Question

以下是我的轮播代码的链接 https://jsfiddle.net/65jbbp2c/2/ 在这里，我希望图像下方的文本与相应的幻灯片一起移动。这里的问题是文本在外面＆＃34; myCarousel＆＃34;范围。

<div class="container">
  <div id="myCarousel" class="carousel slide" data-ride="carousel" data-interval="3000">
    <!-- 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>
      <li data-target="#myCarousel" data-slide-to="3"></li>
    </ol>

    <!-- Wrapper for slides -->
    <div class="carousel-inner text-center" role="listbox">
      <div class="item active">
        <img src="https://static.pexels.com/photos/36762/scarlet-honeyeater-bird-red-feathers.jpg" alt="Chania" width="400" height="200">

      </div>
    </div>

    <!-- Left and right controls -->
    <a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
      <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>

  </div>

  <div id="slideCapstion" class="text-center">
    <div class="side1">

  <div class="side2">

这是一个有效的解决方案。希望它有所帮助！

    jQuery(function ($) {
        $('.carousel').carousel();
        var caption = $('div.item:nth-child(1) .carousel-caption');
        $('.information').html(caption.html());
        caption.css('display', 'none');

        $(".carousel").on('slide.bs.carousel', function (evt) {
            var caption = $('div.item:nth-child(' + ($(evt.relatedTarget).index() + 1) + ') .carousel-caption');
            $('.information').html(caption.html());
            caption.css('display', 'none');
        });
    });

 .container, .information {
            width: 600px;
            margin: auto;
            color: #000;
        }

        .carousel-caption {
            color: #000;

首先，您是否在documentation检查了bootstrap网站上的标题选项（正是@HenryDev发布的内容）

否则，如果有帮助，您可以使用此代码：

$('#myCarousel').on('slide.bs.carousel', function (e) {
	// Hide all caption
   $('div#slideCapstion div').addClass('hidden');
   // Show the specific caption associated to the image
  $('div#slideCapstion div.' + e.relatedTarget.dataset.caption).removeClass('hidden');
})

<div class="container">
  <div id="myCarousel" class="carousel slide" data-ride="carousel" data-interval="3000">
    <!-- 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>
      <li data-target="#myCarousel" data-slide-to="3"></li>
    </ol>

    <!-- Wrapper for slides -->
    <div class="carousel-inner text-center" role="listbox">
      <div class="item active" data-caption="side1">
        <img src="https://static.pexels.com/photos/36762/scarlet-honeyeater-bird-red-feathers.jpg" alt="Chania" width="400" height="200">
      </div>

      <div class="item" data-caption="side2">
        <img src="https://dncache-mauganscorp.netdna-ssl.com/thumbseg/1404/1404088-bigthumbnail.jpg" alt="Chania" width="400" height="200">
      </div>
    
      <div class="item" data-caption="side3">
        <img src="https://static.pexels.com/photos/55813/geranium-wave-water-rings-55813.jpeg" alt="Flower" width="400" height="200">
      </div>

      <div class="item" data-caption="side4">
        <img src="http://tsikave.ostriv.in.ua/images/publications/4/15434/1364988835.jpg" alt="Flower" width="400" height="200">
      </div>
    </div>

    <!-- Left and right controls -->
    <a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
      <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
      <span class="sr-only">Previous</span>
    </a>
    <a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
      <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
      <span class="sr-only">Next</span>
    </a>
  </div>
  
  <div id="slideCapstion" class="text-center">
  	<div class="side1">
  side1 text
  </div>
  <div class="side2 hidden">
  side2 text
  </div>
  <div class="side3 hidden">
  side3 text
  </div>
  <div class="side4 hidden">
  side4 text
  </div>
  </div>
</div>

我刚刚将数据添加到包含图像的项目中，并使用bootstrap中的事件处理程序来管理显示的当前项目，并获取数据标题值以显示正确的项目。

此代码是基本的，但它可以完成任务。
