Vue路由嵌套

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/:color',
      name: 'HelloWorld',
      component: HelloWorld,
      //子路由
      children:[{
        path: '/:color',
        component: HelloWorld,
      }]
    }
  ]
})
