本文介绍: 【用router.push跳转,用params带参数age=666】这个方法router->index.ts。// 用router.push跳转,用query带参数name=lin。// 用router.push跳转,用params带参数age=666。,是以前可以用,现在变不一样了吗?:vue3目标页面要拿到上一页面带过来的参数,不能用。// 用routerlink跳转带参数id=1。其他2中方法router->index.ts

indexrouter
在这里插入图片描述

<!-- 路由跳转 -->
<template>
	<div>
		<div class="title-sub flex">
			<div>1、用router-link跳转带参数id=1:</div><router-link to="./link?id=1"><button>点我跳转</button></router-link>
		</div>
		<div class="title-sub flex">
			<div>2、用router.push跳转,用query带参数name=lin:</div>
			<button @click="queryLink">点我跳转</button>
		</div>
		<div class="title-sub pl-60">
			注:用router.push的query参数,router->index.ts为【path: '/link',】即可,router.push可用name也可用path
		</div>
		<div class="title-sub flex">
			<div>3、用router.push跳转,用params带参数age=666:</div>
			<button @click="paramsLink">点我跳转</button>
		</div>
		<div class="title-sub pl-60">
			注:用router.push的params参数,需要在router->index.ts里更改path: '/link/:age?',name:'link'】,(ps:age后面的?代表这个参数可传可不传),router.push要用name
		</div>
	</div>
</template>

<script lang="ts" setup>
	import { useRouter } from 'vue-router';
	const router = useRouter();
	// query
	function queryLink(){
		router.push({path:'/link',query:{name:'lin'}})
	}
	// params
	function paramsLink(){
		router.push({name:'link',params:{age:'666'}})
	}
</script>

index-link

		<div class="title-sub flex" v-if="linkData">
			<div>用router-link跳转拿到参数:{{linkData}}</div>

	.index-title{

【用router.push跳转,用params带参数age=666】这个方法的router->index.ts

import { RouteRecordRaw, createRouter, createWebHistory } from 'vue-router'
 
// 静态路由
const routes: Array<RouteRecordRaw> = [
	{
	    path: '/link/:age?',
		name:'link',
	    component: () => import('../views/home/index-link.vue')
	}
]
 
// 路由对象
const router = createRouter({
    history: createWebHistory(),
    routes
})
 
export default router

其他2中方法的router->index.ts

{
   path: '/link',
   component: () => import('../views/home/index-link.vue')
}

ps:vue3目标页面要拿到上一页面带过来的参数,不能用route.query,要用route.currentRoute.value.query或者route.currentRoute.value.params,是以前可以用,现在变不一样了吗?有大佬知道告知下。谢谢!
