当全屏从外部组件切换时，取消静音react播放器

Question

我有一个VideoItem-和Player-组件

在VideoList中，单击一个按钮并进入全屏模式(按预期工作(当全屏点击时，我将取消播放器静音。

我怎么能把一个"；静音"；从VideoList变为Player？在我的CCD_ 6中；取消静音"；按钮(也按预期工作：

这就是我目前拥有的

VideoItem.jsx

import React, { useRef, useState, useEffect } from "react"
import { findDOMNode } from "react-dom"
import screenfull from "screenfull"
import VideoPlayer from "./VideoPlayer"
const VideoList = (videos) => {
const ref = useRef()
const toggleFullScreen = () => {
screenfull.request(findDOMNode(ref.current))
}
const unMute = () => {
console.log("Should pass Mute state to player", muted)
}
return (
<>
<VideoPlayer
ref={ref}
mute={muted}
videoURL={videoUrl}
/>
<a
href="#"
onClick={e => {
e.preventDefault()
unMute()
toggleFullScreen()
}}
>
Show Fullscreen
</a>
)
}

播放器.jsx

import React, { forwardRef, useState, useEffect } from "react"
import ReactPlayer from "react-player"
const VideoPlayer = forwardRef((props, ref, mute) => {
let [muteState, setMuteState] = useState(true)
return (
<>
<i className={`fal fa-volume-${muteState ? "up" : "mute"}`}
onClick={() => {
setMuteState(!muteState)
}}
/>
<ReactPlayer
ref={ref}
muted={muteState}
loop={true}
playing={true}
url={props.videoURL}
/>
</>
)
}

谢谢！

当您试图从父级设置状态时，这通常是一个指标，表明您应该向上移动状态，并使子级由父级控制：

const VideoList = (videos) => {
const player = useRef();
const [muted, setMuted] = useState(true);
const [fullscreen, setFullscreen] = useState(false);
const handleToggleMute = () => setMuted(current => !current);
const handleFullscreen = event => {
event.preventDefault();
setMuted(false);
setFullscreen(true);
};
return (
<>
<VideoPlayer
ref={ref}
muted={muted}
fullscreen={fullscreen}
videoURL={videoUrl}
onToggleMute={handleToggleMute}
/>
<a href="#" onClick={handleFullscreen}>Show Fullscreen</a>
)
}

此外，我将useEffect与另一状态fullscreen一起使用以避免必须转发视频播放器的ref。

const VideoPlayer = ({videoURL, muted, fullscreen, onToggleMute}) => {
const playerRef = useRef();
useEffect(() => {
if (fullscreen) {
const videoElem = playerRef.current.getInternalPlayer();
screenfull.request(videoElem);
}
}, [fullscreen]);
return (
<>
<i 
className={`fal fa-volume-${muted ? "up" : "mute"}`}
onClick={onToggleMute}
/>
<ReactPlayer
ref={playerRef}
muted={muted}
loop={true}
playing={true}
url={videoURL}
/>
</>
)
}
