路由当中的嵌套

路由当中的嵌套，需要用到router对象身上的children属性，这个属性是一个数组，里面传入子组件的路由规则
例：
<!DOCTYPE html>
<html lang="zh-CN">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <script src="js/vue.js"></script>
    <script src="js/vue-router-3.0.1.js"></script>
</head>

<body>
    <div id="app">
        <router-link to="/account">account</router-link>
        <router-view></router-view>
    </div>
    <template id="tmpl">
        <div>
            <h1>这是Account组件</h1>
            <router-link to='/account/login'>登陆</router-link>
            <router-link to='/account/register'>注册</router-link>
            <!-- 子组件的模板占位符 -->
            <router-view></router-view>
        </div>
    </template>
    <script>
        var account = {
            template: '#tmpl'
        }
        var login = {
            template: '<h3>登陆</h3>'
        }
        var register = {
            template: '<h3>注册</h3>'
        }

        var router = new VueRouter({
            routes: [
                {
                    path: '/account', 
                    component: account,
                    // 子组件的路由匹配放在children属性当中，注意，子路由的路径不要带 /
                    children: [
                       {path: 'login', component: login},
                       {path: 'register', component: register}
                    ]  
                }
            ]
        })
        var vm = new Vue({
            el: '#app',
            data: {},
            methods: {},
            router
        });
    </script>
</body>
