vue实现视频循环并自动播放下一个

　　需求：循环播放视频，当前视频播放完自动播放下一条，可左右点击按钮播放。

• 下载videojs-contrib-hls

npm install --save-dev videojs-contrib-hls

• 新建 autovideo.vue

<template>
  <div id="home">
    <v-carousel
      :slideData="slideData"
      :height="500"
      :begin="0"
      :interval="3000"
      :dot="true"
      :arrow="true"
    ></v-carousel>
  </div>
</template>
<script>
import carousel from "./carousel";

export default {
  name: "home",
  components: {
    "v-carousel": carousel,
  },
  data() {
    return {

</script>
<style scoped>

• 新建 carousel.vue（需要自动循环播放的自行解注释）

<template>

          v-for="(item, index) in slideData"
          :key="index"
          v-show="index == beginValue"
          v-bind:style="{ height: height + 'px' }"
          style="display: flex"
        >
          <!-- 播放视频 -->
          <div v-for="(v, e) in item.videos" :key="e" class="videos">
            <video
