16.vue项目浏览器全屏screenfull

1.安装screenfull

这里使用vue ui 可视化界面

2.导入screenfull

在commonHeader.vue组件中导入
代码如下，有基础的直接看方法就可以

<template>
  <header>
    <div>
      <i class="el-icon-s-fold" v-show="!isCollapse" @click="collapseMenu"></i>
      <i class="el-icon-s-unfold" v-show="isCollapse" @click="collapseMenu"></i>

    const sessionLang = JSON.parse(sessionStorage.getItem('currentLang'))
    console.log(sessionLang)
    if (sessionLang !== null) {

    // 控制是否是全屏还是非全屏
    screen() {

      screenfull.toggle()
      this.isFullscreen = !screenfull.isFullscreen
      // console.log(screenfull.isFullscreen)
