Question

我正在尝试使用引导程序执行全页着陆图像滑块，但是它不起作用，并且在控制台日志中，出现错误“无法读取..........的未定义属性'offsetWidth'” ..“

.carousel-item {
  height: 100vh;
  min-height: 350px;
  background: no-repeat center center scroll;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

<header>
  <div id="carouselExampleIndicators" 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" role="listbox">
      <!-- Slide One - Set the background image for this slide in the line below -->
      <div class="carousel-item active" style="background-image: url('https://source.unsplash.com/LAaSoL0LrYs/1920x1080')">
        <div class="carousel-caption d-none d-md-block">
          <h2 class="display-4">First Slide</h2>
          <p class="lead">This is a description for the first slide.</p>

        </div>
      </div>
    </div>
    <a class="carousel-control-prev" href="#carouselExampleIndicators" 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="#carouselExampleIndicators" role="button" data-slide="next">
      <span class="carousel-control-next-icon" aria-hidden="true"></span>
      <span class="sr-only">Next</span>
    </a>
  </div>
</header>
