前言:
中實現預設進來頁面,某個div全屏,並監聽退出全屏的次數,當退出全屏次數達到5的時候跳轉到別的頁面。
實現步驟:
1、頁面上在你想要的容器上加上id = ‘con_lf_top_div',再給他加個動態class名,加上提示和點選進入全屏按鈕
<template> <el-card shadow="never" class="examining" v-loading.fullscreen.lock="loading" id="con_lf_top_div" :class="{'isScreen':!fullscreen}" > <p style="color:red;">*溫馨提示:請在全屏下進行考試,退出全屏5次以後將禁止考試</p> <el-button v-if="fullscreen" @click="screen();screen()" sLRvAWmxtyle="position: absolute;top: 0px;right: 0;">全屏</el-button> ...其他內容
2、部分,全屏後的部分需要單獨加樣式
.isScreen{ height:100vh!important; overflow-y: auto; }
3、部分
data:
fullscreen:false,//是否全屏 goCount:0 //退出第幾次
mounted初始化呼叫
mounted() { this.initScreen() }
methods定義方法:
//初始化全屏方法 initScreen(){ this.goCount = 0 this.screen() //開啟全屏 window.addEventListener('keydown',function(event) { //禁掉F11的全屏的預設事件,不會禁止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.$message.info('當前是退出第'+this.goCount+'次') console.log('當前是退出第'+this.goCount+'次') this.fullscreen = true if(this.goCount == 5){ this.goBack() } } }) },
完整原始碼:
1、頁面: <el-card id="con_lf_top_div" :clLRvAWmxass="{'isLRvAWmxScreen':!fullscreen}" > <p style="color:red;">*溫馨提示:請在全屏下進行考試,退出全屏5次以後將禁止考試</p> <el-button v-if="fullscreen" @click="screen();screen()" style="position: absolute;top: 0px;right: 0;">全屏</el-button> ... 2、data: fullscreen:false,//是否全屏 goCount:0 //退出第幾次 3、mounted: this.initScreen() 4、methods: //初始化全屏方法 initScreen(){ http://www.cppcns.comthis.goCount = 0 this.screen() //開啟全屏 window.addEventListener('keydown',function(event) { //禁掉F11的全屏的預設事件,不會禁止F11的退出全屏 const e = event || window.event if (e && e.keyCode === 122) { e.preventDefault() } }) document.addEventListener('fullscreenchange',v => { if(this.fullscreen == true){ this.fullscreen = false }else{ this.goCount++ // 注意這裡的事件都會觸發兩次 console.log('當前是退出第'+this.goCount+'次') this.fullscreen = true if(this.goCount == 5){ this.goBack() } } }) },//全屏方法 screen(){ //設定後就是id==con_lf_top_div 的容器全屏 let element = document.getElementById('con_lf_top_div'); if (this.fullscreen) { if (document.exitFullscreen) { document.exitFullscreen(); } else if (document.webkitCancelFullScreen) { document.webkitCancelFullScreen(); } else if (http://www.cppcns.comdocument.mozCancelFullScreen) { document.mozCancelFullScreen(); } else if (document.msExitFullscreen) { document.msExitFullscreen(); } } else { if (element.requestFullscreen) { element.requestFullscreen(); } else if (element.webkitRequestFullScreen) { element.webkitRequestFullScreen(); } else if (element.mozRequestFullScreen) { element.mozRequestFullScreen(); } else if (element.msRequestFullscreen) { // IE11 element.msRequestFullscreen(); } } this.fullscreen = !this.fullscreen; },//退出全屏方法 goBack(){ //111111111111111111111111111111111111111 this.$message.error('您已退出全屏5次,當前考試已經結束') this.$router.go(-1) },
