利用BootStrap的Carousel.js实现轮播图动画效果

以下是“利用BootStrap的Carousel.js实现轮播图动画效果”的完整攻略。

步骤一：引入Bootstrap和JQuery库

<!-- 引入Bootstrap样式 -->

<link rel="stylesheet" href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css">

<!-- 引入Bootstrap库文件 -->

<script src="https://cdn.bootcss.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

<!-- 引入jQuery库文件 -->

<script src="http://code.jquery.com/jquery-1.12.4.min.js"></script>

步骤二：编写轮播图HTML结构

<div id="myCarousel" class="carousel slide">

  <!-- 轮播图指示器 -->
  <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>
  </ol>

  <!-- 轮播图内容 -->
  <div class="carousel-inner">
    <div class="item active">
      <img src="img/carousel1.jpg" alt="">
      <div class="carousel-caption">
        <h3>First slide label</h3>
        <p>Nulla vitae elit libero, a pharetra augue mollis interdum.</p>
      </div>
    </div>
    <div class="item">
      <img src="img/carousel2.jpg" alt="">
      <div class="carousel-caption">
        <h3>Second slide label</h3>
        <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
      </div>
    </div>
    <div class="item">
      <img src="img/carousel3.jpg" alt="">
      <div class="carousel-caption">
        <h3>Third slide label</h3>
        <p>Praesent commodo cursus magna, vel scelerisque nisl consectetur.</p>
      </div>
    </div>
  </div>

  <!-- 轮播图控制 -->
  <a class="left carousel-control" href="#myCarousel" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left"></span>
  </a>
  <a class="right carousel-control" href="#myCarousel" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right"></span>
  </a>

</div>

步骤三：初始化轮播图

$(document).ready(function(){
  // 初始化轮播图
  $('#myCarousel').carousel({
    interval: 3000 // 轮换间隔时间
  });
});

至此，一个简单的轮播图已经完成了。其中，carousel-indicators表示指示器，carousel-inner表示轮播内容，carousel-control表示轮播控制，这三者相互配合实现轮播图的功能。

以下是两个轮播图的示例说明：

示例一：轮播图带标题

<div id="myCarousel" class="carousel slide">

  <!-- 轮播图指示器 -->
  <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>
  </ol>

  <!-- 轮播图内容 -->
  <div class="carousel-inner">
    <div class="item active">
      <img src="img/carousel1.jpg" alt="">
      <div class="carousel-caption">
        <h3>First slide label</h3>
        <p>Nulla vitae elit libero, a pharetra augue mollis interdum.</p>
      </div>
    </div>
    <div class="item">
      <img src="img/carousel2.jpg" alt="">
      <div class="carousel-caption">
        <h3>Second slide label</h3>
        <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
      </div>
    </div>
    <div class="item">
      <img src="img/carousel3.jpg" alt="">
      <div class="carousel-caption">
        <h3>Third slide label</h3>
        <p>Praesent commodo cursus magna, vel scelerisque nisl consectetur.</p>
      </div>
    </div>
  </div>

  <!-- 轮播图控制 -->
  <a class="left carousel-control" href="#myCarousel" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left"></span>
  </a>
  <a class="right carousel-control" href="#myCarousel" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right"></span>
  </a>

</div>

示例二：自动轮播图

<div id="myCarousel" class="carousel slide">

  <!-- 轮播图指示器 -->
  <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>
  </ol>

  <!-- 轮播图内容 -->
  <div class="carousel-inner">
    <div class="item active">
      <img src="img/carousel1.jpg" alt="">
    </div>
    <div class="item">
      <img src="img/carousel2.jpg" alt="">
    </div>
    <div class="item">
      <img src="img/carousel3.jpg" alt="">
    </div>
  </div>

  <!-- 轮播图控制 -->
  <a class="left carousel-control" href="#myCarousel" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left"></span>
  </a>
  <a class="right carousel-control" href="#myCarousel" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right"></span>
  </a>

</div>

以上两个示例分别展示了轮播图带标题和自动轮播两种不同的效果。注意，轮播控制中的href和data-slide属性指明了轮播图的上一张和下一张，分别为prev和next，需要根据情况修改。
