用到element tree组件，需要了解他的一些方法
<template>
<div>
<!-- default-expand-all 默认展开全部数据 -->
<!-- expand-on-click-node 只有点击箭头才会收缩节点 -->
<!-- check-on-click-node 点击文本选中 -->
<!-- show-checkbox 复选框 -->
<el-tree ref="tree" :data="list" default-expand-all :expand-on-click-node='false' check-on-click-node show-checkbox node-key="menuId" :props="defaultProps"></el-tree>
<el-button @click="getCheckedKeys">通过 key 获取</el-button>
