vue-router provides two forms of parameter passing styles: traditional
style ( ?k0=v0&k1=v1 ), Restful style ( / :key).query
params
traditional style
Example URL: http://127.0.0.1:5173/user?userid=123&username=张三
Using the traditional style, src/router/index.js
no adjustments needed, the content is as follows:
import {
createRouter, createWebHashHistory } from 'vue-router'
import Main from '../views/Main.vue'
import User from '../views/User.vue'
import NotFound from '../views/NotFound.vue'
const routes = [
{
path: '/',
name: 'Main',
component: Main
},
{
path: '/user',
name: 'User',
component: User,
},
{
path: '/:path(.*)', component: NotFound },
]
const router = createRouter({
history: createWebHashHistory(),
routes
})
export default router
Configure routing parameters
// App.vue
<template>
<router-link to="/user?userid=123&username=张三">go User Page</router-link>
<router-link :to="{path:'/user', query:{username:'张三', userid:123}}">go User Page</router-link>
// 推荐
<router-link :to="{name:'User', query:{username:'张三', userid:123}}">go User Page</router-link>
<router-view></router-view>
</template>
User.vue
Get parameters in
// 组合式
<script setup>
import {
useRoute } from 'vue-router'
const route = useRoute()
const userid = route.query.userid
const username = route.query.username
</script>
// 选项式
<script>
export default {
data() {
return {
userid: '',
username: ''
}
},
mounted() {
this.userid = this.$route.query.userid
this.username = this.$route.query.username
},
}
</script>
Restful style parameter passing
Example URL: http://127.0.0.1:5173/user/123/张三
Modify src/router/index.js
as follows:
import {
createRouter, createWebHashHistory } from 'vue-router'
import Main from '../views/Main.vue'
import User from '../views/User.vue'
import NotFound from '../views/NotFound.vue'
const routes = [
{
path: '/',
name: 'Main',
component: Main
},
{
path: '/user/:userid/:username',
name: 'User',
component: User,
},
{
path: '/:path(.*)', component: NotFound },
]
const router = createRouter({
history: createWebHashHistory(),
routes
})
export default router
Configure routing parameters
// App.vue
<template>
<router-link to="/user/123/张三">go User Page</router-link>
// 下面的方式不可用
// [Vue Router warn]: Path "/user" was passed with params but they will be ignored. Use a named route alongside
// params instead.
<router-link :to="{path:'/user', params:{username:'张三', userid:123}}">go User Page</router-link>
// 推荐
<router-link :to="{name:'User', params:{username:'张三', userid:123}}">go User Page</router-link>
<router-view></router-view>
</template>
User.vue
Get parameters in
// 组合式
<script setup>
import {
useRoute } from 'vue-router'
const route = useRoute()
const userid = route.params.userid
const username = route.params.username
</script>
// 选项式
<script>
export default {
data() {
return {
userid: '',
username: ''
}
},
mounted() {
this.userid = this.$route.params.userid
this.username = this.$route.params.username
},
}
</script>
The above two methods of passing parameters can basically complete the project after learning
expand
The parameters are mapped to by mapping props
. By default, only params
the parameters in the mapping are implemented as follows:
Modifysrc/router/index.js
const routes = [
{
path: '/',
name: 'Main',
component: Main
},
{
path: '/user/:userid/:username',
name: 'User',
component: User,
// 添加
props: ture
},
{
path: '/:path(.*)', component: NotFound },
]
After the mapping switch is turned on, it needs props
to be received in the jump page at the same time
// 组合式
<script setup>
import {
useRoute } from 'vue-router'
defineProps({
userid: String,
username: String
})
</script>
//选项式
<script>
export default {
props: {
userid: String,
username: String
}
}
</script>
You can also query
map the parameters in , which is a little more troublesome, as follows:
// src/router/index.js
const routes = [
{
path: '/',
name: 'Main',
component: Main
},
{
path: '/user',
name: 'User',
component: User,
// 添加
// props: ture
// 这里我是直接将query 给映射过去了,当然如果你只有一个参数的话,你也可以
// props: route => ({ userid: route.query.userid })
props: route => ({
query: route.query })
},
{
path: '/:path(.*)', component: NotFound },
The values are as follows:
// User.vue
<template>
<h2>User Page</h2>
<div>{
{ query.userid }}</div>
<div>{
{ query.username }}</div>
</template>
// 组合式
<script setup>
defineProps({
query: {
type: Object,
default() {
return {
}
}
}
})
</script>
// 选项式
<script>
export default {
props: {
query: {
type: Object,
default() {
return {
};
}
}
}
}
</script>
In addition to the above-mentioned method of passing parameters, you can also use the methods of 共享全局变量
, Cookie
, localStorage
and, interested friends can try
