vue版本根据当前路由匹配到根父节点并且激活
页面布局
我的项目是有两种布局方式的， 一种是左侧布局，还有一种是顶部+左侧的布局，在这里主要讲顶部+左侧布局 因为左侧的相对简单，会自行匹配
业务场景
当页面刷新的时候，要回到原来的页面，并且要激活正确的一级和二级菜单
首先 在data中创建数据
data() { return { menus: [],//菜单数据是id pid 加上children格式的 parentNodes: [] //最终调用函数返回的结果集 } },
获取当前页面路由的id和pid
let path = this.$route.path let id = this.$route.meta.id let pid = this.$route.meta.pid
最后返回的时候 当前路由的根节点的节点数据

测试代码： 因为是 cdn引入的没有看出效果
