本文介绍在banner轮播基础上实现播放视频功能，有两种播放方式：
1、点击播放按钮，在banner图位置播放视频（效果如下）；
2、点击播放按钮，全屏播放视频。
1、两种播放方式，css样式共用如下：
* { padding: 0; margin: 0;}.swiper-contAIner { width: 100%; height: 211px;}.video { position: absolute; z-index: 1; top: 0; left: 0; width: 100%; height: 100%; display: none; background-color: rgba(0, 0, 0, 0.5);}.loading-box { width: 100%; position: absolute; top: 0; left: 0; height: 100%; font-size: 0;}.loading-box .video-img { width: 100%; height: 100%;}.loading-box .palying-img { position: absolute; top: 50%; left: 50%; transform: translateX(-50%) translateY(-50%); opacity: 1; transition: opacity 0.3s;}.loading-box .loading-img { position: absolute; top: 50%; left: 50%; transform: translateX(-50%) translateY(-50%); opacity: 0; transition: opacity 0.3s;}.loading-box.loading .loading-img { animation: loading 1s infinite; -webkit-animation: loading 1s infinite; opacity: 1;}.loading-box.loading .palying-img { display: none;}.diy-buttons { overflow: hidden; text-align: center;}.diy-buttons a { float: left; width: 50%;}@keyframes loading { from { transform: translateX(-50%) translateY(-50%) rotate(0deg); } to { transform: translateX(-50%) translateY(-50%) rotate(360deg); }}
2、第一种播放方式，html和js代码如下：
1）“onSlideChangeEnd”用来轮播结束回调函数“removeLoading”，移除加载效果，解决切换过快有时候还显示加载效果；
2）由于swiper为了循环轮播，复制了多一份数据，所以里面的video获取未使用ID；
3）监听video的状态“play”和“pause”来控制轮播或暂停轮播，增加体验。

3、第二种播放方式，html和js代码如下：
1）使用“webkitEnterFullScreen”全屏播放，兼容性比较好，可以在Android/ target=_blank class=infotextkey>安卓和苹果正常使用。
