在vue中使用screenfull 依赖,实现全屏组件方式

npm install --save screenfull

<template>
  <div class="full-screen-wrapper" @click="handleFullscreen">
    <el-tooltip
      effect="dark"
      :content="isFullscreen ? '退出全屏' : '全屏'"
      placement="bottom"
    >
      <i
        :class="[
          'icon',
          !isFullscreen
            ? 'vue-dsn-icon-fullscreen'
            : 'vue-dsn-icon-tuichuquanping',
        ]"
      />
    </el-tooltip>
