Question

我有一个checkBoxFor用于JQuery表单并绑定到我的模型，我的问题是，当用户检查或取消选中该框时，用于某些客户端验证的值始终为true，并且用于服务器端的值验证总是错误的。为什么我的复选框没有更新值？

查看：

 <form id="companyForm">
    <fieldset>
        <p>
            @Html.LabelFor(model => model.allCompany, new { @checked = "checked" })
            @Html.CheckBoxFor(model => model.allCompany)
        </p>
        <p>
            @Html.LabelFor(model => model.hierarchyValidation)
            @Html.DisplayFor(model => model.hierarchyValidation)
            @Html.HiddenFor(model => model.hierarchyValidation)
            @Html.ValidationMessageFor(model => model.hierarchyValidation)
        </p>
        <!-- Allow form submission with keyboard without duplicating the dialog button -->
        <input type="submit" tabindex="-1" style="position:absolute; top:-1000px">
    </fieldset>
</form>

查看模型

公共类AXAddRoleViewModel {

    public bool allCompany { get; set; }

    [Display(Name = "HierarchySelectList")]
    [IsEmptyAttribute("hierarchyValidation", "allCompany")]
    public string hierarchyValidation { get; set; }
}

客户端验证：

var isApplicationValid = $('#application').valid();
var isHierarchyValid = $('#hierarchyValidation').valid();

if (isHierarchyValid && isCompanyValid) {
    var roleName = $("#roleName").val();
    var hierarchy = $("#hierarchyValidation").val().toString();

    var data = {
        "reasons": message,
        "hierarchyValidation": hierarchy
    };

    $.ajax({
        url: url,
        type: "POST",
        data: data,
        success: function (data, textStatus, jqXHR) {
            alert("Success");
        },
            error: function (jqXHR, textStatus, errorThrown) {
                alert("Error");
            }
        });
    }
}

自定义验证器属性：

public enum Comparison
{
    IsEmpty,
    ContainsValue
}

[AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = true)]
public sealed class IsEmptyAttribute : ValidationAttribute, IClientValidatable
{
    private const string DefaultErrorMessage = "{0} Is required if a value from {1} is not selected.";

    public string ValueLabel { get; private set; }
    public string CompaniesValue { get; set; }

    public IsEmptyAttribute(string valueLabel, string companiesValue)
        : base(DefaultErrorMessage)
    {
        if (string.IsNullOrEmpty(valueLabel))
        {
            throw new ArgumentNullException("otherProperty");
        }
        ValueLabel = valueLabel;
        CompaniesValue = companiesValue;
    }

    public override string FormatErrorMessage(string name)
    {
        return string.Format(ErrorMessageString, ValueLabel, CompaniesValue);
    }

    protected override ValidationResult IsValid(object value,
                          ValidationContext validationContext)
    {
        var allCompaniesSelected = validationContext.ObjectInstance.GetType()
                                   .GetProperty(CompaniesValue);
        var allCompaniesSelectedValue = allCompaniesSelected
                              .GetValue(validationContext.ObjectInstance, null);

        if (Convert.ToBoolean(allCompaniesSelectedValue) == false)
        {
            if (value == null)
            {

                return new ValidationResult(
                    FormatErrorMessage(validationContext.DisplayName));
            }
        }
        return ValidationResult.Success;
    }

    public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
    {
        var clientValidationRule = new ModelClientValidationRule()
        {
            ErrorMessage = FormatErrorMessage(metadata.GetDisplayName()),
            ValidationType = "isempty"
        };

        clientValidationRule.ValidationParameters.Add("companiesvalue", CompaniesValue);

        return new[] { clientValidationRule };
    }
}

自定义验证器javascript：

(function ($) {
    $.validator.addMethod("isempty", function (value, element, params) {
        if (this.optional(element)) {
            var allCompanies = $('#addRoleCompany_allCompany')
            if (allCompanies.val() == false) {
                var otherProp = $('#addRoleCompany_' + params)
                return (otherProp.val() != value);
            }
        }
        return true;
    });
    $.validator.unobtrusive.adapters.addSingleVal("isempty", "otherproperty");

}(jQuery));

有人能告诉我在哪里可以找到问题以及问题是什么？

感谢您对此问题的任何帮助。

事实证明，我忽略了这样一个事实，即我需要在检查框是否勾选后从Jquery传递值。

一个简单的错误。谢谢大家帮我解决这个问题。

当用户勾选该框时，CheckBoxFor值不会更改
