1.  第一步安装依赖 `cnpm install --save screenfull`
2.  封装组件 components下创建文件夹Screenfull 下创建文件index.vue

//index.vue中代码
    			<template>
    			  <div>
    			    <svg-icon :icon-class="isFullscreen?'exit-fullscreen':'fullscreen'" @click="click" />
    			  </div>
    			</template>
    			
    			<script>
    			import screenfull from 'screenfull'
    			
    			export default {
    			  name: 'Screenfull',
    			  data() {
    			    return {
    			      isFullscreen: false
    			    }
    			  },
    			  mounted() {
    			    this.init()
    			  },
    			  beforeDestroy() {
    			    this.destroy()
    			  },
    			  methods: {
    			    click() {
    			      if (!screenfull.enabled) {
    			        this.$message({
    			          message: 'you browser can not work',
    			          type: 'warning'
    			        })
    			        return false
    			      }
    			      screenfull.toggle()
    			    },
    			    change() {
    			      this.isFullscreen = screenfull.isFullscreen
    			    },
    			    init() {
    			      if (screenfull.enabled) {
    			        screenfull.on('change', this.change)
    			      }
    			    },
    			    destroy() {
    			      if (screenfull.enabled) {
    			        screenfull.off('change', this.change)
    			      }
    			    }
    			  }
    			}
    			</script>
    			
    			<style scoped>
    			.screenfull-svg {
    			  display: inline-block;
    			  cursor: pointer;
    			  fill: #5a5e66;;
    			  width: 20px;
    			  height: 20px;
    			  vertical-align: 10px;
    			}
    			</style>

3.页面中使用

//script中首先引入
    import Screenfull from '@/components/Screenfull'
     components: {
        Screenfull
      },
    //template页面中使用
    <screenfull id="screenfull"  class="right-menu-item hover-effect" />

！注意exit-fullscreen/fullscreen svg图片放入icons下的svg文件夹下可自定义
