如何仅通过单击下一个和上一个按钮来更改轮播的内容？

是否可以使轮播的内容不自动更改？我有这个属于 bootstrap 4 carousel 的代码，我想让 carousel 的内容只通过点击 prev 和 next 按钮显示。对于那些按钮（上一个和下一个），您能否更改它们的图标并为其指定名称和按钮形状？

这是代码：

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js"></script>

<div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img class="d-block w-100" src="img1.jpg" alt="First slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="img2.jpg" alt="Second slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="img3.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>

当然。使用data-interval="false". 您可以在这里找到所有选项：https : //www.w3schools.com/bootstrap4/bootstrap_ref_js_carousel.asp
