如何在Bootstrap Popover内部启用Bootstrap 4 Carousel

Question

您能否看一下这个演示，让我知道为什么Bootstrap Popover内部的Bootstrap 4 Carousel上的控制按钮不起作用？如您所见，旋转木马正在按我已经添加的方式工作

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

但是控件不起作用

$("[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%;
}
