初学vue，遇到很多不明白的方，记录一下。

先看router/index.js

import Vue from 'vue'
import Router from 'vue-router'
import Login from '@/components/Login'
import Dashboard from '@/components/Dashboard'
import ArticleList from '@/components/article/List'
import ArticleEdit from '@/components/article/Edit'
Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      redirect: {
        name: ''
      }
    }
    ,
    {
      path: '/login',
      name: 'Login',
      component: Login
    },
    {
      path: '/dashboard',
      name: 'Dashboard',
      component: Dashboard,
      children:[
        {
          path: '/article',
          name: 'Article',
          component: ArticleList,
          children:[
            {
              path: 'add',
              name: 'ArticleAdd',
              component: ArticleEdit,
            },
            {
              path: 'index',
              name: 'ArticleIndex',
              component: ArticleList,
            }
          ]
        }
      ]
    }

  ]
})

当你访问的时候，发现

http://localhost:8001/#/login

http://localhost:8001/#/dashboard

都正常，但是访问时：

http://localhost:8001/#/article/index

http://localhost:8001/#/article/add

都是显示的文章列表，也就是article/index中的内容，无法显示article/add中的表单。

检查元素，发现没有加载过来。检查，子路由前面并没有加/,所以这没有问题，排除。

其实这是article这一级没有component，有了componnet,并且需要在这个component理要有,修改下：

children:[
        {
          path: '/article',
          name: 'Article',
          component: Article,
          children:[
            {
              path: 'add',
              name: 'ArticleAdd',
              component: ArticleEdit,
            },
            {
              path: 'index',
              name: 'ArticleIndex',
              component: ArticleList,
            }
          ]
        }
      ]

Article.vue如下：

<template>
  <div>
    <router-view></router-view>
  </div>
</template>

<script>
    export default {
        name: "Articleview"
    }
</script>

<style scoped>

</style>

这样就可以实现嵌套了。
