Bootstrap 多个项目轮播（一次显示多个轮播项目）

Question

如何在 Bootstrap 4 中实现多项目轮播？文档提到了多个轮播，但没有提到包含多个项目的轮播。

Answer 1

您一次可以显示一个轮播项目，但可以用多个元素填充它。类似于：

.item
  .col-xs-4
     {content}
  .col-xs-4
     {content}
  .col-xs-4
     {content}

但是您可能希望一次推进一个。开箱即用的 bootstrap 不会发生这种情况。在实施了许多轮播后，我建议在 Bootstrap 不符合要求时寻找另一个轮播库。 Slick.js 是我的许多轮播配置选项的首选库。它是一个相当纤细的 ~5k min'd 和 gzipped。

如果您很难使用 bootstrap，这里有一个脚本可以提供单一的预付款，多个项目：http://codepen.io/MarkitDigital/pen/ZpEByz

Bootstrap 5 - 更新 2021

与早期版本一样，最好的方法是将多张幻灯片放在一张 carousel-item 中。这可以使用网格类...

来完成

<div class="carousel-item">
   <div class="row">
     <div class="col">slide 1</div>
     <div class="col">slide 2</div>
     <div class="col">slide 3</div>
     <div class="col">slide 4</div>
   </div>
</div>
<div class="carousel-item">
   <div class="row">
     <div class="col">slide 5</div>
     <div class="col">slide 6</div>
     <div class="col">slide 7</div>
     <div class="col">slide 8</div>
   </div>
</div>

以上代码将一次推进 4 张幻灯片。如果您希望轮播一次前进一张幻灯片、see this question.

Bootstrap 4 - 更新 2019

我使用 Bootstrap 4 网格完成了此操作，每个轮播项目都有单独的列。如果您一次只想推进一个项目，脚本可以像这样将幻灯片克隆到每个轮播项目中..

(function($) {
    "use strict";
    
    $('.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));
      }
    });
    
})(jQuery);

我正在研究 bootstrap 4。这段代码对我有用

这个包含六张图片的多轮播，每次都作为批量幻灯片。有空问我:)

2021 年更新 Bootstrap 5

受 Zims 方法的启发，我更新了样式表以使用 Bootstrap 5.

多项，一次移动一项：

var myCarousel = document.querySelector('#myCarousel')
var carousel = new bootstrap.Carousel(myCarousel, {
  interval: 100000
})

$('.carousel .carousel-item').each(function(){
    var minPerSlide = 4;
    var next = $(this).next();
    if (!next.length) {
    next = $(this).siblings(':first');
    }
    next.children(':first-child').clone().appendTo($(this));
    
    for (var i=0;i<minPerSlide;i++) {
        next=next.next();
        if (!next.length) {
            next = $(this).siblings(':first');
        }
        
        next.children(':first-child').clone().appendTo($(this));
      }
});

@media (max-width: 768px) {
  .carousel-inner .carousel-item > div {
    display: none;
  }
  .carousel-inner .carousel-item > div:first-child {
    display: block;
  }
}

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

/* display 4 */
@media (min-width: 768px) {
  .carousel-inner .carousel-item-right.active,
.carousel-inner .carousel-item-next,
.carousel-item-next:not(.carousel-item-start)
{
    transform: translateX(25%) !important;
  }

.carousel-inner .carousel-item-left.active, .carousel-item-prev:not(.carousel-item-end),
.active.carousel-item-start, .carousel-item-prev:not(.carousel-item-end)
{
    transform: translateX(-25%) !important;
}

.carousel-item-next.carousel-item-start {
  transform: translateX(0) !important;
}

.carousel-inner .carousel-item-prev,
.carousel-item-prev:not(.carousel-item-end)
{
    transform: translateX(-25%) !important;
  }
}

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

Answer 5

我在 html 中使用了这种结构，使轮播响应迅速，并且可以根据您需要的每张幻灯片的项目数轻松编辑。您可以在下面的 link 找到完整的代码。它需要 bootstrap 4.0.0、jquery 和 bootstrap js.

<div class="carousel-item col-md-6 active">
    <img class="img-fluid mx-auto d-block" src="//placehold.it/400x300?text=1" alt="slide 1">
  </div>
