vue2的组件通讯方式有：
vue3记录
1、父组件向子组件传递参数（通过符号:），子组件通过defineProps接收：
//1、父组件中引入子组件并通过":"向子组件传值：
<Child info="我是父组件，给你钱" :money="money"></Child>//2、子组件中使用"defineProps"接收：
<template><div class="son"><h1>我是子组件:曹植</h1><p>{{props.info}}</p><p>{{props.money}}</p><!--props可以省略前面的名字---><p>{{info}}</p><p>{{money}}</p><button @click="updateProps">修改props数据</button></div>
</template><script setup>
//需要使用到defineProps方法去接受父组件传递过来的数据
//defineProps是Vue3提供方法,不需要引入直接使用
let props = defineProps(['info','money']); //数组|对象写法都可以
//按钮点击的回调
const updateProps = ()=>{props.money+=10; //props:只读的console.log(props)
}
