自定义引导传送带

Question

以下是我的传送带代码的链接 https://jsfiddle.net/65jbbp2c/2/ 这里我希望图像下面的文本随各自的幻灯片一起移动。 这里的问题是文本是“myCarousel”的范围。

<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 class="item"> 
     <img src="https://dncache-mauganscorp.netdna-ssl.com/thumbseg/1404/1404088-bigthumbnail.jpg" alt="Chania" width="400" height="200"> 
     </div> 

     <div class="item"> 
     <img src="https://static.pexels.com/photos/55813/geranium-wave-water-rings-55813.jpeg" alt="Flower" width="400" height="200"> 
     </div> 

     <div class="item"> 
     <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"> 
    side2 text 
    </div> 
    <div class="side3"> 
    side3 text 
    </div> 
    <div class="side4"> 
    side4 text 
    </div> 
    </div> 
</div> 

Answer 1

首先你检查的documentation上引导网站的标题选项（正是@HenryDev发布）

否则，您可以使用此代码是否有帮助：

$('#myCarousel').on('slide.bs.carousel', function (e) { 
 
\t // 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"> 
 
    \t <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，并使用自举程序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，但它的工作。

这是一个工作解决方案。希望能帮助到你！

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; 
 
     }
