VUE+elementui面包屑实现动态路由详解

我的路由：constrouterMap=[{path:'/',redirect:'dashboard',component:Layout,name:'Dashboard',children:[{path:'dashboa

我的路由：

const routerMap = [
 {
 path: '/',
 redirect: 'dashboard',
 component: Layout,
 name:'Dashboard',
 children: [
 {
 path: 'dashboard',
 component: () => import('@/view/dashboard'),
 name: 'Dashboard',
 meta: { title: 'dashboard', icon: 'dashboard', noCache: true }
 }
 ]
 },{
 path:'/test',
 component:Layout,
 redirect: '/test/index',
 name:'Test',
 meta:{title:'test',icon:'lock'},
 children:[
 {
 path:'index',
 component:()=>import('@/view/test'),
 name:'test',
 meta:{title:'test', icon: 'example', noCache: true }
 },{
 path:'example',
 component:()=>import('@/view/test/example'),
 name:'example',
 meta:{title:'example',icon:'404'}
 }
 ]
 }
]

面包屑代码：

<template>
 <div class="navbar clearfix">
 <el-breadcrumb class="breadcrumb-container" separator-class="el-icon-arrow-right">
 <el-breadcrumb-item v-for="item in levelList":key="item.path" :to="item.path">{{item.meta.title}}</el-breadcrumb-item>
 </el-breadcrumb>
 </div>
</template>

<script>
 export default {
 name: 'Navbar',
 data() {
 return {
 levelList: []
 }
 },
 watch: {
 $route() {
 this.getBreadcrumb()
 }
 },
 created(){
 this.getBreadcrumb()
 },
 methods:{
 getBreadcrumb() {
 let matched = this.$route.matched.filter(item => item.name)
 const first = matched[0];
 if (first && first.name.trim().toLocaleLowerCase() !== 'Dashboard'.toLocaleLowerCase()) {
 matched = [{ path: '/dashboard', meta: { title: 'dashboard' }}].concat(matched)
 }
 this.levelList = matched
 }
 }
 }
</script>

原理：通过监听当前路由的变化，动态更新面包屑的内容。
