vue3环境下怎么改下面的代码让他自动播放<template> <div> <video ref="videoPlayer" @ended="playNextVideo"> <source :src="currentVideoSrc" type="video/mp4"> </video> </div> </template> <script> export default { data() { return { currentVideoIndex: 0, // 当前播放的视频索引 videoList: [ // 视频列表 { src: '/src/video/666.mp4' }, { src: '/src/video/777.mp4' }, { src: '' } ] } }, computed: { currentVideoSrc() { return this.videoList[this.currentVideoIndex].src } }, mounted() { this.$refs.videoPlayer.play() }, methods: { playNextVideo() { this.currentVideoIndex++ if (this.currentVideoIndex >= this.videoList.length) { this.currentVideoIndex = 0 } this.$refs.videoPlayer.src = this.currentVideoSrc this.$refs.videoPlayer.play() } } } </script>

可以在 `mounted()` 方法中使用 `setInterval()` 方法来实现自动播放。具体实现步骤如下:
1. 在 `data()` 中添加一个 `autoplayInterval` 变量,用于存储 `setInterval()` 的返回值。
2. 在 `mounted()` 方法中添加以下代码,实现自动播放:
```
this.autoplayInterval = setInterval(() => {
this.playNextVideo()
}, 5000)
```
其中,第一个参数是回调函数,第二个参数是时间间隔(单位为毫秒)。
3. 在 `beforeUnmount()` 方法中添加以下代码,清除 `setInterval()`:
```
clearInterval(this.autoplayInterval)
```
完整代码如下所示:
```
<template>
<div>
<video ref="videoPlayer" @ended="playNextVideo">
<source :src="currentVideoSrc" type="video/mp4">
</video>
</div>
</template>
<script>
export default {
data() {
return {
currentVideoIndex: 0, // 当前播放的视频索引
videoList: [ // 视频列表
{
src: '/src/video/666.mp4'
},
{
src: '/src/video/777.mp4'
},
{
src: ''
}
],
autoplayInterval: null // 自动播放的定时器
}
},
computed: {
currentVideoSrc() {
return this.videoList[this.currentVideoIndex].src
}
},
mounted() {
this.$refs.videoPlayer.play()
// 自动播放
this.autoplayInterval = setInterval(() => {
this.playNextVideo()
}, 5000)
},
beforeUnmount() {
// 清除定时器
clearInterval(this.autoplayInterval)
},
methods: {
playNextVideo() {
this.currentVideoIndex++
if (this.currentVideoIndex >= this.videoList.length) {
this.currentVideoIndex = 0
}
this.$refs.videoPlayer.src = this.currentVideoSrc
this.$refs.videoPlayer.play()
}
}
}
</script>
```
