vue导航实现
Vue 导航实现方法
使用 Vue Router 实现基础导航
安装 Vue Router 依赖：
npm install vue-router在项目中配置路由：
import { createRouter, createWebHistory } from 'vue-router'
import Home from './views/Home.vue'
import About from './views/About.vue'
const routes = [
{ path: '/', component: Home },
{ path: '/about', component: About }
]
const router = createRouter({
history: createWebHistory(),
routes
})
export default router在主文件中引入并使用路由：
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
const app = createApp(App)
app.use(router)
app.mount('#app')导航菜单实现
在组件中使用 <router-link> 创建导航链接：
<template>
<nav>
<router-link to="/">Home</router-link>
<router-link to="/about">About</router-link>
</nav>
<router-view/>
</template>动态路由实现
定义带参数的路由：
const routes = [
{ path: '/user/:id', component: User }
]在组件中访问路由参数：
import { useRoute } from 'vue-router'
export default {
setup() {
const route = useRoute()
const userId = computed(() => route.params.id)
return { userId }
}
}导航守卫
实现全局前置守卫：
router.beforeEach((to, from, next) => {
if (to.meta.requiresAuth && !isAuthenticated) {
next('/login')
} else {
next()
}
})实现路由独享守卫：
const routes = [
{
path: '/admin',
component: Admin,
beforeEnter: (to, from, next) => {
if (adminAccess) next()
else next('/')
}
}
]嵌套路由
定义嵌套路由结构：
const routes = [
{
path: '/user',
component: User,
children: [
{ path: 'profile', component: Profile },
{ path: 'posts', component: Posts }
]
}
]在父组件中添加 <router-view> 显示子路由：
<template>
<div>
<h2>User Page</h2>
<router-view/>
</div>
</template>编程式导航
在组件方法中使用编程式导航：
import { useRouter } from 'vue-router'
export default {
setup() {
const router = useRouter()
const goToAbout = () => {
router.push('/about')
}
const replaceToHome = () => {
router.replace('/')
}
return { goToAbout, replaceToHome }
}
}命名路由
定义命名路由：
const routes = [
{
path: '/user/:id',
name: 'user',
component: User
}
]使用命名路由进行导航：
router.push({ name: 'user', params: { id: 123 } })
