vue3 videojs实现播放器，动态更改src
1.vue框架更改对应数据data，对应的视图view变化。2.在封装的组件监听传参src的变化，如果点击的 src和之前的不同，进行切换资源，播放器重新加载播放；3.播放器的资源source的参数有src+type，注意type可以不设置。推荐用法：不设置type，如果要设置一定要更传过来的视频流的数据格式保持一致，否则会爆红。
·
一、背景
vue3下载第三方插件videojs，达到播放器的效果，并且点击事件能够动态更改播放器的src。实现思路：
- 场景一：只有一个播放器，当点击事件，直接赋值，动态更改封装好的组件的src参数，能够实现切换播放器的效果。
- 场景二：不止有一个窗口，而是多窗口，要选中多个窗口中的一个窗口，然后点击，达到动态切换选中播放器的src。
二、实现总结
1.vue框架更改对应数据data，对应的视图view变化。
2.在封装的组件监听传参src的变化，如果点击的 src和之前的不同，进行切换资源，播放器重新加载播放；
3.播放器的资源source的参数有src+type，注意type可以不设置。
推荐用法：不设置type，如果要设置一定要更传过来的视频流的数据格式保持一致，否则会爆红。

四、完整代码
(一)、封装组件
组件封装，videojs封装成一个组件：
完整代码：
<script setup lang="ts">
import { computed, CSSProperties, onMounted, ref, watch } from 'vue'
import videojs from 'video.js'
import type { VideoJsPlayerOptions } from 'video.js'
import 'video.js/dist/video-js.min.css'
type MyVideoProps = {
/** 视频地址 */
src: string
width?: string
height?: string
}
const props = withDefaults(defineProps<MyVideoProps>(), {})
// video标签
const videoRef = ref<HTMLElement | null>(null)
// video实例对象
let videoPlayer: videojs.Player | null = null
const videoWrapStyles = computed<CSSProperties>(() => {
return {
width: props.width || '100%',
height: props.height || '100%'
}
})
// 初始化videojs
const initVideo = () => {
// https://gitcode.gitcode.host/docs-cn/video.js-docs-cn/docs/guides/options.html
const options: VideoJsPlayerOptions = {
language: 'zh-CN', // 设置语言
controls: true, // 是否显示控制条
preload: 'auto', // 预加载
autoplay: true, // 是否自动播放
fluid: false, // 自适应宽高
src: props.src, // 要嵌入的视频源的源 URL
objectFit: 'cover', // 同css object-fit，作用于video标签
notSupportedMessage: 'Ajiang此视频暂无法播放，请稍后再试' //允许覆盖Video.js无法播放媒体源时显示的默认信息。
}
if (videoRef.value) {
// 创建 video 实例
videoPlayer = videojs(videoRef.value, options, onPlayerReady)
}
}
// video初始化完成的回调函数
const onPlayerReady = () => { }
onMounted(() => {
initVideo()
})
watch(() => props.src, (now) => {
if (now) {
videoPlayer.pause()
// videoPlayer.dispose()
videoPlayer.reset()
setTimeout(() => {
videoPlayer.src([
{
src: props.src,
// type: "application/x-mpegURL" //type可以不写，一旦写了一定要符合否则报错
}
])
videoPlayer.load()
videoPlayer.play()
}, 10)
}
})
</script>
<template>
<div :style="videoWrapStyles">
<video id="my-player" ref="videoRef" class="video-js w-full h-full">
<source :src="src" />
</video>
</div>
</template>
<style lang="less" scoped>
.w-full {
width: 100%;
}
.h-full {
height: 100%;
}
</style>
(二)、局部引入
页面引入，引入封装的组件：

封装组件的监听watch:

videoPlayer.reset()
setTimeout(() => {

}
])
videoPlayer.load()
videoPlayer.play()

const changePlayer = (id) => {
console.log('ddd>>>', id, typeof id);
//2.如何获取到多个播放器中的一个？
data.currentPlayerId = id
}
const handleNodeClick = (treeNode, node) => {
if (node.level !== 1) {
if (data.cruentIndex !== 0) {
data.videoUrlData[data.currentPlayerId].url = treeNode.url //变data，变视频
} else {
data.videoUrlData[0].url = treeNode.url
}
} else {

}
