【问题描述】:
我有这个样本数据:
const data = [
{
id: 1,
title: 'Sports',
menus: [
{
id: 2,
title: 'Basketball',
menus: [
{
id: 3,
title: 'NBA',
},
{
id: 4,
title: 'NCAA',
},
{
id: 5,
title: 'G-League',
},
],
},
],
},
{
id: 100,
title: 'Names',
menus: [],
},
];
我想把所有的menus键改成children,所以结果是:
const result = [
{
id: 1,
title: 'Sports',
children: [
{
id: 2,
title: 'Basketball',
children: [
{
id: 3,
title: 'NBA',
},
{
id: 4,
title: 'NCAA',
},
{
id: 5,
title: 'G-League',
},
],
},
],
},
{
id: 100,
title: 'Names',
children: [],
},
];
我正在尝试使用此代码:
const replacer = { menus: 'children' };
const transform = useCallback(
(obj) => {
if (obj && Object.getPrototypeOf(obj) === Object.prototype) {
return Object.fromEntries(Object.entries(obj).map(([k, v]) => [replacer[k] || k, transform(v)]));
}
return obj;
},
[replacer]
);
但它只更改第一级的键。我怎样才能让它发挥作用?
