jQuery Boostrap Carousel根据当前幻灯片显示内容 [英] jQuery Boostrap Carousel Show content according to current slide

问题描述

我正在使用引导jquery轮播来滑动内容.在轮播下，我也有一些内容.该内容应根据所显示的幻灯片进行隐藏/显示.

I am using bootstrap jquery carousel to slide content. I also have some content below the carousel. This content should hide/show according to which slide is showing.

由于引导程序在当前幻灯片上处于活动状态，因此我在下面编写了代码. 现在，当我使用箭头时，此方法有效.但是，如果我使用键盘箭头作为下一个和上一个箭头，或者当幻灯片自动播放时，内容将不会相应地显示/隐藏.

Since bootstrap uses active on the current slide I wrote the code below. Now this works when I use the arrows. But if I use keyboard arrows for next and previous, or when the slide is autoplay, the content does not show/hide accordingly.

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

推荐答案

有很多方法可以实现此目的.根据运行的引导程序版本，可以使用slid，slide或slide.bs.carousel.

There are tons of ways to implement this. Depending on what version of bootstrap you are running, you can use the slid, slide or slide.bs.carousel.

您可以尝试此操作(取决于您正在运行的引导程序的版本)，使用slid函数，它可以检测到slide事件何时完成:

You can try this (depending on what version of bootstrap you are running), with the slid function, it detects when the slide event is completed:

$("#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slid事件，您可以找到当前幻灯片和下一张幻灯片/目标幻灯片，该解决方案尚未经过测试，但应该可以正常工作.

using the slide and the slid event you can find current slide and the next slide/target slide, this solution hasn't been tested yet but it should work fine.

$('.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
    }
});

在引导程序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
    }
})

为什么不给成功成功的孩子分配div ID，而是使用他们的单个ID而不是使用类来标识它们.
例如:

Update

Why not give your success-content children div ids and instead of using the class to identify them, you use their individual ids.
for example:

 <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.

                </div><!-- end success1 -->
                <div class="success2" id="successTwo">
                    <h4 class="rounded-heading">Melsor's Story</h4>
