我正在使用引导jquery旋转木马幻灯片内容。我在旋转木马下面也有一些内容。此内容应隐藏/显示幻灯片所显示的内容。

由于引导程序在当前幻灯片上使用active，所以我编写了下面的代码。现在，当我使用箭头的时候，这个方法就起作用了。但是，如果我使用键盘箭头显示下一个和上一个，或者当幻灯片是自动播放时，内容就不会相应地显示/隐藏。

jQuery：

    $('#success-stories .carousel-control.left, #success-stories .carousel-control.right').click(function() {
        if ( $('#success-stories .item1').hasClass("active") ) {
            $('.success1').removeClass("active"); 
            $('.success2').addClass("active"); 
        }
        if ( $('#success-stories .item2').hasClass("active") ) {
            $('.success2').removeClass("active"); 
            $('.success1').addClass("active"); 
        }

    });

谢谢

要实现这一点，有很多种方法。根据您正在运行的引导程序的版本，可以使用slid、slide或slide.bs.carousel。

3之前的引导版本

您可以尝试这一点(取决于您正在运行的引导程序的哪个版本)，使用slid函数，它可以检测幻灯片事件何时完成：

$("#myCarousel").carousel()
 $("#myCarousel").bind("slid", function(){
    $currentActive = $("#myCarousel .active").attr('id');
       if($currentActive == "item1"){
           //then show something
       }else if(...){....}
  })

使用幻灯片和幻灯片事件，您可以找到当前幻灯片和下一个幻灯片/目标幻灯片，这个解决方案还没有经过测试，但应该可以正常工作。

$('.carousel').on('slide',function(e){
    var slideFrom = $(this).find('.active').index();
    var slideTo = $(e.relatedTarget).index();
    if(slideTo == 1){
       //do something for item one, realise here i am working with indexes
    }
});

在自助3中：

$('#myCarousel').on('slide.bs.carousel', function (e) {
  //according to the documentation this event is fired when the slide method is invoked

    var slideFrom = $(this).find('.active').index();
    var slideTo = $(e.relatedTarget).index();
    if(slideTo == 1){
       //do something for item one, realise here i am working with indexes
    }
})

为什么不给出成功内容的子类div ids，而不是使用类来标识它们，而是使用它们的单个ids。

例如：

 <div id="success-content">
                <div class="success1 active" id="successOne">
                    <h4 class="rounded-heading">Eleanor's Story</h4>
                    <p>
                        <span class="quote-start"></span>
                             Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. comes from a line in section 1.10.32.
                        <span class="quote-finish"></span>
                    </p>
