javascript - 如何在 Bootstrap Popover 中启用 Bootstrap 4 Carousel

Question

我正在做这个演示，并且很想知道为什么控制按钮在 Bootstrap Popover 内的 Bootstrap 4 Carousel 上不起作用。如您所见，轮播正在运行，正如我已经添加的那样

$("[data-toggle=popover]").on('shown.bs.popover', function () {
   $('.carousel-inner').carousel();
});

但控件不起作用：

$("[data-toggle=popover]").each(function(i, obj) {
  $(this).popover({
    html: true,
    content: function() {
      var id = $(this).attr('id')
      return $('#popover-content-' + id).html();
    }
  });

});

$("[data-toggle=popover]").on('shown.bs.popover', function() {
  $('.carousel-inner').carousel();
});

.carousel-inner img {
  width: 100%;
  height: 100%;
}
