  </div>
</template>

 data() {
    return {
      fullscreen: false
    };
  },

 screen() {
      let element = document.documentElement;
      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;
    },

npm install --save screenfull

import screenfull from ‘screenfull'

<template>
     <div>
         <a-button type="primary" @click="screen">全屏</a-button>
     <div>
</template>

 data() {
    return {
      fullscreen: false
    };
  },

screen() {
      // 如果不允许进入全屏，发出不允许提示
      if (!screenfull.enabled) {
        this.$message("您的浏览器不能全屏");
        return false;
      }
      screenfull.toggle();
      this.$message.success("全屏啦");
    },
