12.Vue嵌套路由(三层)

Vue嵌套路由：
实现效果(路由三层嵌套，点击一级tab显示二级tab效果，二级tab点击切换对应内容,不在tab区域里的内容，切换时不重复渲染)：

Demo访问时路径：http://IP:端口/#/routers/

1.建立案例文件夹 page/routers/

1 routers/index.vue

  .rlink {    padding: 5px;    margin: 5px;    margin-bottom: 10px;    display: inline-block;    text-decoration: none;    color: blue;
  }  .rlink.active {    color: red;    text-decoration: underline;
  }

1-1-1 routers/home/index.vue

1-1-2 routers/home/tab/gj.vue、gn.vue、zx.vue

gj.vue：gn.vue :zx.vue：

1-2 routers/news/index.vue

1-2-1 routers/news/tab/gj.vue、gn.vue、zx.vue

gj.vue：gn.vue：zx.vue：

1-3-1 routers/yl/index.vue

1-3-2 routers/yl/tab/jd.vue、mx.vue、zx.vue

jd.vue：mx.vue：zx.vue：

2.路由配置规则(router/index.js)

....
  省略导入路由、使用路由代码...
....// 嵌套路由的使用：第一层import Rindex from '../page/routers/index'// 嵌套路由的使用：第二层import Rhome from '../page/routers/home/index'// 嵌套路由的使用：第三层import Rhomezx from '../page/routers/home/tab/zx'import Rhomegj from '../page/routers/home/tab/gj'import Rhomegn from '../page/routers/home/tab/gn'import Rnews from '../page/routers/news/index'import Rnewszx from '../page/routers/news/tab/zx'import Rnewsgj from '../page/routers/news/tab/gj'import Rnewsgn from '../page/routers/news/tab/gn'import Ryl from '../page/routers/yl/index'import Rylzx from '../page/routers/yl/tab/zx'import Rylmx from '../page/routers/yl/tab/mx'import Ryljd from '../page/routers/yl/tab/jd'// 路由规则配置：export default new Router({  routes : [

            ]
