如何设置每个轮播项目的间隔持续时间？

标签： javascript jquery html css twitter-bootstrap

首先，这不是任何帖子的重复，我有自举轮播，我试图为每个引导轮播.item设置间隔，我找到了它的代码from here但是这个例子我的代码片段不起作用我的错误在哪里？我的代码与with this carousel相同，但没有发生任何事情我怎样才能为每个bootstrap轮播项设置间隔？

目前这个每个轮播只能工作，我认为它应该适用于每个幻灯片（默认覆盖）有两个原因：

可以设置第一张幻灯片以显示快速概览等 有些幻灯片可能有更多的文字，需要更长的阅读延迟，有些可能更少...

E.g 

<div class="carousel-inner">
    <div class="active item" data-interval="500">…</div>
    <div class="item" data-interval="5000">…</div>
    <div class="item" data-interval="5000>…</div>
</div>

我的真实例子

＆＃13;
＆＃13; 
$(window).load(function() {
  var t;

  var start = $('#carousel').find('.active').attr('data-interval');
  t = setTimeout("$('#carousel').carousel({interval: 1000});", start - 1000);

  $('#carousel').on('slid.bs.carousel', function() {
    clearTimeout(t);
    var duration = $(this).find('.active').attr('data-interval');

    $('#carousel').carousel('pause');
    t = setTimeout("$('#carousel').carousel();", duration - 1000);
  })
  $('.ani-icon-right-chevron').on('click', function() {
    clearTimeout(t);
  });

  $('.ani-icon-chevron-pointing-to-the-left').on('click', function() {
    clearTimeout(t);
  });

});
＆＃13; 
#carousel {
  width: 700px;
  margin: 70px auto;
}
