实现功能：页面A 跳转到 页面B，携带参数

路由router.ts

import { createRouter, createWebHistory } from "vue-router";

const routes: RouteRecordRaw[] = [
 	{
		path: "/demo/a",
		name: "aa",
		component: () => import("@/views/demo/A.vue")
	},
	{
		path: "/demo/b",
		name: "bb",
		component: () => import("@/views/demo/B.vue")
	},
];

const router = createRouter({
	history: createWebHistory(),
	routes,
	strict: false,
	// 切换页面，滚动到最顶部
	scrollBehavior: () => ({ left: 0, top: 0 })
});

export default router;

A.vue

<template>
	<div>
		<button @click="fun">传递和接收参数</button>
	</div>
</template>

<script setup lang="ts">
import { useRouter } from "vue-router";
//路由对象，用来进行路由跳转
let router = useRouter();
const fun = () => {
	router.push({
		name: "bb",
		state: {
			data: "苹果"
		}
	});
};
</script>

B.vue

<template>
	<div>
		<div>{{ stateData }}</div>
	</div>
</template>

<script setup lang="ts">
//用来获取路由对象的数据
const stateData = history.state; //通过History API接收
console.log("接收的参数：", stateData);
</script>

效果：

A页面中单击按钮，在打开的B页面中看到的效果如下：
