一、树形菜单功能实现
1、要确定静态树形菜单节点的样式排版
2、要获取树形节点的数据
????????this.axios.post
3、通过拿到的数据，渲染树形节点
? ? ? ? v-for渲染节点
????????定义渲染节点的变量
【LeftNav.vue】?

二、书籍列表查询
1、el-table 列表组件
2、利用axios调用后台的文章查询接口 ——> created ? （无传参）?
3、el-pagination 列表组件
????????size-change ? ? ? ?页大小改变调用事件
? ? ? ? current-change ? ?页面改变调用的事件
?4、优化
? ? ? ? 将调用后台的文章查询接口的代码进行封装，为了复用
5、el-form ?查询的筛选条件 ? ?（传参）
this.doSeach? 公用的查询方法
this.search? 带领查询条件的方法
