如何判斷 懶加載 是否真的 ‘懶加載’了----vue-router 單頁面應用中vue-router實現懶加載（按需加載）

import Vue from 'vue'

import Router from 'vue-router'

import LayOut from '@/views/LayOut'

import ElementUI from 'element-ui'

import 'element-ui/lib/theme-chalk/index.css'

// import page2 from '@/views/page2'

Vue.use(Router)

Vue.use(ElementUI)

 

export default new Router({

routes: [

{

path: '/',

name: 'LayOut',

component: LayOut,

children: [

{

path: '/page2',

name: 'page2',

// component: page2

component: (resolve) => require(['@/views/page2'], resolve)

}

]

}

]

})
