一、第一部分html页面的准备
<van-swipe :show-indicators="false" :initial-swipe="showSlide" @change="onChange" vertical :loop="false" ref="vant_swipe" >
<van-swipe-item v-for="(item, index) in videoList" :key="index" class="product_swiper">
<div class="video_container">
<video class="video_box" width="100%" height="100%" webkit-playsinline="true" x5-playsinline x5-video-player-type="h5" x5-video-player-fullscreen="true" playsinline="true" preload="auto" :src="item.video_url" :playOrPause="playOrPause" x-webkit-airplay="allow" x5-video-orientation="portrait" @click="pauseVideo" @ended="onPlayerEnded($event)" loop="loop" :style="{opacity:isopacity}"></video>
<!-- 封面 -->
<img v-show="isVideoShow" class="play" @click="playvideo" :src="item.video_cover" :style="{opacity:isopacity}">
<img v-show="iconPlayShow" class="icon_play" @click="playvideo" src="static/images/icon_play.png">
</div>
<!-- 底部作品描述 -->
<div class="production_box">
<div class="production_name">{{item.title}}</div>
<div class="production_des">{{item.introduction}}</div>
</div>
</van-swipe-item>
</van-swipe>
二、数据说明部分
data() {
let u = navigator.userAgent;
return {
showSlide: 0,
allLoaded: false, //数据是否全部加载完
page: 1,
isLoading: true,
option: {},
current: 0,
videoList: [],
isVideoShow: true,
playOrPause: true,
video: null,
iconPlayShow: true,
isAndroid: u.indexOf("Android") > -1 || u.indexOf("Adr") > -1, // android终端
isiOS: !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/), // ios终端
tabIndex: 0,
showshare: false,
videoInterval: null, //检查视频是否加载好
videoLazy: false, //视频懒加载
isopacity: 1,
shareVideo: null, //点击分享的时候需要暂停的视频
dataLoaded: false
};
},
三、事件
//滑动改变播放的视频
onChange(index) {
//如果已经播放第一个了就清除循环

//改变的时候 暂停当前播放的视频

}
