javascript - Animate Bootstrap轮播字幕和按钮

在轮播中，要为字幕和按钮制作动画，下面是从this jsfiddle复制的代码，但是在我的jsfiddle中，动画不起作用，并且实际幻灯片也未显示。

的HTML


   
   
        
    
    
  

<!-- Wrapper for slides -->
 <div class="carousel-inner">
<div class="item active">
  <img src="http://placehold.it/1200x400" alt="...">
  <div class="carousel-caption">
      <h3 class="toggleHeading">Caption Text</h3>
      <p class="toggleCaption">This is some text<p>
  </div>
</div>
  <div class="item">
  <img src="http://placehold.it/1200x400" alt="...">
  <div class="carousel-caption">
      <h3 class="toggleHeading">Caption Text 2</h3>
       <p class="toggleCaption">This is some text<p>
  </div>
  </div>
     <div class="item">
   <img src="http://placehold.it/1200x400" alt="...">
  <div class="carousel-caption">
      <h3 class="toggleHeading">Caption Text 3</h3>
       <p class="toggleCaption">This is some text<p>
  </div>
</div>
</div>

 <!-- Controls -->
 <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
  <span class="glyphicon glyphicon-chevron-left"></span>
</a>
 <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
  <span class="glyphicon glyphicon-chevron-right"></span>
</a>
</div> <!-- Carousel -->

JS

  var carouselContainer = $('.carousel');
   var slideInterval = 5000;

function toggleH(){
    $('.toggleHeading').hide()
    var caption = carouselContainer.find('.active').find('.toggleHeading').addClass('animated fadeInRight').one('webkitAnimationEnd mozAnimationEnd MSAnimationEnd oanimationend animationend',
        function (){
        $(this).removeClass('animated fadeInRight')});
caption.slideToggle();
}

function toggleC(){
    $('.toggleCaption').hide()
    var caption = carouselContainer.find('.active').find('.toggleCaption').addClass('animated fadeInUp').one('webkitAnimationEnd mozAnimationEnd MSAnimationEnd oanimationend animationend',
        function (){
        $(this).removeClass('animated fadeInUp')
});
caption.slideToggle();
}
  carouselContainer.carousel({
  interval: slideInterval, cycle: true, pause: "hover"})
 .on('slide.bs.carousel slid.bs.carousel', toggleH).trigger('slide.bs.carousel')
 .on('slide.bs.carousel slid.bs.carousel', toggleC).trigger('slide.bs.carousel');

的CSS

 .toggleHeading {
animation-delay: 0.5s;
 -webkit-animation-delay: 0.5s;
 -moz-animation-delay: 0.5s;
   -o-animation-delay: 0.5s;
   -moz-transition: none !important;
}

 .toggleCaption {
animation-delay: 1.5s;
 -webkit-animation-delay: 1.5s;
 -moz-animation-delay: 1.5s;
   -o-animation-delay: 1.5s;
   -moz-transition: none !important;
 }

Please check this fiddle with my code，因此无法正常工作。

最佳答案

延迟更新

调整HTML，并将标题和按钮移动到自己的div中，以便CSS适当地应用延迟动画。

HTML：

 <!-- Header Carousel -->
<header id="myCarousel" class="carousel slide">
    <!-- Indicators -->
    <ol class="carousel-indicators">
        <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
        <li data-target="#myCarousel" data-slide-to="1"></li>
        <li data-target="#myCarousel" data-slide-to="2"></li>
    </ol>
    <!-- Wrapper for slides -->
    <div class="carousel-inner">
        <div class="item active">
            <img src="http://placehold.it/1200x400" alt="...">
            <div class="carousel-caption">
                <div class="toggleCaption">
                     <h3>Caption Text</h3>
                </div>
                <div class="toggleButton">
                    <p><a class="btn btn-default-outline btn-lg" role="button">Shop Now</a>
                    </p>
                </div>
            </div>
        </div>
        <div class="item">
            <img src="http://placehold.it/1200x400" alt="...">
            <div class="carousel-caption">
                <div class="toggleCaption">

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

CSS：

.toggleCaption {
