Bootstrap Carousel无法正常工作（在页面上显示所有元素）

标签： javascript html css bootstrap-4 carousel

我正在尝试创建一个轮播。我已经创建了结构，但只希望出现五个块，然后在单击箭头后出现第六个块。我该怎么办？

我的方法 ：（采用from here）

img{
  border: 1px solid red;
  width: 100px;
  height: 100px;
  display: block;
}
ul{
  display: inline-block;
}
li{
  list-style-type: none;
}
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

<div id="myCarousel" class="carousel slide" data-ride="carousel">
  <div class="carousel-inner">
    <div class="item active">
      <!----------->
      <!-- CTA 1 -->
      <!----------->
      <ul class="clearfix">
        <li>
          <img src=""/>
          <span>Test 1</span>
        </li>
      </ul>
      <!----------->
      <!-- CTA 2 -->
      <!----------->
      <ul class="clearfix">
        <li>
          <img src=""/>
          <span>Test 2</span>
        </li>
      </ul>
      <!----------->
      <!-- CTA 3 -->
      <!----------->
      <ul class="clearfix">
        <li>
          <img src=""/>
          <span>Test 3</span>
        </li>
      </ul>
      <!----------->
      <!-- CTA 4 -->
      <!----------->
      <ul class="clearfix">
        <li>
          <img src=""/>
          <span>Test 4</span>
        </li>
      </ul>
      <!----------->
      <!-- CTA 5 -->
      <!----------->
      <ul class="clearfix">
        <li>
          <img src=""/>
          <span>Test 5</span>
        </li>
      </ul>
      <!----------->
      <!----------->

      <!-- TO APPEAR AFTER CONTROL CLICK -->

      <!----------->
      <!-- CTA 6 -->
      <!----------->
      <ul class="clearfix">
        <li>
          <img src=""/>
          <span>Test 6</span>
        </li>
      </ul>
    </div>
  </div>
  <!--=====================-->
  <!--== ON ARROW DISPLAY -==>  
  <!--=====================-->


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

如您所见，当前，它最初显示全部六个。不确定所链接的演示与我的方法之间有什么区别（当然还有结构）。

那是因为您将所有图像都保存在一个<div class="item">

中

以这种方式将它们保存在单独的div中：

<div class="item active">cat 1</div>
<div class="item">cat 2</div>
<div class="item">cat 3</div>
<div class="item">cat 4</div>
<div class="item">cat 5</div>
<div class="item">cat 6</div>

这应该像您预期的那样工作。添加了一个类为item的div。

img{
  border: 1px solid red;
  width: 100px;
  height: 100px;
  display: block;

ul{
  display: inline-block;

<div id="myCarousel" class="carousel slide" data-ride="carousel">
