javascript - 如何通过单击轮播项目内的按钮转到下一个轮播项目

Question

我正在尝试在 Bootstrap 4 中创建一个轮播，其中轮播项目内有一个下一个按钮。当我单击下一个按钮时，我想移至下一个轮播。

<div class="container">
  <div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel" data-interval='false'>
    <ol class="carousel-indicators">
      <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
      <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
      <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
    </ol>
    <div class="carousel-inner ">
      <div class="carousel-item active">
        <button type="submit" class="btn btn-primary" id="gotoNext1">Next</button>
        <img src="https://placehold.it/900x350/e8117f/fff&text=Image%201" alt="Image 1"/>        
      </div>
      <div class="carousel-item">
        <button type="submit" class="btn btn-primary" id="gotoNext2">Next</button>
        <img src="https://placehold.it/900x350/9ACD32/fff&text=Image%202" alt="Image 2"/>
      </div>
      <div class="carousel-item">
        <img src="https://placehold.it/900x350/FF6347/fff&text=Image%203" alt="Image 3"/>
      </div>
    </div>        
  </div>
</div>

请问有人可以帮助我使用 Javascript 或 jquery 实现此功能吗？

我可以使用轮播指示器移动下一个或上一个，但我想使用按钮前进。

请参阅jsfiddle link了解更多详情...

您可以使用.carousel("next")来自JQuery:

$("button").click(() => $(".carousel").carousel("next"));
