vue video 多个视频切换后视频不显示的解决方法

先说一下我这边的需求是视频需要轮播，一个人员有多个视频，左右轮播是轮播某个人员下的视频，上下切换是切换人员。

vue 代码

      <el-carouselindicator-position="none"ref="carousel"arrow="always":interval="10000"@change="carouselChange"><transition name="carousel-arrow-right"><buttontype="button"@click="arrowDown('top')"class="el-carousel__arrow el-carousel__arrow--right el-carousel__arrow--top"><i class="el-icon-arrow-up"></i></button></transition><transition name="carousel-arrow-right"><button@click="arrowDown('bottom')"type="button"class="el-carousel__arrow--bottom"><i class="el-icon-arrow-down"></i></button></transition><!--   --><el-carousel-itemv-for="(item, index) in videoUrl":key="index"v-loading="loading"element-loading-spinner=" "element-loading-background="rgba(0, 0, 0, 0.8)"@mouseenter.native="autoplayHandler"><template v-if="isPlayer"><div style="margin: 5px 0">{{ '张三' }}</div><div style="width: 100%; height: 76%" id="video-box"><video:id="`my-video${index}`"class="video-js vjs-default-skin"controlspreload="auto"><source :src="item.monitorUrl" type="application/x-mpegURL" /></video></div></template></el-carousel-item></el-carousel>

js代码：

export default {data() {return {videoUrl: [],arr: [{name: "张三",videoUrlList: [{monitorUrl:"https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8",},{monitorUrl:"https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8",},{monitorUrl:"https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8",},],},{name: "李四",videoUrlList: [{monitorUrl:"https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8",},],},],selectionObj:{},DownIndex: 0,player: [],isPlayer: true,};},mounted() {let _that = this;//默认取第一个_that.selectionObj=arr[0]setTimeout(() => {_that.getVideo();}, 6000);},//销毁事件beforeDestroy() {this.clearVideo();},methods: {//销毁视频clearVideo() {if (this.player != null) {for (let i = 0; i < this.player.length; i++) {this.player[i].dispose(); //dispose()是官方的销毁函数}}},//初始化getVideo() {const _this = this;//判断视频是否存在如果存在不需要重新初始化if(_this.player.length!=0) returnthis.videoUrl.map((item,index) => {let player = videojs(`my-video${index}`,{bigPlayButton: false,textTrackDisplay: false,posterImage: true,errorDisplay: false,controlBar: true,// restoreEl: true,autoplay: true, //是否自动播放muted: true, //静音模式 、、 解决首次页面加载播放},function () {// this.reset()//视频中重置方法 this.load();//刷新视频地址_this.player.push(player);//player是一个空数组 存放实例化的视频实例});});},//监控上下切换arrowDown(type) {//点切换是销毁视频this.clearVideo();this.isPlayer = false; //切换后const arr= this.arr;const index =type == "top"? this.DownIndex == 0? this.arr.length - 1: this.DownIndex - 1: this.DownIndex == this.arr.length - 1? 0: this.DownIndex + 1;this.DownIndex = index;this.$nextTick(() => {this.canteenObj = {};this.videoUrl = [];if (arr&& arr[this.DownIndex].videoUrlList) {this.selectionObj= canteenList[this.DownIndex];this.videoUrl = canteenList[this.DownIndex].videoUrlList;// this.loading = true;this.isPlayer = true; //切换后}//切换到轮播第一页this.$refs.carousel.setActiveItem(0);// videoBox.load()this.carouselChange(0);// this.getVideo(index);});},//监控视频切换播放carouselChange(index) {// returnsetTimeout(() => {this.isPlayer = true;this.getVideo(index);}, 6000);},// 轮播图鼠标移入清除时间函数autoplayHandler(index) {this.$refs.carousel.pauseTimer();},}}

样式：

 <style scoped>
>>> .el-carousel,
>>> .el-carousel__container {height: 100%;
}
>>> .video-js {height: calc(100% - 6px);width: 100%;
}
.el-carousel__arrow--top {top: 0px;left: 46%;transform: translate(-50%, 0);
}
.el-carousel__arrow--bottom {bottom: 5px;position: absolute;left: 50%;height: 36px;width: 36px;border-radius: 50%;background-color: rgba(31, 45, 61, 0.11);color: #ffffff;border: none;outline: none;z-index: 10;transform: translate(-50%, 0);
}
</style>
