* rest of the code */
     }

看法

@model pdiqc.Models.AuditRequirement.AuditRequirementDetail

@{
    var SuccessTarget = "success" + Model.DetailID;
    var IsValidTarget = "IsValid" + Model.DetailID;
    var PerformCompletedTarget = "PerformCompleted" + Model.DetailID;
    var AuditResultTarget = "AuditResult_Id" + Model.DetailID;
    var AssessmentLevelTarget = "AssessmentLevel_Id" + Model.DetailID;
    var DesignatorTarget = "Designator_Id" + Model.DetailID;
    var EvidenceTarget = "Evidence_Id" + Model.DetailID;
    var AttachmentTarget = "Attachments_Id" + Model.DetailID;

    var AuditResultReferral = "#" + AuditResultTarget;
    var AssessmentLevelReferral = "#" + AssessmentLevelTarget;
    var DesignatorReferral = "#" + DesignatorTarget;
    var EvidenceReferral = "#" + EvidenceTarget;
    var AttachmentReferral = "#" + AttachmentTarget;
}

    @using (Ajax.BeginForm("PerformRequirement", "Audit", new AjaxOptions { HttpMethod = "POST", OnSuccess = "success" }, new {Class="PerformReqForm" }))
    {
        @Html.ValidationSummary(true)
        if ((Model.AuditResult.Id == 1 && Model.AssessmentLevel.Id > 1) || Model.Evidence == string.Empty || Model.Evidence == null)
        {
            <input class="@IsValidTarget" name="IsValid" type="hidden" value=false />
        }
        else
        {
            <input class="@IsValidTarget" name="IsValid" type="hidden" value=true />
        }

       <p class="reqText">@Model.RequirementLabel.ConfigurableLabelDesc #@ViewBag.PerformCounter - @ModelMetadata.FromLambdaExpression(x => x.Requirement.Text, ViewData).SimpleDisplayText</p>
       <div class="hide">
       /* REST OF CODE */
    }

我为一个复选框编写了一个自定义验证器，以确保它被厚脸皮并且必须执行以下操作。

<script type="text/javascript">
    $(function() {
        $.validator.unobtrusive.adapters.addBool('requiredcheckbox', 'required');
    }(jQuery));
</script>

还包括 @Html.ValidationMessageFor(x=>x.yourProp)
