vue中实现默认进来页面,某个p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。
1、页面上在你想要的容器上加上id = ‘con_lf_top_p',再给他加个动态class名,加上提示和点击进入全屏按钮

*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
全屏 ...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()
}
}
})
},


1、页面:*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
全屏 ... 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_p 的容器全屏 let element = document.getElementById('con_lf_top_p'); 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) },
