vue多级路由怎么实现
实现多级路由的基本配置
在Vue Router中,多级路由通过嵌套的children属性实现。每个路由配置对象可以包含children数组,用于定义子路由。子路由的路径会基于父路由的路径进行拼接。
const routes = [
{
path: '/parent',
component: ParentComponent,
children: [
{
path: 'child',
component: ChildComponent,
children: [
{
path: 'grandchild',
component: GrandchildComponent
}
]
}
]
}
]
路由视图的嵌套
父级组件中需要使用<router-view>作为子路由的出口。例如在ParentComponent中:
<template>
<div>
<h2>Parent Component</h2>
<router-view></router-view>
</div>
</template>
动态路由参数传递
多级路由支持动态参数传递,参数会继承到子路由:

{
path: '/user/:id',
component: User,
children: [
{
path: 'profile',
component: UserProfile
}
]
}
命名路由的使用
为多级路由设置名称可以简化导航:
{
path: '/settings',
component: Settings,
children: [
{
path: 'account',
name: 'settings.account',
component: AccountSettings
}
]
}
路由懒加载优化
使用动态导入实现路由组件的懒加载,提升应用性能:

{
path: '/admin',
component: () => import('./Admin.vue'),
children: [
{
path: 'dashboard',
component: () => import('./AdminDashboard.vue')
}
]
}
路由守卫的应用
可以为多级路由配置全局或局部守卫:
{
path: '/protected',
component: ProtectedLayout,
meta: { requiresAuth: true },
children: [
{
path: 'dashboard',
component: Dashboard
}
]
}
路由重定向配置
在多级路由中设置重定向:
{
path: '/products',
component: Products,
children: [
{
path: '',
redirect: 'list'
},
{
path: 'list',
component: ProductList
}
]
}
