路由组件不会在组件里面放自己组件标签。
案例使用嵌套组件的,但是在Message组件下新增了组件Detail.vue
index.html
//引入bootstrap.css
<link rel="stylesheet" href="<%= BASE_URL %>css/bootstrp.css">
main.js
//引入Vue import Vue from 'vue' //引入App import App from './App.vue' //引入VueRouter import VueRouter from 'vue-router' //引入路由器 import router from './router' //关闭Vue的生产提示 Vue.config.productionTip = false //应用插件 Vue.use(VueRouter) //创建vm new Vue({ el:'#app', render: h => h(App), router:router })
