这是我从 http://bootstrapbay.com/blog/bootstrap-3-carousel-tutorial/ 获得的轮播教程代码.轮播下一个按钮和轮播虚线按钮不起作用。我不知道会发生什么。请帮我解决这个问题。我把图像和红色按钮确定不起作用的按钮。

<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
      <!-- Indicators -->
      <ol class="carousel-indicators">
        <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
        <li data-target="#carousel-example-generic" data-slide-to="1"></li>
        <li data-target="#carousel-example-generic" data-slide-to="2"></li>
      </ol>

      <!-- Wrapper for slides -->
      <div class="carousel-inner">
        <div class="item active">
          <img src="http://placehold.it/1200x315" alt="...">
          <div class="carousel-caption">
              <h3>Caption Text</h3>
          </div>
        </div>
        <div class="item">
          <img src="http://placehold.it/1200x315" alt="...">

        </div>
        <div class="item">

          <div class="carousel-caption">
              <h3>Caption Text</h3>
          </div>
        </div>
      </div>

作为 tutorial you linked in the question 的第 2 步说，你必须添加以下标签来添加 jquery(顺序很重要):

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="js/bootstrap.min.js"></script>
