为什么这个 Bootstrap Carousel 滑动功能对我不起作用？

Question

我找到了这个代码笔：https://codepen.io/andrearufo/pen/rVWpyE

我很想使用它，但由于某种原因，它对我不起作用，即使我复制它而不改变任何东西。这是为什么呢？

我没有忘记嵌入 bootstrap 或 jquery。

我还尝试了其他滑动功能的解决方案，但由于某种原因，它们都不起作用。滑动工作的唯一轮播（我在 Google Chrome 开发人员工具中尝试过）是在这个 codepen 上。

$(".carousel").swipe({

  swipe: function(event, direction, distance, duration, fingerCount, fingerData) {

    if (direction == 'left') $(this).carousel('next');
    if (direction == 'right') $(this).carousel('prev');

  },
  allowPageScroll:"vertical"

});

这是您可能会错过的示例 JQuery 或 Swipe LIB。

$(".carousel").swipe({

  swipe: function(event, direction, distance, duration, fingerCount, fingerData) {

    if (direction == 'left') $(this).carousel('next');
    if (direction == 'right') $(this).carousel('prev');

  },
  allowPageScroll:"vertical"

});

希望你能得到帮助

(function ($) {
    var touchStartX = null;

    $('.carousel').each(function () {
        var $carousel = $(this);
        $(this).on('touchstart', function (event) {
            var e = event.originalEvent;
            if (e.touches.length == 1) {
                var touch = e.touches[0];
                touchStartX = touch.pageX;
            }
        }).on('touchmove', function (event) {
            var e = event.originalEvent;
            if (touchStartX != null) {
                var touchCurrentX = e.changedTouches[0].pageX;
                if ((touchCurrentX - touchStartX) > 60) {
                    touchStartX = null;
                    $carousel.carousel('prev');
                } else if ((touchStartX - touchCurrentX) > 60) {
                    touchStartX = null;
                    $carousel.carousel('next');
                }
            }
        }).on('touchend', function () {
            touchStartX = null;
        });
    });

})(jQuery);
