通过本节Vue2嵌套路由教程,你将系统性掌握:
Vue2嵌套路由是什么?这是Vue Router提供的高级特性,允许在路由中定义子路由,实现多层级的页面结构,也是构建复杂应用的核心技术。
💡 学习建议:嵌套路由是Vue Router的高级特性,建议先掌握基础路由和动态路由,再学习嵌套结构。重点理解父子路由的渲染机制。
嵌套路由通过children属性定义子路由:
// 🎉 嵌套路由配置示例
const routes = [
{
path: '/admin',
component: AdminLayout,
children: [
// 空路径表示默认子路由
{ path: '', component: AdminDashboard },
// 用户管理模块
{
path: 'users',
component: UserManagement,
children: [
{ path: '', component: UserList },
{ path: 'create', component: UserCreate },
{ path: ':id', component: UserDetail },
{ path: ':id/edit', component: UserEdit }
]
},
// 内容管理模块
{
path: 'content',
component: ContentManagement,
children: [
{ path: '', redirect: 'articles' },
{
path: 'articles',
component: ArticleManagement,
children: [
{ path: '', component: ArticleList },
{ path: 'create', component: ArticleCreate },
{ path: ':id', component: ArticleDetail },
{ path: ':id/edit', component: ArticleEdit }
]
},
{
path: 'categories',
component: CategoryManagement,
children: [
{ path: '', component: CategoryList },
{ path: 'create', component: CategoryCreate },
{ path: ':id/edit', component: CategoryEdit }
]
}
]
},
// 系统设置模块
{
path: 'settings',
component: SystemSettings,
children: [
{ path: '', component: GeneralSettings },
{ path: 'security', component: SecuritySettings },
{ path: 'notifications', component: NotificationSettings }
]
}
]
}
]

}通过本节Vue2嵌套路由教程的学习,你已经掌握:
A: 嵌套路由允许在父路由中定义子路由,形成层级结构。父组件包含router-view来渲染子组件,而普通路由是平级关系。嵌套路由更适合复杂的应用结构。
A: 子路由的路径默认是相对于父路由的。如果子路由路径以/开头,则是绝对路径。建议使用相对路径保持路由结构的清晰性。
A: 可以通过路由参数、查询参数、props传递数据。也可以使用Vuex等状态管理工具在父子组件间共享数据。
A: 将子路由的path设置为空字符串('')即可设置为默认子路由。当访问父路由时,会自动渲染默认子路由组件。
A: 嵌套路由本身不会显著影响性能,但深层嵌套可能增加组件层级。建议合理设计路由结构,避免过度嵌套,并使用路由懒加载优化性能。
// 问题:子路由配置了但不显示
// 解决:确保父组件包含router-view
// ❌ 错误示例
const ParentComponent = {
template: `
<div>
<h1>父组件</h1>
<!-- 缺少router-view -->
</div>
`
}
// ✅ 正确示例
const ParentComponent = {
template: `
<div>
<h1>父组件</h1>
<router-view></router-view> <!-- 必须包含router-view -->
</div>
`
}// 问题:子路由路径配置不正确
// 解决:注意相对路径和绝对路径的区别
// ❌ 错误示例
const routes = [
{
path: '/admin',
component: Admin,
children: [
{ path: '/users', component: Users } // 绝对路径,会匹配/users而不是/admin/users
]
}
]
// ✅ 正确示例
const routes = [
{
path: '/admin',
component: Admin,
children: [
{ path: 'users', component: Users } // 相对路径,匹配/admin/users
]
}
]// 问题:默认子路由不生效
// 解决:正确配置空路径和重定向
// ❌ 错误示例
const routes = [
{
path: '/admin',
component: Admin,
children: [
{ path: 'dashboard', component: Dashboard } // 没有默认路由
]
}
]
// ✅ 正确示例
const routes = [
{
path: '/admin',
component: Admin,
children: [
{ path: '', component: Dashboard }, // 默认子路由
{ path: 'users', component: Users }
]
}
]
// 或者使用重定向
const routes = [
{
path: '/admin',
component: Admin,
children: [
{ path: '', redirect: 'dashboard' },
{ path: 'dashboard', component: Dashboard },
{ path: 'users', component: Users }
]
}
