单击“是”后单击“否”时，是否可以隐藏“请指定...”字段？

$(document).ready(function() {
        var policeInvolvedYes = $('input[name="policeInvolved"][value="yes"]');
        var policeDetailsGroup = $('#policeDetailsGroup');
        var policeDetails = $('#policeDetails');

        function updatePoliceDetailsField() {
            if (policeInvolvedYes.is(':checked')) {
                policeDetailsGroup.show();
                policeDetails.prop('required', true);
            } else {
                policeDetailsGroup.hide();
                policeDetails.prop('required', false);
            }
        }

        policeInvolvedYes.on('change', updatePoliceDetailsField);
        updatePoliceDetailsField();
    });
