侧边栏(ios设备)使用video标签全屏后 只能听见声音 不能看见画面 关闭侧边栏的时候 会看到全屏的video在页面后方 补充： 1、只有在ios设备+侧边栏的情况下有问题 2、ios设备+企业微信应用形式打开 没有问题 3、安卓设备+侧边栏 的情况下也没有问题 4、代码 function isFullscreen() {   return (     document.fullscreenElement ||     document.webkitFullscreenElement ||     document.mozFullScreenElement ||     document.msFullscreenElement   ) } function requestFullscreen(elem) {   if (elem.requestFullscreen) {     elem.requestFullscreen()   } else if (elem.mozRequestFullScreen) {     /* Firefox */     elem.mozRequestFullScreen()   } else if (elem.webkitRequestFullscreen) {     /* Chrome, Safari & Opera */     elem.webkitRequestFullscreen()   } else if (elem.msRequestFullscreen) {     /* IE/Edge */     elem.msRequestFullscreen()   } } class FullscreenVideo extends React.Component {   static propTypes = {     src: PropTypes.string,   }   static defaultProps = {     src: '',   }   componentDidMount() {     document.addEventListener('fullscreenchange', this.fsHandler)     document.addEventListener('webkitfullscreenchange', this.fsHandler)     document.addEventListener('mozfullscreenchange', this.fsHandler)     document.addEventListener('MSFullscreenChange', this.fsHandler)   }   componentWillUnmount() {     document.removeEventListener('fullscreenchange', this.fsHandler)     document.removeEventListener('webkitfullscreenchange', this.fsHandler)     document.removeEventListener('mozfullscreenchange', this.fsHandler)     document.removeEventListener('MSFullscreenChange', this.fsHandler)   }   fsHandler = () => {     if (!isFullscreen() && this.videoRef) {       this.videoRef.pause()     }   }   play = () => {     this.videoRef.play()     requestFullscreen(this.videoRef)   }   render() {     const {src} = this.props     return (       <video         ref={videoRef => (this.videoRef = videoRef)}         height="0"         width="100%"         webkitPlayinline         playinline       >         <source src={src} />       </video>     )   } } export default FullscreenVideo
