Question

我有一个淘汰复选框，当它被检查时，它被发布为false。任何帮助，将不胜感激视图：

<div class="managers" data-bind="foreach: managers">
    <div class="row">
        <div class="col-sm-12">
            <div class="checkbox col-xs-12" data-bind="visible: isVerified == false && postalMessage != '' && postalMessage != null">
                <label>
                    <input type="checkbox" data-bind="attr: { checked: isCorrect, name: 'Personnels[' + $index() + '].IsCorrect' }"> <b>@AddressResource.IsCorrect</b>
                </label>
        </div>
    </div>
</div> <!-- .row -->

使用Javascript：

function Personnel(personnelId, firstName, middleName, lastName, primaryPhone, primaryPhoneExtension, secondaryPhone, secondaryPhoneExtension, fax, faxExtension, primaryEmail, secondaryEmail, postalAddress, city, state, zip, isVerified, isCorrect, postalMessage) {
        var self = this;
        self.personnelId = personnelId;
        self.firstName = firstName;
        self.middleName = middleName;
        self.lastName = lastName;
        self.primaryPhone = primaryPhone;
        self.primaryPhoneExtension = primaryPhoneExtension;
        self.secondaryPhone = secondaryPhone;
        self.secondaryPhoneExtension = secondaryPhoneExtension;
        self.fax = fax;
        self.faxExtension = faxExtension;
        self.primaryEmail = primaryEmail;
        self.secondaryEmail = secondaryEmail;
        self.postalAddress = postalAddress;
        self.city = city;
        self.state = state;
        self.zip = zip;
        self.isVerified = isVerified;
        self.isCorrect = ko.observable(isCorrect);
        self.postalMessage = postalMessage;
    }

    function KOViewModel() {
        var self = this;

        self.states = ko.observableArray();

        var modelStates = mStates;

        for (var i = 0; i < modelStates.length; i++) {
            var state = modelStates[i];

            self.states.push({
                id: state.Value,
                state: state.Text
            });
        }

        self.managers = ko.observableArray();
        var modelManagers = mManagers;

        if (modelManagers.length === 0) {
            self.managers.push(new Personnel(0, "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", ""));
        } else {
            for (var x = 0; x < modelManagers.length; x++) {
                var personnel = modelManagers[x];
                self.managers.push(new Personnel(personnel.PersonnelId, personnel.FirstName, personnel.MiddleName, personnel.LastName, personnel.PrimaryPhone, personnel.PrimaryPhoneExtension, personnel.SecondaryPhone, personnel.SecondaryPhoneExtension, personnel.Fax, personnel.FaxExtension, personnel.PrimaryEmail, personnel.SecondaryEmail, personnel.PostalAddress, personnel.City, personnel.State, personnel.Zip5, personnel.IsVerified, personnel.IsCorrect, personnel.PostalMessage));
            }
        }

        self.addPersonnel = function () {
            self.managers.push(new Personnel(0, "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", ""));
        };
    }

您实际上并未使用敲除检查的绑定。您正在使用带有'checked'属性的attr绑定，该属性可能没有所有正确的事件挂钩。您只需将attr绑定参数之外的已检查部分移动到其自己的绑定。

data-bind="attr: { checked: isCorrect, ...
//becomes
data-bind="checked: isCorrect, attr: { ...

Knockout复选框始终为false
