1、安裝路由
npm i vue-router2、編寫需要展示的路由
在src目錄下創(chuàng)建pages文件夾，里面創(chuàng)建兩個(gè)vue文件命名為student.vue,person.vue
分別編寫兩個(gè)vue文件
student.vue和person.vue
<template>
學(xué)生
</template>
<script setup>
</script>
<style scoped lang="less">
</style><template>
人類
</template>
<script setup>
</script>
<style scoped lang="less">
</style>3、配置路由
在src目錄下配置router.js文件
import { createRouter,createWebHistory } from "vue-router";
const router=createRouter({
history:createWebHistory(),
routes:[
{
component:()=>import('../pages/person.vue'),
name:'person',
path:'/person'
},
{
component:()=>import('../pages/student.vue'),
name:'student',
path:'/student'
},
{
//實(shí)現(xiàn)路由重定向，當(dāng)進(jìn)入網(wǎng)頁(yè)時(shí)，路由自動(dòng)跳轉(zhuǎn)到/student路由
redirect:'/student',
path:'/'
}
]
})
export default router3、使用路由
在main.js中使用路由
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
createApp(App).use(router).mount('#app')在app.vue中進(jìn)行路由展示，使用router-link進(jìn)行路由跳轉(zhuǎn)，to代表跳轉(zhuǎn)到哪個(gè)路由
<template>
<router-view></router-view>
<hr>
<div>
<router-link to="/student">到student路由</router-link>
<br>
<router-link to="/person">到person路由</router-link>
</div>
</template>
<script setup>
</script>
<style scoped>
</style>
效果如下圖所示，點(diǎn)擊（到student路由）或（到person路由）會(huì)進(jìn)行路由跳轉(zhuǎn)
?4、編程式路由
聲明式路由通過(guò)router-link進(jìn)行路由跳轉(zhuǎn)，編程式路由通過(guò)函數(shù)實(shí)現(xiàn)
修改app.vue，vue3使用的是組合式API，需要引入
要引入useRouter,useRoute,還要
const router=useRouter()
const route=useRoute()
<template>
<router-view></router-view>
<hr>
<div>
<button @click="toStudent">到student路由</button>
<br>
<button @click="toPerson">到person路由</button>
</div>
</template>
<script setup>
import {useRouter,useRoute} from 'vue-router'
const router=useRouter()
const route=useRoute()
const toStudent=()=>{
router.push('student')
}
const toPerson=()=>{
router.push('person')
}
</script>
<style scoped>
</style>
通過(guò)router.push進(jìn)行路由跳轉(zhuǎn)
路由之間用router路由器，當(dāng)前路由使用toute路由
結(jié)果如下圖所示，實(shí)現(xiàn)編程式路由跳轉(zhuǎn)
?如果在配置路由時(shí)沒(méi)有設(shè)置別名，需要通過(guò)router.push配置對(duì)象進(jìn)行跳轉(zhuǎn)
const toStudent=()=>{
router.push({
path:'/student'
})
}
const toPerson=()=>{
router.push({
path:'/person'
})
}5、路由傳參
5、1query參數(shù)傳遞
向student路由傳遞id,name
const toStudent=()=>{
router.push({
path:'/student',
query:{
id:1,
name:'張三'
}
})
}student路由接收query參數(shù)
<template>
學(xué)生組件
<div>{{data.query}}</div>
</template>
<script setup>
import { reactive } from 'vue';
import {useRouter,useRoute} from 'vue-router'
const route=useRoute()
let data=reactive({
query: route.query
})
</script>效果如下圖所示
5、2傳遞params參數(shù)?
假設(shè)向person路由傳遞params參數(shù)，要在路由配置時(shí)進(jìn)行修改
params傳參需要使用name進(jìn)行指定路由
const toPerson=()=>{
router.push({
name:'person',
params:{
keyword:2
}
})
}同時(shí)在路由配置需要修改，假設(shè)傳遞的是keyword，
需要在path使用占位符加關(guān)鍵字
？表示可傳可不傳
{
component:()=>import('../pages/person.vue'),
name:'person',
path:'/person/:keyword?'
},在person.vue中接收params參數(shù)
<template>
人類組件
<div>{{data.params.keyword}}</div>
</template>
<script setup>
import { reactive } from 'vue';
import {useRouter,useRoute} from 'vue-router'
const route=useRoute()
let data=reactive({
params: route.params
})
</script>效果如下所示
6、子路由配置
給student路由添加子組件(stu1，stu2組件)
?
子組件的path不帶 /??
{
component:()=>import('../pages/student.vue'),
name:'student',
path:'/student',
children:[
{
path:'stu1',
name:'stu1',
component:()=>import('../pages/stu1.vue')
},
{
path:'stu2',
name:'stu2',
component:()=>import('../pages/stu2.vue')
},
{
path:'',
component:()=>import('../pages/stu1.vue')
}
]
}編寫stu1組件
<template>
stu1
</template>
<script setup>
</script>
<style scoped lang="less">
</style>編寫stu2組件
<template>
stu2
</template>
<script setup>
</script>
<style scoped lang="less">
</style>?在student組件進(jìn)行子組件展示
<template>
學(xué)生組件
<div>{{data.query}}</div>
子組件展示
<router-view></router-view>
<router-link to="/student/stu1">到stu1</router-link>
<router-link to="/student/stu2">到stu2</router-link>
</template>
<script setup>
import { reactive } from 'vue';
import {useRouter,useRoute} from 'vue-router'
const route=useRoute()
let data=reactive({
query: route.query
})
</script>通過(guò)使用router-link進(jìn)行路由跳轉(zhuǎn)，也可以通過(guò)編程式路由跳轉(zhuǎn)
to="/student/stu1"? 需要使用完整路徑進(jìn)行跳轉(zhuǎn)
