引导轮播堆叠的图像和控件不起作用答案

【问题标题】：bootstrap carousel stacked images and controls not working引导轮播堆叠的图像和控件不起作用
【发布时间】：2017-11-23 01:32:25
【问题描述】：

我一直在到处寻找某种解决方案，但似乎没有一个对我有用！我有两张图片，但它们根本不滑动，它们只是堆叠在一起。控件甚至都没有显示，只显示第二张图片底部的指示器（堆栈上的底部图片）。我知道这可能与我在我的代码中错误地导入引导 CDN 有关，所以如果有人能提供帮助，将不胜感激，谢谢

【解决方案1】：

您从 Bootstrap 3 添加了轮播代码，并从 Bootstrap 4 添加了所需的文件。

查看我的代码：

【解决方案2】：

您似乎正在使用 Bootstrap 3 中的轮播代码。

可以在 here 找到 Bootstrap 4 轮播的文档。

例子：

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css" integrity="sha384-PsH8R72JQ3SOdhVi3uxftmaW6Vc51MKb0q5P2rRUpPvrszuE4W1povHYgTpBfshb" crossorigin="anonymous">

<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
  <ol class="carousel-indicators">
    <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
  </ol>
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img class="d-block w-100" src="http://via.placeholder.com/1600x800" alt="First slide">

    <div class="carousel-item">
      <img class="d-block w-100" src="http://via.placeholder.com/1600x800" alt="Second slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="http://via.placeholder.com/1600x800" alt="Third slide">
    </div>
  </div>
  <a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>

它有效！但是现在图像不会滑动并且控件不起作用，知道如何解决这个问题吗？
检查你的 JavaScript，看我的例子。
