Vue路由-使用children属性实现路由

在登录父组件中嵌套两个字组件 account1和account2，点击按钮后，可以在父组件中切换子组件

第一步，创建父组件，父组件中包含两个子组件
- 注意：需要在父组件中设置占位符，用来放置子组件

<template id="tmp1">
    <div>
        <h1>这是登录父组件</h1>
        <router-link to="/login/account1">子组件account1</router-link>
        <router-link to="/login/account2">子组件account2</router-link>
        <router-view></router-view>
    </div>
</template>

var login = Vue.extend({
    template: '#tmp1'
})

第二步，创建路由规则
- 子组件的路由规则通过childer属性创建
- 子组件的路由规则中path属性值不要加 /

var routeObj = new VueRouter({
    routes: [
        {
            path: '/login',
            component: login,
            children: [
                {path: 'account1', component: account1},
                {path: 'account2', component: account2},
            ]
        }
    ]
})
