如何检查最后一项？在版本1中，具有“maximumItem”功能

afterAction: function () {
if (this.currentItem == this.maximumItem) {
}

$(".owl-carousel").on('initialized.owl.carousel changed.owl.carousel refreshed.owl.carousel', function (e) {
    if (!e.namespace) return;
    var carousel = e.relatedTarget,
        current = carousel.current();
    if (current === carousel.maximum()) {
      ...
    }
});
