import Vue from 'vue'
import Router from 'vue-router'
import Home from '@/pages/home/Home'
import City from '@/pages/city/City'
import Detail from '@/pages/detail/Detail'

Vue.use(Router)

export default new Router({
  routes: [{
    path: '/',
    name: 'Home',
    component: Home
  }, {
    path: '/city',
    name: 'City',
    component: City
  }, {
    path: '/detail/:id',
    name: 'Detail',
    component: Detail
  }],
  scrollBehavior (to, from, savedPosition) {
    return { x: 0, y: 0 }
  }
})

通过箭头函数加import 可以实现异步加载组件功能,可以实现性能优化

import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
export default new Router({
  mode: 'history',  
  routes: [
    {
      path: '/',
      name: 'Home',
      component: () => import('@/pages/home/Home')
    },
    {
      path: '/city',
      name: 'City',
      component: () => import('@/pages/city/City')
    },
    {
      path: '/detail/:id',
      name: 'Detail',
      component: () => import('@/pages/detail/Detail')
    }
  ],
  scrollBehavior (to, from, savedPosition) {
    return { x: 0,y:0}
  }
})
