我刚开始使用Bootstrap4,正在网站中实现“轮播和下拉菜单”。但是,每当我在下拉菜单或轮播指示器上单击时,它们似乎都无法正常工作,它会在URL中添加ID并再次显示在页面顶部。以下是代码。

    <div class="col-md-6">
    <!-- http://w3widgets.com/responsive-slider/img/slide-2.jpg -->
    <div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
      <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">
          <img class="d-block w-100" src="http://w3widgets.com/responsive-slider/img/slide-2.jpg" alt="First slide">
          <div class="carousel-caption d-none d-md-block">
            <h5>...</h5>
            <p>...</p>
          </div>
        </div>
        <div class="carousel-item">
          <img class="d-block w-100" src="http://w3widgets.com/responsive-slider/img/slide-2.jpg" alt="Second slide">
          <div class="carousel-caption d-none d-md-block">
            <h5>...</h5>
            <p>...</p>
          </div>
        </div>
        <div class="carousel-item">
          <img class="d-block w-100" src="http://w3widgets.com/responsive-slider/img/slide-2.jpg" alt="Third slide">
          <div class="carousel-caption d-none d-md-block">
            <h5>...</h5>
            <p>...</p>
          </div>
        </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>
</div>

我已包含所有必需的CSS(bootstrap.min.css)JS(jQuery, Popper, bootstrap.min.js)

我不知道出了什么问题。它甚至也没有在控制台中显示任何类型的错误或警告。
