jquery - 如何仅通过单击下一个和上一个按钮来更改轮播的内容？

Question

是否可以让轮播的内容不自动改变？我有属于 bootstrap 4 旋转木马的代码，我想让旋转木马的内容仅通过单击上一个和下一个按钮显示。对于那些按钮(上一个和下一个)，您可以更改它们的图标并为其命名和按钮形状吗？

这是代码:

<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
