javascript - 动画标题 Bootstrap 3 轮播

Question

我正在寻找一种为 Bootstrap 3 旋转木马的标题制作动画的好方法。我找到了这篇文章Bootstrap carousel-caption animation .

遗憾的是它不起作用，因为它在 fiddle 中工作。在我的页面上，动画并不是真正的动画。标题突然出现并且没有飞入。此外，动画每张图片只能工作一次。因此，在轮播的第二轮中，字幕不再显示。

我的 CSS 是:

.carousel-caption {
    z-index: 0;
    font-size:24px;
    right: 0;
    bottom: 0;
    left: 0;
    top: 0;
    padding-bottom: 30px;
    padding-top:25%;
    height: 100% !important;
    background:rgba(0, 0, 0, 0.25);   
    display: none;
}

我的JS:

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

    function toggleCaption() {
        $('.carousel-caption').hide();
        var caption = carouselContainer.find('.active').find('.carousel-caption');
        caption.delay(500).toggle("slide", {direction:'right'});
    }


    carouselContainer.carousel({
        interval: slideInterval,
        cycle: true,
        pause: "hover"
    }).on('slid.bs.carousel', function() {
        toggleCaption();
    });

我遇到了同样的问题，终于找到了解决方案!

我只是 Jquery 的新手，所以我相信您可以解决这个问题。此外，可能最好使用您自己的 Carousal Structure，并且只使用 2 个类来制作您想要动画的字幕。

诀窍是使用 Animate.css，但您必须在动画字幕上禁用 Firefox 的 Ease 功能，否则会导致问题。

HTML:

    <div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
      <!-- Indicators -->
      <ol class="carousel-indicators">
        <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
        <li data-target="#carousel-example-generic" data-slide-to="1"></li>
        <li data-target="#carousel-example-generic" 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">
              <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 class="item">

               <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:

    <script>
    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');
     </script>

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;
    }
