Bootstrap 4轮播不工作？

Question

我有以下 BS4 轮播代码，（使用本教程制作的 https://www.youtube.com/watch?v=n8ItscKLf7s&list=PLRtjMdoYXLf47brThg9-nTj8HSq8cQ0ND&index=53），但是代码不起作用，显示了第一张图片，但我不知道轮播不受控制的原因是什么，无论如何它都不会转到下一张图片。可能的解决方案是什么？

<div class="container">
        <div class="row">
            <div class="col-xs-12 col-sm-12 col-md-12 col-lg-12 col-xl-12">
                <br />
                <div id="carousel-example-generic" class="carousel-slide" data-ride="carousel">
                    <ol class="carousel-indicators">
                    <li data-target="#carousel-example-generic" data-slide-to="0" class="active"> </li>
                     <li data-target="#carousel-example-generic" data-slide-to="1"> </li>
                     <li data-target="#carousel-example-generic" data-slide-to="2"> </li>
                    </ol>

                    <div class="carousel-inner" role="listbox">
                        <div class="carousel-item-active">
                            <img src="images/1.jpeg" alt="First-Slide">
                        </div>
                        <div class="carousel-item">
                            <img src="images/2.jpeg" alt="Second-Slide">
                        </div>
                        <div class="carousel-item">
                            <img src="images/3.jpeg" alt="Third-Slide">
                        </div>
                    </div>
                    <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev"> 
                    <span class="icon-prev" aria-hidden="true"></span>
                    <span class="sr-only"> Previous </span>
                    </a>
                    <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next"> 
                    <span class="icon-next" aria-hidden="true"></span>
                    <span class="sr-only"> Next </span>
                    </a>
                </div>
            </div>
        </div>
    </div>

Answer 1

小错误。 class="carousel-item-active" 应该是 class="carousel-item active"。不是一个class。您已将 active class 与 carousel-item class 合并。那是错误的。

<div class="carousel-item-active">
  <img src="images/1.jpeg" alt="First-Slide">
</div>

应该改为

<div class="carousel-item active">
  <img src="images/1.jpeg" alt="First-Slide">
</div>
