Vue3.0路由跳转携带参数的示例详解

//引入API---useRouter
import { useRouter } from 'vue-router'
......
//定义router变量
const router =useRouter()
const methodClick=(data)=>{
let paramValue=data.deviceCode
//路由跳转，携带参数
router.push('/equipment/operation?deviceCode='+paramValue)

用router.push跳转页面：
例：
// 字符串
router.push('home')
// 对象
router.push({ path: 'home' })
// 命名的路由
router.push({ name: 'user', params: { userId: '123' }})
// 带查询参数，变成 /register?userId=123
router.push({ path: 'register', query: { userId: '123' }})

import { useRoute } from 'vue-router'
......
//在接收页面定义变量route，获取传过来的变量
const route = useRouter()
onMounted(() => {
	if (route.currentRoute.value.query.deviceCode) {
		state.codeDevice2 = route.currentRoute.value.query.deviceCode
	}
})

例：
//首先在setup中定义
const route = useRoute()
//query
let userId=route.query.userId;
//params
let userId=route.params.userId;

const userId = '123'
router.push({ name: 'user', params: { userId }}) // -> /user/123
router.push({ path: `/user/${userId}` }) // -> /user/123
// 这里的 params 不生效
router.push({ path: '/user', params: { userId }}) // -> /user
