Question

所以，我的图片不会显示在我的旋转木马中。我试过多次更改名称，没有任何反应。我甚至把图像放到了img文件夹中。我顺便使用了灰度模板。有人可以解释一下吗？

<div class="container">
  <br>
  <div id="myCarousel" class="carousel slide" data-ride="carousel">
    <!-- Indicators -->
    <ol class="carousel-indicators">
      <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
      <li data-target="#myCarousel" data-slide-to="1"></li>
      <li data-target="#myCarousel" data-slide-to="2"></li>
      <li data-target="#myCarousel" data-slide-to="3"></li>
    </ol>

    <!-- Wrapper for slides -->
    <div class="carousel-inner" role="listbox">
      <div class="item active">
        <img src="store" alt="store" width="460" height="345">
      </div>

      <div class="item">
        <img src="art.jpg" alt="art" width="460" height="345">
      </div>

      <div class="item">
        <img src=".jpg" alt="Flower" width="460" height="345">
      </div>

      <div class="item">
        <img src="img_flower2.jpg" alt="Flower" width="460" height="345">
      </div>
    </div>

    <!-- Left and right controls -->
    <a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
      <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
      <span class="sr-only">Previous</span>
    </a>
    <a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
      <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
      <span class="sr-only">Next</span>
    </a>
  </div>
</div>

Answer 1

这里有多个问题：

查看the carousel example后，包装器下的容器（即<div class="carousel-inner" role="listbox">）似乎缺少类 carousel-item

<div class="item">
    <img src="art.jpg" alt="art" width="460" height="345">`

所以添加该类名：

<div class="item carousel-item">
    <img src="art.jpg" alt="art" width="460" height="345">`

图片代码的某些源属性似乎包含无效的文件名 - 例如<img src="store" alt="store" width="460" height="345">
除非你不想要它们（也许你有不同的图标），下一个和前一个图标容器缺少类 icon-prev 和 icon-next ：<span class="glyphicon glyphicon-chevron-left icon-prev" aria-hidden="true"></span>
此外，您可能已经这样做了，但确保添加了所需的CSS和JS文件（请参阅Quick start部分）。

Answer 2

您的代码显示某些图片src属性没有扩展名，有些没有名称和扩展名。您的src属性也一定存在问题，因为您可能没有放置正确的图像路径。

<img src="store" alt="store" width="460" height="345">
<img src=".jpg" alt="Flower" width="460" height="345">
