Например как мне получить значение ключа matched в 15 строке?

function closeModal() { 
    $('.modal-window, .modal-overlay').removeClass('active');
    $('body').css('overflow-y', 'auto');
}
$('.modal-close').click(function (e) {
     e.preventDefault();
     closeModal();
});

$(this).keydown(function (eventObject) {
     if (eventObject.which == 27) {
         closeModal();
     }
});
