通过监听窗口的大小变化可以实现横屏自动全屏播放，但全屏播放后，竖屏就没法触发onWindowResize监听了。请问如何实现竖屏时退出全屏并回到竖屏模式？该用什么思路来解决？

我想要的效果就像《微信游戏直播》的小程序一样（我的是点播）。请各位大神指点迷津！

代码基于uni-app写的，不要看着奇怪啊！

wxml:

<video id="myVideo" src="video.mp4" enable-danmu danmu-btn controls poster="https://.../poster.png"></video>

js:

onShow() {             wx.onWindowResize((res) => {                 console.log('onWindowResize:', res);                 this.isLandscape = res.deviceOrientation === 'landscape';                                   if (this.isLandscape){                     if (!this.inPlay){                         this.videoContext.play();                     }                     this.fullScreen();                 }else{                     this.exitFullScreen();                 }                               });         },   onReady: function(res) {             this.videoContext = wx.createVideoContext('myVideo')         },

pages.json:

// 针对视频播放页面设置了支持横屏 {     "pageOrientation": "auto" }
