1、项目中使用的是sreenfull插件,执行命令安装

npm install --save screenfull

2、安装好后,引入项目,用一个按钮进行控制即可,按钮方法如下:

toggleFullscreen() {
    if (!screenfull.enabled) {
      this.$message({
        message: 'you browser can not work',
        type: 'warning'
      })
      return false
    }
    screenfull.toggle()
}

试了一下可以全屏,我用的chrome,IE9以下不要考虑

3、第一步完成之后就是怎么监听到全屏的变化,因为如果是通过Esc键退出全屏,此时是没办法监听到的。经过一番查找,解决办法如下:

<script>
import screenfull from 'screenfull'
export default {
  data () {
      return {
        isFullscreen: false
      }
   },
  methods: {
    /**
     * 全屏事件
     */
    screenfull() {
      if (!screenfull.enabled) {
        this.$message({
          message: 'Your browser does not work',
          type: 'warning'
        })
        return false
      }
      screenfull.toggle()
      this.isFullscreen = true
    },
    /**
     * 是否全屏并按键ESC键的方法
     */
    checkFull() {
      var isFull = document.fullscreenEnabled || window.fullScreen || document.webkitIsFullScreen || document.msFullscreenEnabled
      // to fix : false || undefined == undefined
      if (isFull === undefined) {
          isFull = false
      }
      return isFull
    }
  },
  mounted() {
      window.onresize = () => {
            // 全屏下监控是否按键了ESC
            if (!this.checkFull()) {
              // 全屏下按键esc后要执行的动作
              this.isFullscreen = false
            }
          }
       }
}
</script>
