Question

我无法弄清楚旋转木马无法正常工作的原因。我认为问题是脚本放置，但不能把手指放在上面。我也有功能的导航栏代码，我省略了。帮助

您的代码实际上正在按预期工作，“仅限幻灯片”Bootstrap轮播只需要一段时间（约5秒）即可触发：

<!doctype html>
<html lang="en">

  <!-- Required meta tags -->
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

  <link rel="stylesheet" href="css/styles.css">
</head>

<body>
  <div id="carouselExampleSlidesOnly" class="carousel slide" data-ride="carousel">
    <div class="carousel-inner">
      <div class="carousel-item active">
        <img class="d-block w-100" src="http://placehold.it/100" alt="First slide">
      </div>
      <div class="carousel-item">
        <img class="d-block w-100" src="http://placehold.it/100" alt="Second slide">
      </div>
      <div class="carousel-item">
        <img class="d-block w-100" src="http://placehold.it/100" alt="Third slide">
      </div>
    </div>
  </div>

如果您更换为可以手动控制的旋转木马，这里是一个带控件的工作旋转木马：

<!doctype html>

  <!-- Required meta tags -->
  <meta charset="utf-8">

  <link rel="stylesheet" href="css/styles.css">
</head>

<body>
  <div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
    <div class="carousel-inner" role="listbox">
      <div class="carousel-item active">
        <img class="d-block img-fluid" src="http://placehold.it/600" alt="First slide">
      </div>
      <div class="carousel-item">
        <img class="d-block img-fluid" src="http://placehold.it/600" alt="Second slide">
      </div>
      <div class="carousel-item">
        <img class="d-block img-fluid" src="http://placehold.it/600" 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>
