路由的query參數（傳參）

路由組件不會在組件里面放自己組件標簽。

案例使用嵌套組件的，但是在Message組件下新增了組件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'

//關閉Vue的生產提示
Vue.config.productionTip = false
//應用插件
Vue.use(VueRouter)

//創建vm
new Vue({
    el:'#app',
    render: h => h(App),
    router:router
})
