vue-router

/* jshint esversion: 6 */注webstrom中不添加改注释报es6错误提示
import Vue from 'vue';
import Router from 'vue-router';
import HelloWorld from '../components/HelloWorld';
import first from '../components/first';
import second from '../components/second';
import third from '../components/third';
Vue.use(Router);export default new Router({
  routes: [
    {
      path:"/HelloWorld",
      redirect:'/HelloWorld'
    },
    {
      path: '/',
      name: 'HelloWorld',//路由名称<router-link :to='{name:'helloWorld'}'>或者<router-link to:'./'也就是path>
      component: HelloWorld
    },
    {
      path:"/first",
      name:'a',
      component:first
    },
    {
      path:"/second",
      name:"second",
      component:second,
      children:[
        {
          path:"/second/third",//目录为http://localhost:8087/#/second/third；path:"/third"目录为http://localhost:8087/#/third
          name:"aa",
          component:third
        }
      ]
    }
  ]
});

且主要的router-link应该放入app.vue文件，
单个组件内部的子路由在该对应的组件内添加router-link
