仅当在ASP.NET MVC中可见字段时，才需要进行字段验证

问题描述

我有一个复选框，您可以在其中隐藏/显示日期选择器字段.

I have a checkbox where you can hide/show a datepicker field.

但是当datepicker字段隐藏时，不必进行验证.

But when the datepicker field is hidden there has to be no validation.

这是复选框:

  @Html.CheckBox("showEindDatum", (Request.Form["showEindDatum"] ?? string.Empty).Contains("true"))

这是日期选择器:

   @FormGroupHelper.CreateFormGroup(Html, m => m.EindDatum, Html.Kendo().DatePickerFor(m => m.EindDatum).Min(Model.EindDatum.HasValue ? Model.EindDatum.Value : DateTime.Today).Format("dd-MM-yyyy").ParseFormats(new string[] { "ddMMyyyy" }))

此字段的属性如下所示:

The properties of this fields are looking like this:

 [Display(Name = "Einddatum wijziging")]
        [Required(ErrorMessageResourceType = typeof(Messages), ErrorMessageResourceName = "Global_Validatie_VeldVerplicht")]
        public DateTime? EindDatum { get; set; }

 public bool showEindDatum { get; set; }

这是它的jQuery:

And this is the jquery of it:

if ($('#showEindDatum').prop('checked')) {

            $(".EinddatumDatepicker").show();
            $("#meldingEindDatumCheck").show();

        }
        else {
            $(".EinddatumDatepicker").hide();
            $("#meldingEindDatumCheck").hide();
        }

        $("#showEindDatum").on("click", function ()
        {
            $(".EinddatumDatepicker").toggle(this.checked);
            $("#meldingEindDatumCheck").toggle(this.checked);

        });

那么我必须更改的是，隐藏了datepicker字段时没有验证?

So what I have to change that there is no validation when the datepicker field is hidden?

谢谢

所以你的意思是

 $.validator.setDefaults({ ignore: null });

        if ($('#showEindDatum').prop('checked')) {

            $(".EinddatumDatepicker").show();
            $("#meldingEindDatumCheck").show();
            $("#geenEinddatumIngevuld").hide();

        }
        else {
            $(".EinddatumDatepicker").hide();
            $("#meldingEindDatumCheck").hide();
            $("#geenEinddatumIngevuld").show();

        }

        $("#showEindDatum").on("click", function () {
            $(".EinddatumDatepicker").toggle(this.checked);
            $("#meldingEindDatumCheck").toggle(this.checked);
            $("#geenEinddatumIngevuld").toggle(this.checked);

        });

这不起作用.

但是表单还具有post方法，例如:

But the form has also a post method, like this:

using (Html.BeginForm("Formulier", "PersoneelsDossier", FormMethod.Post, new { @id = "PDForm", name = "PDForm" }))
}

您的意思是这样的:

 $(document).ready(function () {

        //$("#PDForm").data("validator").settings.ignore = ".ignore, :hidden";

        if ($('#showEindDatum').prop('checked')) {

            $(".EinddatumDatepicker").show();
            $("#meldingEindDatumCheck").show();
            $("#geenEinddatumIngevuld").hide();

        }
        else {
            $(".EinddatumDatepicker").hide();
            $("#meldingEindDatumCheck").hide();
            $("#geenEinddatumIngevuld").show();

        }

        $("#showEindDatum").on("click", function () {
            $(".EinddatumDatepicker").toggle(this.checked);
            $("#meldingEindDatumCheck").toggle(this.checked);
            $("#geenEinddatumIngevuld").toggle(this.checked);

        });

        $.validator.setDefaults({ ignore: null });

 });

您的意思是这样的:

$.validator.setDefaults({ ignore: null });

        if ($('#showEindDatum').prop('checked')) {

            $(".EinddatumDatepicker").show();
            $("#meldingEindDatumCheck").show();
            $("#geenEinddatumIngevuld").hide();

        }
        else {
            $(".EinddatumDatepicker").hide();
            $("#meldingEindDatumCheck").hide();
            $("#geenEinddatumIngevuld").show();

        }

        $("#showEindDatum").on("click", function () {
            $(".EinddatumDatepicker").toggle(this.checked);
            $("#meldingEindDatumCheck").toggle(this.checked);
            $("#geenEinddatumIngevuld").toggle(this.checked);

        });

不起作用

推荐答案

默认情况下，jQuery validate会忽略隐藏字段，宽度和高度为零的元素，具有CSS display:none的元素以及具有不可见父元素的任何元素(使用相同条件)

By default jQuery validate ignores hidden fields, elements with zero width and height, those with css display:none and any elements with an invisible parent (using same criteria).

不过，可以通过添加以下脚本来覆盖忽略设置

The ignore setting can however be overridden by adding the following script

// By default validator ignores hidden fields.
// change the setting here to ignore nothing
$.validator.setDefaults({ ignore: null });
