Why won't this Bootstrap Carousel swipe function work for me?

Question

I found this codepen: https://codepen.io/andrearufo/pen/rVWpyE

and I'd love to use it, but for some reason it won't work for me, even if I copy it without changing a single thing. Why is this?

I haven't forgotten to embed bootstrap nor jquery.

I've also tried other solutions for a swipe function, but for some reason none of them worked. The only carousel where the swipe worked (I've tried in Google Chrome developer tools) was on this codepen.

$(".carousel").swipe({

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

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

  },
  allowPageScroll:"vertical"

});

Here is the example you might miss JQuery or 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"

});

Answer 2

I hope you will got help with this

(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);
