Lodash从另一个对象中追加对象而不进行替换

Question

如何在不替换的情况下从另一个对象向对象追加值？

我正在尝试将一个值从ObjectA附加到ObjectB，作为子对象的名称。

我是ObjectA.

​

可以看出，ObjectA有4个子对象，每个子对象都与一个uid关联。

我是ObjectB

​

所以我试着把每个孩子的uid从ObjectA映射到ObjectB。

这就是理想代码的样子

Object.keys(ObjectA).forEach(
    (key) => _.assign(ObjectB, {'Product 07': true})
)

我试图将每个ObjectB迭代注入到源占位符ES6字符串内插，但是它会失败，就像这样。

Object.keys(ObjectA).forEach(
    (key) => _.assign(ObjectB, {`${basketObject[key].uid}`: true})
)

Source(JSON)

请使用此代码使用_.mapValues将对象对象转换为数组对象，以从对象名称生成uid。

var ObjectA = _.mapValues(data, (val, index) => {
    return { ...val, index }
})

Answer 1

它应该能工作

_.mapValues(ObjectA, (val) => {
    ObjectB[val.uid] = true;
})

Answer 2

您可以使用reduce将对象映射到另一个对象；

var objects = [ // Your objects, this is just dummy data
    { uuid: 'Product 01', approved: true },
    { uuid: 'Product 02', approved: true },
    { uuid: 'Product 03', approved: true }
]

var items = objects.reduce(function (prev, current) {
    prev[current.uuid] = current.approved;
    return prev;
}, {});
