javascript - 如何获取特定点击的卡片 ID 并将该 ID 传递给 vue.js 中的后端 API？

问题描述

我有两个组件 DisplayNotes.vue 负责在仪表板上显示注释，响应来自后端（显示为卡片），当我单击更多图标时，下一个组件是此图标中的 icons.vue（负责图标） （3个点图标）[见选项img ] 1它应该打开下拉选项，如果我单击DeleteNote选项我想根据该ID获取特定的点击卡ID，我必须将该ID传递给我的API-url，我我试图通过使用道具来做，但它没有达到正确的 URl（id 与 #7% 之类的差异..）[检查这里] 2.我无法弄清楚我在哪里出错了，请帮我解决这个问题

user.js

   userTrashNote(data){
        return axios.userTrash(`/deleteNote/${data.id}`,data);
    }

解决方案

 userTrashNote(data){
        return axios.userTrash("/deleteNote/${data.id}",data);
    }

这是错误的，使用反引号

userTrashNote(data){
    return axios.userTrash(`/deleteNote/${data.id}`,data);
}

好的，现在这不碍事了，你为什么要在焦点上更改卡 ID？要么创建一个新组件并将其传递给它，note以便它可以自行处理，要么在删除时传递 id。

<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" :cardId="note.id" />
            <button v-if="flag" class="card-button" type="button" @click="handlesubmit();Togglebtn();">Close</button>
        </div>
    </div>
    <div id="popup">
        <UpdateNotes :cardId="clickedCard" :cardContent="cardContent" />
    </div>
</div>
</template>

看看我现在如何传递<icons class="imported-icons note-icons" :cardId="note.id" />note.id 而不是依靠方法来设置它。
