Vue全屏效果 Vue使用screenfull实现全屏效果

npm install --save screenfull

import screenfull from 'screenfull'

<template>
 <span @click='clickFullscreen'>全屏</span>
</template>
 
<script>
 import screenfull from 'screenfull'
 export default{
 name: 'screenfull',
 data(){
 return {
 isFullscreen: false
 }
 },
 methods:{
 clickFullscreen(){
 if (!screenfull.isEnabled) {
 this.$message({
 message: 'you browser can not work',
 type: 'warning'
 })
 return false
 }
 screenfull.toggle()
 }
 }
 }
</script>

// 全屏事件 兼容
clickFullscreen() {
 let element = document.documentElement;
 if (this.isFullscreen) {
  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.isFullscreen= !this.isFullscreen;
}
