自定义轮播间隔？

在Bootstrap 3中，使用jQuery有一种方法可以按轮播的索引进行排序，并为每张幻灯片添加自定义间隔，以便我可以一张幻灯片10000ms，另一张500ms等？

我知道您可以设置data-interval属性，但这可以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的interval属性。

data-interval="3000"

我的轮播设置如下：

<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，该属性表示应显示幻灯片多长时间，将其拉出以显示slide.bs.carousel或slid.bs.carousel事件中的活动项（无论您偏爱/最适合自己的行为），然后将其设置为超时以转到下一个滑动。

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