VueRouter-路由嵌套

        背景：

            在大的路由下面有时候需要一些字路由进行切换数据，那么这时候需要使用路由嵌套。

        方法：

            1、直接在父路由中添加`children`字路由，格式和父路由一样。
let router = new VueRouter({
            routes: [{
                    path: "/",
                    component: index,
                },
                {
                    path: "/our",
                    component: our,
                    children: [{
                        path: "",
                        component: our_msg
                    }, {
                        path: "msg",
                        component: our_msg
                    }, {
                        path: "setting",
                        component: our_setting
                    }]
                }
            ]
        })
            2、在父路由组件中要添加路由出口（<router-view></router-view>），否则无法渲染子组件。
        var our = Vue.extend({
            template: `
            <div>
                <h1>我们</h1>
                <ul class="nav nav-tabs">
                    <li role="presentation" class="active">
                        <router-link to="/our/msg">消息</router-link>
                    </li>
                    <li role="presentation">
                        <router-link to="/our/setting">设置</router-link>
                    </li>
                </ul>
                <div class="container">
                    <router-view></router-view>
                </div>
            </div>
            `
        })

　　整体代码：
