Bootstrap 3 Carousel - Divs或Panels？

Question

我正在尝试使用Bootstrap 3 Carousel来滑动我要创建的5个面板，但是我无法让它工作，因为它似乎只是幻灯片图像......有人管理过吗？

    <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">
      <div class="panel panel-default hidden" id="resultpanel" style="width: 60%; margin-left: auto; margin-right: auto; text-align: center;">
  <div class="panel-body">
    <p style="margin-left: auto; margin-right: auto; text-align: center;"><?php echo $_SESSION['printhis'] ?></p>
 </div>
</div>
      <div class="carousel-caption">
        ...
      </div>
    </div>
  </div>
