vue.js中如何将一个组件的卡数据绑定到另一个组件卡？

Question

我有两个组件，一个是显示卡，负责将数据显示到来自后端（DisplayNotes.vue）的卡中，另一个是通过打开弹出窗口（updateNotes.vue）更新现有数据卡，如果用户单击任何卡片都会打开一个弹出窗口，负责编辑数据，但在我的情况下，如果用户单击任何卡片，它应该打开弹出卡片（UpdateNotes.vue）以及现有数据，我的问题是如何从中获取数据卡片变成弹出式卡片 [这里我点击第四张卡片，当我点击第四张卡片时，内容应该绑定到弹出式卡片] 1 ，请帮我把数据放到弹出式卡片中

DisplayNotes.vue

<template>
<div class="carddisplay-section" >
    <div  v-for="note in notes" :key="note.id"  id="blur" class="container note">
        <div @click="toggle(note.id)" class="card-content">
            <h5>{{note.title}}</h5>
            <p>{{note.body}}</p>
        </div>
        <div class="import-icons">
            <icons class="imported-icons note-icons" />
            <button v-if="flag" class="card-button" type="button" @click="handlesubmit();Togglebtn();">Close</button>
        </div>
    </div>
    <div id="popup">
        <UpdateNotes :cardId="clickedCard"/>
    </div>
</div>
</template>

<script>
import service from '../service/User'
import icons from './icons'
import UpdateNotes from './UpdateNotes.vue'
export default {
    name: 'DisplayNotes',
    components: {
        icons,UpdateNotes
    },
    data() {
        return {
            flag: true,
            notes: [{
                id: 1,
                title: 'Fundoo',
                body: 'unlimited notes..'
            }, ],
           clickedCard:'',
        }
    },
    methods: {
        Togglebtn() {
            this.flag = !this.flag;
        },
        async handlesubmit() {
            service.userDisplayNotes().then(response => {
                this.notes.push(...response.data);
            })
        },
        toggle(id){
            var blur=document.getElementById('blur');
            blur.classList.toggle('active');
             this.clickedCard = id;

            var popup=document.getElementById('popup');
            popup.classList.toggle('active');

        },
    }
}

当您在弹出窗口中传递卡片的 id 时，类似地在弹出窗口中传递当前单击的卡片的数据。

UpdateNotes.vue

<template>

<div v-if="flag==false" class="update">
    <form class="update-note" @submit.prevent autocomplete="off">
        <input name="title" v-model="title" placeholder="Title" />
        <textarea name="content" v-model="body" style="resize: none" placeholder="Take a note..." rows="3"></textarea>
        <div class="btm-icons">
            <icons />
            <button id="btn-section" type="submit" @click="handlesubmit();flip();">Close</button>
        </div>
    </form>
</div>

</template>

<script>
import icons from './icons.vue'
import service from '../service/User'
export default {
    components: {
        icons
    },
    props: ['cardId', 'cardContent'],
    data() {
        return {
            title: '',
            body: '',
            flag: false,
        }
    },
    created () {
        this.title = this.cardContent.title;
        this.body = this.cardContent.body;
    },
    methods: {
        flip() {
            this.flag = !this.flag;
        },
        async handlesubmit() {
            let userData = {
                id: this.cardId,
                title: this.title,
                body: this.body
            }
            service.userUpdateNotes(userData).then(response => {
                alert("Note updated  successfully");
                return response;
