javascript - 轮播在最新的 Bootstrap 版本中不起作用

问题描述

我一直在尝试制作一个简单的旋转木马，但由于某种原因无法使其正常工作。我尝试仅使用 Bootstrap 文档提供的示例代码，即使这样它也不能按预期工作。（幻灯片不会通过，下一个/上一个按钮不起作用）

使用 CDN 中较旧版本的 Bootstrap JS 是可行的，但是当使用 Bootstrap 4.5+ 时，它就无法正常工作。

这是代码（几乎所有内容都来自文档）：

<!doctype html>
<html lang="en">
  <head>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <!-- Bootstrap CSS -->
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta1/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-giJF6kkoqNQ00vy+HMDP7azOuL0xtbfIcaT9wjKHr8RbDVddVHyTfAAsrekwKmP1" crossorigin="anonymous">

        <div class="carousel-item active">

        <div class="carousel-item">

        </div>
        <div class="carousel-item">
          <img class="d-block w-100" src="img/carousel3.jpg" alt="Third slide">
        </div>
      </div>
      <a class="carousel-control-prev" href="#carouselExampleControls" 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="#carouselExampleControls" role="button" data-slide="next">
        <span class="carousel-control-next-icon" aria-hidden="true"></span>
        <span class="sr-only">Next</span>
      </a>
    </div>

    <!-- Optional JavaScript; choose one of the two! -->

    <!-- Option 1: Bootstrap Bundle with Popper -->
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta1/dist/js/bootstrap.bundle.min.js" integrity="sha384-ygbV9kiqUc6oa4msXn9868pTtWMgiQaeYH7/t7LECLbyPA2x65Kgf80OJFdroafW" crossorigin="anonymous"></script>

    <!-- Option 2: Separate Popper and Bootstrap JS -->
    <!--
    <script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.5.4/dist/umd/popper.min.js" integrity="sha384-q2kxQ16AaE6UbzuKqyBE9/u/KzioAlnx2maXQHiDX9d4/zp8Ok3f+M7DPm+Ib6IU" crossorigin="anonymous"></script>

任何帮助将不胜感激，谢谢。

解决方案

您只是在数据属性名称中打错了字。
您的代码在更改 this:
data-slide="prev"并更改data-slide="next"
为 this:
data-bs-slide="prev"和data-bs-slide="next"

<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta1/dist/css/bootstrap.min.css" rel="stylesheet" />
<div id="carouselExampleControls" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img class="d-block w-100" src="https://via.placeholder.com/300.png?text=carousel1" alt="First slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="https://via.placeholder.com/300.png?text=carousel2" alt="Second slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="https://via.placeholder.com/300.png?text=carousel3" alt="Third slide">
    </div>
  </div>
  <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-bs-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="#carouselExampleControls" role="button" data-bs-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>


</div>

<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta1/dist/js/bootstrap.bundle.min.js" integrity="sha384-ygbV9kiqUc6oa4msXn9868pTtWMgiQaeYH7/t7LECLbyPA2x65Kgf80OJFdroafW" crossorigin="anonymous"></script>
