js 实现全屏

news/2024/10/17 22:27:19/

全屏是否可用：Document.fullscreenEnabled
开启全屏：Document.requestFullScreen() 该方法返回 promise
退出全屏：Document.exitFullscreen() 让当前元素退出全屏模式，会有一个全屏栈
获取元素全屏状态：Document.mozFullScreenElement
全屏模式变化事件: fullscreenchange
参考博客

全屏方法需要用户手动操作的事件触发，如点击等

fullScreen() {let el = this.$refs.vbox; // 获取需要全屏的 dom/*if (el.requestFullscreen) {el.requestFullscreen();} else if (el.webkitRequestFullScreen) {el.webkitRequestFullScreen();} else if (el.mozRequestFullScreen) {el.mozRequestFullScreen();} else if (el.msRequestFullscreen) {el.msRequestFullscreen();}*/el.requestFullscreen||el.mozRequestFullScreen||el.webkitRequestFullscreen||el.msRequestFullScreen?el.requestFullscreen()||el.mozRequestFullScreen()|| el.webkitRequestFullscreen()||el.msRequestFullscreen():null;// 可以更新全屏的标志变量
}

这种方案虽然简单，但无法与其他组件内容配合，如抽屉等功能
此 api 在 iPhone 上不受支持

screenfull.js

简化写兼容性方法，浅封装
npm screenfull

useFullscreen

vueuse 提供的全屏功能

单页面应用中

可以有单独的全屏页面，全屏的同时因为是单页面可以兼顾其他组件。不会出现遮挡的情况
确定不能跳转时自动全屏
