kikay 人气:0

Bootstrap 轮播(Carousel)插件是一种灵活的响应式的向站点添加滑块的方式。

0x01 基本实例

Bootstrap实现轮播幻灯片的效果,只需要简单地使用class开发就可以了:

<!DOCTYPE html>
<html lang="zh-cn">
<head>
 <meta charset="UTF-8">
 <meta name="viewport" content="width=device-width, initial-scale=1">
 <link href="../../css/bootstrap.min.css" rel="stylesheet">
 <script src="http://cdn.bootcss.com/jquery/1.11.1/jquery.min.js"></script>
 <script src="../../js/bootstrap.min.js"></script>
 <title>轮播幻灯片</title>
</head>
<body>
<div class="container col-md-4 col-md-offset-4">
 <div id="myCarouel" class="carousel slide">
 <!--幻灯片切换指标-->
 <ol class="carousel-indicators">
  <li data-toggle="#myCarouel" data-slide-to="0" class="active"></li>
  <li data-toggle="#myCarouel" data-slide-to="1"></li>
  <li data-toggle="#myCarouel" data-slide-to="2"></li>
 </ol>
 <!--幻灯片项目-->
 <div class="carousel-inner">
  <div class="item active">
  <img src="../../img/slide1.png" alt="项目1">
  </div>
  <div class="item">
  <img src="../../img/slide2.png" alt="项目2">
  </div>
  <div class="item">
  <img src="../../img/slide3.png" alt="项目3">
  </div>
 </div>
 <!--幻灯片导航-->
 <a class="carousel-control left" href="#myCarouel" data-slide="prev"><<<</a>
 <a class="carousel-control right" href="#myCarouel" data-slide="next">>>></a>
 </div>
</div>
</body>
</html>

效果如下:

几点说明:

(1)属性 data-slide 接受关键字 prev 或 next,用来改变幻灯片相对于当前位置的位置。
(2)使用 data-slide-to 来向轮播传递一个原始滑动索引,data-slide-to="2" 将把滑块移动到一个特定的索引,索引从 0 开始计数。
(3)data-ride="carousel" 属性用于标记轮播在页面加载时就开始动画播放。

0x02 添加标题

可以通过.item内的.carousel-caption 元素向幻灯片添加标题:

<!DOCTYPE html>
<html lang="zh-cn">
<head>
 <meta charset="UTF-8">
 <meta name="viewport" content="width=device-width, initial-scale=1">
 <link href="../../css/bootstrap.min.css" rel="stylesheet">
 <script src="http://cdn.bootcss.com/jquery/1.11.1/jquery.min.js"></script>
 <script src="../../js/bootstrap.min.js"></script>
 <title>添加标题</title>
</head>
<body>
<div class="container col-md-4 col-md-offset-4">
 <div id="myCarouel" class="carousel slide">
 <!--幻灯片切换指标-->
 <ol class="carousel-indicators">
  <li data-toggle="#myCarouel" data-slide-to="0" class="active"></li>
  <li data-toggle="#myCarouel" data-slide-to="1"></li>
  <li data-toggle="#myCarouel" data-slide-to="2"></li>
 </ol>
 <!--幻灯片项目-->
 <div class="carousel-inner">
  <div class="item active">
  <img src="../../img/slide1.png" alt="项目1">
  <div class="carousel-caption">标题1</div>
  </div>
  <div class="item">
  <img src="../../img/slide2.png" alt="项目2">
  <div class="carousel-caption">标题2</div>
  </div>
  <div class="item">
  <img src="../../img/slide3.png" alt="项目3">
  <div class="carousel-caption">标题3</div>
  </div>
 </div>
 <!--幻灯片导航-->
 <a class="carousel-control left" href="#myCarouel" data-slide="prev"><<<</a>
 <a class="carousel-control right" href="#myCarouel" data-slide="next">>>></a>
 </div>
</div>
</body>
</html>

效果如下:

0x03 JS切换

还可以利用JS来实现幻灯片的切换。下面添加一些按钮来实现幻灯片的控制:

<!DOCTYPE html>
<html lang="zh-cn">
<head>
 <meta charset="UTF-8">
 <meta name="viewport" content="width=device-width, initial-scale=1">
 <link href="../../css/bootstrap.min.css" rel="stylesheet">
 <script src="http://cdn.bootcss.com/jquery/1.11.1/jquery.min.js"></script>
 <script src="../../js/bootstrap.min.js"></script>
 <title>JS切换</title>
</head>
<body>
<div class="container col-md-6 col-md-offset-3">
 <div id="myCarouel" class="carousel slide">
 <!--幻灯片切换指标-->
 <ol class="carousel-indicators">
  <li data-toggle="#myCarouel" data-slide-to="0" class="active"></li>
  <li data-toggle="#myCarouel" data-slide-to="1"></li>
  <li data-toggle="#myCarouel" data-slide-to="2"></li>
 </ol>
 <!--幻灯片项目-->
 <div class="carousel-inner">
  <div class="item active">
  <img src="../../img/slide1.png" alt="项目1">
  <div class="carousel-caption">标题1</div>
  </div>
  <div class="item">
  <img src="../../img/slide2.png" alt="项目2">
  <div class="carousel-caption">标题2</div>
  </div>
  <div class="item">
  <img src="../../img/slide3.png" alt="项目3">
  <div class="carousel-caption">标题3</div>
  </div>
 </div>
 <!--幻灯片导航-->
 <a class="carousel-control left" href="#myCarouel" data-slide="prev"><<<</a>
 <a class="carousel-control right" href="#myCarouel" data-slide="next">>>></a>
 <!--控制按钮-->
 <div style="text-align: center">
  <button type="button" class="btn start-slide">开始切换</button>
  <button type="button" class="btn pause-slide">终止切换</button>
  <button type="button" class="btn prev-slide">前一个幻灯</button>
  <button type="button" class="btn next-slide">后一个幻灯</button>
  <button type="button" class="btn slide-1">幻灯1</button>
  <button type="button" class="btn slide-2">幻灯2</button>
  <button type="button" class="btn slide-3">幻灯3</button>
 </div>
 </div>
</div>
<script>
 $(function () {
 //启动轮播
 $(".start-slide").click(function () {
  $("#myCarouel").carousel('cycle');
 })
 //终止轮播
 $(".pause-slide").click(function () {
  $("#myCarouel").carousel('pause');
 })
 //前一个幻灯
 $(".prev-slide").click(function () {
  $("#myCarouel").carousel('prev');
 })
 //下一个幻灯
 $(".next-slide").click(function () {
  $("#myCarouel").carousel('next');
 })
 //切换到指定的幻灯
 $(".slide-1").click(function () {
  $("#mycarouel").carousel(0);
 })
 $(".slide-2").click(function () {
  $("#mycarouel").carousel(1);
 })
 $(".slide-3").click(function () {
  $("#mycarouel").carousel(2);
 })
 })
</script>
</body>
</html>

效果如下:

0x04 事件

同样地,Carousel也定义了一些事件:

(1)slide.bs.carousel
当调用 slide 实例方法时立即触发该事件:

$('#mycarouel').on('slide.bs.carousel', function () {
 // 执行一些动作...
})

(2)slid.bs.carousel
当轮播完成幻灯片过渡效果时触发该事件:

$('#mycarouel').on('slid.bs.carousel', function () {
 // 执行一些动作...
})

看下面的例子:

<!DOCTYPE html>
<html lang="zh-cn">
<head>
 <meta charset="UTF-8">
 <meta name="viewport" content="width=device-width, initial-scale=1">
 <link href="../../css/bootstrap.min.css" rel="stylesheet">
 <script src="http://cdn.bootcss.com/jquery/1.11.1/jquery.min.js"></script>
 <script src="../../js/bootstrap.min.js"></script>
 <title>事件</title>
</head>
<body>
<div class="container col-md-4 col-md-offset-4">
 <div id="myCarouel" class="carousel slide">
 <!--幻灯片切换指标-->
 <ol class="carousel-indicators">
  <li data-toggle="#myCarouel" data-slide-to="0" class="active"></li>
  <li data-toggle="#myCarouel" data-slide-to="1"></li>
  <li data-toggle="#myCarouel" data-slide-to="2"></li>
 </ol>
 <!--幻灯片项目-->
 <div class="carousel-inner">
  <div class="item active">
  <img src="../../img/slide1.png" alt="项目1">
  </div>
  <div class="item">
  <img src="../../img/slide2.png" alt="项目2">
  </div>
  <div class="item">
  <img src="../../img/slide3.png" alt="项目3">
  </div>
 </div>
 <!--幻灯片导航-->
 <a class="carousel-control left" href="#myCarouel" data-slide="prev"><<<</a>
 <a class="carousel-control right" href="#myCarouel" data-slide="next">>>></a>
 </div>
</div>
<script>
 $(function () {
 $("#myCarouel").on('slide.bs.carousel',function () {
  alert('切换幻灯');
 });
 })
</script>
</body>
</html>

效果如下:
