自定義引導傳送帶

Question

以下是我的傳送帶代碼的鏈接 https://jsfiddle.net/65jbbp2c/2/ 這裏我希望圖像下面的文本隨各自的幻燈片一起移動。 這裏的問題是文本是「myCarousel」的範圍。

<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

首先你檢查的documentation上引導網站的標題選項（正是@HenryDev發佈）

否則，您可以使用此代碼是否有幫助：

$('#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>

我剛剛將數據添加到包含圖像的項目中，並使用自舉程序中的事件處理程序來管理顯示的當前項目並獲取數據標題值以顯示正確的項目。

此代碼是基本的，但它的工作。

這是一個工作解決方案。希望能幫助到你！

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; 
 
     }
