干了一个很蠢的事，在使用ElementUI中的el-menu组件时，需要读取路由并跳转，发现嵌套路由不加载组件的问题，例如
import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '../views/Home.vue'
import Testa from '../views/Test2.vue'
import Testb from '../views/Test3.vue'
import Testc from '../views/Test4.vue'
Vue.use(VueRouter)
const routes = [
{
path: '/',
name: 'Home',
component: Home,
},
{
path: '/home',
name: 'Home',
component: Home
},
{
path: '/about',
name: 'About',
// route level code-splitting
// this generates a separate chunk (about.[hash].js) for this route
// which is lazy-loaded when the route is visited.
component: () => import(/* webpackChunkName: "about" */ '../views/About.vue')
},
{
path: '/test',
name: 'test',
component: () => import('../views/Test1.vue'),
children:[
{path: '/test/testa', name: 'testa',component: Testa},
{path: '/test/testb', name: 'testb',component: Testb},
{path: '/test/testc', name: 'testc',component: Testc},
]
}
]
const router = new VueRouter({
routes
})
export default router
组件正确读取$router中的参数，并且router属性也是打开的，会正常跳转url，但是没有加载组件，发现是我没有在Test1组件中，给出路由出口<router-view/>,由此 问题解决，这可真蠢，记录一下
