javascript - À propos de la boucle d'un tableau en js

Question

Le prototype en js est comme ça

<code>cms.addNav([
        { id: 1, pid: 0, node: '运行环境', url: '?s=Admin-Index-Right' },
        { id: 2, pid: 0, node: '系统', url: '' },
        { id: 3, pid: 2, node: '网络配置', url: '?s=Admin-Admin-Config' },
        { id: 4, pid: 2, node: '导航管理', url: '?s=Admin-Nav-Show' },
        { id: 6, pid: 2, node: '缓存管理', url: '?s=Admin-Cache-Show' },
        { id: 7, pid: 2, node: '标签管理', url: '?s=Admin-Tag-Show' },
        { id: 8, pid: 2, node: '模板管理', url: '?s=Admin-Tpl-Show' },
    ], 0, 'id', 'pid', 'node', 'url');</code>

Je souhaite obtenir ce qui suit via ajax

<code>        { id: 1, pid: 0, node: '运行环境', url: '?s=Admin-Index-Right' },
        { id: 2, pid: 0, node: '系统', url: '' },
        { id: 3, pid: 2, node: '网络配置', url: '?s=Admin-Admin-Config' },
        { id: 4, pid: 2, node: '导航管理', url: '?s=Admin-Nav-Show' },
        { id: 6, pid: 2, node: '缓存管理', url: '?s=Admin-Cache-Show' },
        { id: 7, pid: 2, node: '标签管理', url: '?s=Admin-Tag-Show' },
        { id: 8, pid: 2, node: '模板管理', url: '?s=Admin-Tpl-Show' },</code>

La sortie des données JSON est comme ça

<code>[

        "id": 1,
        "name": "sys",
        "title": "系统设置",

Comment dois-je l'écrire ?

Utiliser la carte pour la conversion des données

<code>let newArr = arr.map(({id, pid, title, name}) => {
    return {id, pid, node: title, url: name};
})</code>
