Question

在Bootstrap 3中，使用jQuery有一种方法可以按照我的轮播索引进行排序并添加每张幻灯片的自定义间隔，这样我就可以有一张幻灯片10000毫秒和另一张500毫秒等？

我知道您可以设置数据间隔属性，但这会设置所有幻灯片的速度，因为您无法为每个项目添加自定义时间间隔属性。

data-interval="3000"

我的旋转木马设置如下：

<div id="carousel" class="carousel slide">

     <div class="carousel-inner">

    <div class="item active">
        <a href="#">
              <img class="img-responsive" src="">
        </a>
    </div>

    <div class="item">
        <a href="#">
             <img class="img-responsive" src="">
        </a>
    </div>

    <div class="item">
        <a href="#">
             <img class="img-responsive" src="">
        </a>
    </div>

    <div class="item">
        <a href="#" >
            <img class="img-responsive" src="">
        </a>
    </div>
</div>

您可以创建一个自定义属性，表示幻灯片应该显示多长时间，将其拉出slide.bs.carousel或slid.bs.carousel事件中的有效项目（根据您的喜好/最适合您的情况）），然后将其设置为超时以转到下一张幻灯片。

$('#carousel-example-generic').on('slide.bs.carousel', function() {
  var interval = $('div.item.active').attr('duration');
  setTimeout(function() {
    $('.carousel').carousel('next');
  }, interval);
});

    <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>
    <li data-target="#carousel-example-generic" data-slide-to="3"></li>
  </ol>

  <!-- Wrapper for slides -->
  <div class="carousel-inner" role="listbox">
    <div class="item active" duration="3000">

      <div class="carousel-caption">
        First
      </div>
    </div>
    <div class="item" duration="2000">
      <img src="http://placehold.it/400x200" alt="..." />
      <div class="carousel-caption">
        Second

    </div>
    <div class="item" duration="1000">
      <img src="http://placehold.it/400x200" alt="..." />
      <div class="carousel-caption">
        Third
      </div>
    </div>
    <div class="item" duration="500">
      <img src="http://placehold.it/400x200" alt="..." />

    <span class="sr-only">Previous</span>
  </a>
  <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>

@MattD给出的解决方案似乎运行良好，或者您可以使用以下代码覆盖carousel插件bu的滑动功能：

<script src="js/carousel.js"></script>
<script>
  $.fn.carousel.Constructor.prototype.cycle = function (e) {

    e || (this.paused = false)
    this.interval && clearInterval(this.interval)

    this.options.interval
      && !this.paused
      && (this.interval = setInterval($.proxy(this.next, this), this.$element.find('.item.active').data('interval') || this.options.interval))

    return this
  }
</script>

以上功能可让您设置利用data-interval属性的每张幻灯片的时间间隔，如下所示：

<div class="item" data-interval="500">
