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。除此之外,内容也是足够灵活的,可以是图像、内嵌框架、视频或者其他您想要放置的任何类型的内容。
创新互联公司专业为企业提供坡头网站建设、坡头做网站、坡头网站设计、坡头网站制作等企业网站建设、网页设计与制作、坡头企业网站模板建站服务,10年坡头做网站经验,不只是建网站,更提供有价值的思路和整体网络服务。
如果您想要单独引用该插件的功能,那么您需要引用
carousel.js。或者,正如 Bootstrap 插件概览 一章中所提到,您可以引用
bootstrap.js 或压缩版的
bootstrap.min.js。
下面是一个简单的幻灯片,使用 Bootstrap 轮播(Carousel)插件显示了一个循环播放元素的通用组件。为了实现轮播,您只需要添加带有该标记的代码即可。不需要使用 data 属性,只需要简单的基于 class 的开发即可。

结果如下所示:
您可以通过 .item 内的 .carousel-caption 元素向幻灯片添加标题。只需要在该处放置任何可选的 HTML 即可,它会自动对齐并格式化。下面的实例演示了这点:

结果如下所示:
$('.carousel').carousel()
有一些选项是通过 data 属性或 JavaScript 来传递的。下表列出了这些选项:
选项名称 | 类型/默认值 | Data 属性名称 | 描述 |
---|---|---|---|
interval | number 默认值:5000 | data-interval | 自动循环每个项目之间延迟的时间量。如果为 false,轮播将不会自动循环。 |
pause | string 默认值:"hover" | data-pause | 鼠标进入时暂停轮播循环,鼠标离开时恢复轮播循环。 |
wrap | boolean 默认值:true | data-wrap | 轮播是否连续循环。 |
下面是一些轮播(Carousel)插件中有用的方法:
方法 | 描述 | 实例 |
---|---|---|
.carousel(options) | 初始化轮播为可选的 options 对象,并开始循环项目。 | |
.carousel('cycle') | 从左到右循环轮播项目。 | |
.carousel('pause') | 停止轮播循环项目。 | |
.carousel(number) | 循环轮播到某个特定的帧(从 0 开始计数,与数组类似)。 | |
.carousel('prev') | 循环轮播到上一个项目。 | |
.carousel('next') | 循环轮播到下一个项目。 | |
下面的实例演示了方法的用法:

结果如下所示:
下表列出了轮播(Carousel)插件中要用到的事件。这些事件可在函数中当钩子使用。
事件 | 描述 | 实例 |
---|---|---|
slide.bs.carousel | 当调用 slide 实例方法时立即触发该事件。 | |
slid.bs.carousel | 当轮播完成幻灯片过渡效果时触发该事件。 | |
