前言： vue中实现默认进来页面，某个div全屏，并监听退出全屏的次数，当退出全屏次数达到5的时候跳转到别的页面。
实现步骤：1、页面上在你想要的容器上加上id = ‘con_lf_top_div'，再给他加个动态class名，加上提示和点击进入全屏按钮 
<template> <el-card shadow="never" class="examining" v-loading.fullscreen.lock="loading" id="con_lf_top_div" :class="{'isScreen':!fullscreen}" > <p style="color:red;">*温馨提示：请在全屏下进行考试，退出全屏5次以后将禁止考试</p> <el-button v-if="fullscreen" @click="screen();screen()" style="position: absolute;top: 0px;right: 0;">全屏</el-button> ...其他内容 2、css部分，全屏后的部分需要单独加样式 .isScreen{ height:100vh!important; overflow-y: auto; }3、js部分 data: fullscreen:false,//是否全屏goCount:0 //退出第几次 mounted初始化调用 mounted() { this.initScreen()}methods定义方法： 
//初始化全屏方法 initScreen(){ this.goCount = 0 this.screen() //打开全屏 window.addEventListener('keydown', function(event) { //禁掉F11的全屏的默认事件,不会禁止F11的退出全屏 const e = event || window.event if (e && e.keyCode === 122) { e.preventDefault() } }) document.addEventListener('fullscreenchange', v => { if(this.fullscreen == true){ this.fullscreen = false }else{ this.goCount++ // this.$message.info('当前是退出第'+this.goCount+'次') console.log('当前是退出第'+this.goCount+'次') this.fullscreen = true if(this.goCount == 5){ this.goBack() } } }) },
完整源码：1、页面：<el-card id="con_lf_top_div" :class="{'isScreen':!fullscreen}" > <p style="color:red;">*温馨提示：请在全屏下进行考试，退出全屏5次以后将禁止考试</p> <el-button v-if="fullscreen" @click="screen();screen()" style="position: absolute;top: 0px;right: 0;">全屏</el-button> ... 2、data:fullscreen:false,//是否全屏goCount:0 //退出第几次 3、mounted:this.initScreen() 4、methods: //初始化全屏方法initScreen(){ this.goCount = 0 this.screen() //打开全屏 window.addEventListener('keydown', function(event) { //禁掉F11的全屏的默认事件,不会禁止F11的退出全屏 const e = event || window.event if (e && e.keyCode === 122) { e.preventDefault() } }) document.addEventListener('fullscreenchange', v => { if(this.fullscreen == true){ this.fullscreen = false }else{ this.goCount++ // 注意这里的事件都会触发两次 console.log('当前是退出第'+this.goCount+'次') this.fullscreen = true if(this.goCount == 5){ this.goBack() } } })},//全屏方法screen(){ //设置后就是id==con_lf_top_div 的容器全屏 let element = document.getElementById('con_lf_top_div'); if (this.fullscreen) { if (document.exitFullscreen) { document.exitFullscreen(); } else if (document.webkitCancelFullScreen) { document.webkitCancelFullScreen(); } else if (document.mozCancelFullScreen) { document.mozCancelFullScreen(); } else if (document.msExitFullscreen) { document.msExitFullscreen(); } } else { if (element.requestFullscreen) { element.requestFullscreen(); } else if (element.webkitRequestFullScreen) { element.webkitRequestFullScreen(); } else if (element.mozRequestFullScreen) { element.mozRequestFullScreen(); } else if (element.msRequestFullscreen) { // IE11 element.msRequestFullscreen(); } } this.fullscreen = !this.fullscreen; },//退出全屏方法goBack(){ //111111111111111111111111111111111111111 this.$message.error('您已退出全屏5次，当前考试已经结束') this.$router.go(-1) },
