Question

我试图制作一个轮播，其中包含多个连续的图像，并且每次仅使用引导程序一次滑动一个图像。像这样：

我尝试遵循此post。我使用的是 bootstrap-3.3.6和jquery-2.2.2 ，而不是 bootstrap-4.3.1和jquery-3.3.1 ，但在我的情况下，图像位于垂直订单，而不是水平订单。我究竟做错了什么？如何按水平顺序排列图像？

$(document).ready(function () {
  $('.fdi-Carousel .carousel-item').each(function () {
    var next = $(this).next();
    if (!next.length) {
      next = $(this).siblings(':first');
    }
    next.children(':first-child').clone().appendTo($(this));

    if (next.next().length > 0) {
      next.next().children(':first-child').clone().appendTo($(this));
    }
    else {
      $(this).siblings(':first').children(':first-child').clone().appendTo($(this));
    }
  });
});

#outerCarousel {
  width: 100%;
}
.carousel-control-prev-icon,
.carousel-control-next-icon {
  background-color: tomato !important;
}
.carousel-inner.onebyone-carousel {
  margin: auto;
  width: 90%;
}
.onebyone-carousel .active.carousel-item-left {
  left: -33.33%;
}
.onebyone-carousel .active.carousel-item-right {
  left: 33.33%;
}
.onebyone-carousel .carousel-item-next {
  left: 33.33%;
}
.onebyone-carousel .carousel-item-prev {
  left: -33.33%;
}

首先，您提供的代码有很多错误。我相信，有很多在线轮播示例只是从他人那里复制粘贴而从未尝试理解代码，相反，他们会不断添加更多的错误代码来解决他们可以“看到”的问题，请小心。

有许多无用的<div>包装程序和CSS样式旨在修复错误的行为，这显然会使调试过程变得更糟。

我建议您可以先查看官方文档，以了解这些组件的结构，然后根据SO的答案慢慢实现想法。

我只是从您的代码中删除其中大部分，仅用于演示目的。

为了使其具有响应性，我相信您必须修改js代码，以便它可以为不同的col-size和CSS填充轮播。但是似乎没有一种简单的方法可以解决CSS部分。

$(document).ready(function () {
  $('.fdi-Carousel .carousel-item').each(function () {
    var next = $(this).next();
    if (!next.length) {
      next = $(this).siblings(':first');
    }
    next.children(':first-child').clone().appendTo($(this));
    
    //this will only work for carousel with 3 items since it only adds next() and  next.next();

    if (next.next().length > 0) {
      next.next().children(':first-child').clone().appendTo($(this));
    }
    else {
      $(this).siblings(':first').children(':first-child').clone().appendTo($(this));
    }
  });
});

.carousel-control-prev-icon,
.carousel-control-next-icon {
  background-color: tomato !important;
}

.fdi-Carousel .carousel-inner .active.carousel-item,
.fdi-Carousel .carousel-inner .carousel-item-next,
.fdi-Carousel .carousel-inner .carousel-item-prev {
  display: flex;
} 

/* 'Again 33% means col-4, in order to make it responsive or whatever you want, you have to create different translateX()  for differernt col' */
.fdi-Carousel .carousel-inner .active.carousel-item-left, .fdi-Carousel .carousel-inner .carousel-item-prev {
  transform: translateX(-33.33%);
}
.fdi-Carousel .carousel-inner .active.carousel-item-right, .fdi-Carousel .carousel-inner .carousel-item-next {
  transform: translateX(33.33%);
}

.fdi-Carousel .carousel-inner .carousel-item-left, .fdi-Carousel .carousel-inner .carousel-item-right {
  transform: translateX(0);
  }

使用一些HTML和CSS修改来固定代码。该修复程序将使轮播图像以水平布局显示。这是我更改的内容列表

在轮播中为img添加了宽度
删除了div.col-md-4
已删除#outerCarousel
