根據旋轉木馬的哪張幻燈片處於活動狀態顯示隱藏的內容

Question

我想顯示基於哪個輪播項目處於活動狀態的隱藏內容。即使你告訴我如何返回活動類元素ID會幫助很多。

因此到文檔中，你有一些事件來捕獲輪播幻燈片http://getbootstrap.com/javascript/#carousel-events

$('#myCarousel').on('slide.bs.carousel', function() { 
    // do something… 
}) 

你可以把這個事件裏面這下面的腳本...

var liActive = $('#carousel-example-generic').find('ol').find('li.active')[0]; 
 
console.log("li element:", liActive); 
 

 
var slideActive = $(liActive).data('slide-to'); 
 
console.log('data-slide-to active:', slideActive);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel"> 
 
    <!-- Indicators --> 
 
    <ol class="carousel-indicators"> 
 
    <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li> 
 
    <li data-target="#carousel-example-generic" data-slide-to="1"></li> 
 
    <li data-target="#carousel-example-generic" data-slide-to="2"></li> 
 
    </ol> 
 

 
    <!-- Wrapper for slides --> 
 
    <div class="carousel-inner" role="listbox"> 
 
    <div class="item active"> 
 
     <img src="..." alt="..."> 
 
     <div class="carousel-caption"> 
 
     ... 
 
     </div> 
 
    </div> 
 
    <div class="item"> 
 
     <img src="..." alt="..."> 
 
     <div class="carousel-caption"> 
 
     ... 
 
     </div> 
 
    </div> 
 
    ... 
 
    </div> 
 

 
    <!-- Controls --> 
 
    <a class="left carousel-control" href="#carousel-example-generic" 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="#carousel-example-generic" role="button" data-slide="next"> 
 
    <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span> 
 
    <span class="sr-only">Next</span> 
 
    </a> 
 
</div>
