推荐答案

仅当将类应用于div时，动画才应用一次.因此，所有幻灯片仅在开始时动画一次，但是您只能看到第一个div，因此没有其他反应.

The animation is only applied once when the class is applied to a div. Therefore all of your slides animate once at the start only, but you can only see the first div, and so nothing else happens.

如果您观察轮播中的幻灯片变化，然后从所有div移除动画反弹"类，然后立即将其重新应用于屏幕上的那个，那么您可以看到每个动画.

If you watch for slide changes in the carousel and then remove the 'animate bounce' classes from all divs before instantly re-applying it to the one on screen then you can see each one animate.

尝试这个jquery:

Try this jquery:

$(document).ready(function() {
  var owl = $('.owl-carousel');

  owl.owlCarousel({
    items: 1,
    loop: true,
    autoplay: true,
    autoplayTimeout: 3500,
    nav: true,
    margin: 10,
  });

  owl.on('changed.owl.carousel', function(event) {
      var item = event.item.index - 2;     // Position of the current item
      $('h1').removeClass('animated bounce');
 $('.owl-item').not('.cloned').eq(item).find('h1').addClass('animated bounce');
  });

});

，然后在您的html中仅对第一张幻灯片使用动画反弹"类(将其从其他幻灯片中删除):

and then in your html only use the 'animate bounce' classes for the first slide (remove it from the others):

<div id='monitor'>

</div>
<div class="owl-carousel owl-theme">

  <div class="item"><img src="http://placehold.it/200x200">
    <div class="caption">
      <h1 class="animated bounce">First Caption</h1></div>
  </div>

  <div class="item"><img src="http://placehold.it/200x200">
    <div class="caption">
      <h1 class="">Second Caption</h1></div>
  </div>

  <div class="item"><img src="http://placehold.it/200x200">
    <div class="caption">
      <h1 class="">Third Caption</h1></div>
  </div>

  <div class="item"><img src="http://placehold.it/200x200">
    <div class="caption">
      <h1 class="">Fourth Caption</h1></div>
  </div>

</div>
<!-- End Carousel -->
