对象数组中的组属性-Javascript

Question

更新：

我可以通过以下方式获取ID和必填项的内容：

let group_to_values = salesRes.reduce（（obj，elem）=> {让subprops = {item：elem.item，itemQuantity：elem.itemQuantity，itemPrice：elem.itemPrice}; obj [elem.id] = obj [ elem.id] || []; obj [elem.id] .push（subprops）; return obj;}，{}）;让输出= Object.keys（group_to_values）.map（key  => {return {id：key，items：group_to_values [key]}; }）;

如何在输出中包括其余其他道具，例如status，totalAmount等？

原始帖子：

我正在得到这个对象数组：

[{
    id: 1,
    status: "completed",
    totalAmount: 3100,
    date: "2019-06-29T14:27:55.000Z",
    email: "test@test.com",
    customerNote: "test note",
    phone: "300-0000000",
    item: "item1",
    itemQuantity: 3,
    itemPrice: 1000
}, {
    id: 1,
    status: "completed",
    totalAmount: 3100,
    date: "2019-06-29T14:27:55.000Z",
    email: "test@test.com",
    customerNote: "test note",
    phone: "300-0000000",
    item: "item2",
    itemQuantity: 1,
    itemPrice: 100
}, {
    id: 3,
    status: "completed",
    totalAmount: 4500,
    date: "2019-07-16T15:19:59.000Z",
    email: "test2@tes.com",
    customerNote: "Please deliver asap",
    phone: "00000000000",
    item: "item3",
    itemQuantity: 1,
    itemPrice: 2000
}, {
    id: 3,
    status: "completed",
    totalAmount: 4500,
    date: "2019-07-16T15:19:59.000Z",
    email: "test2@tes.com",
    customerNote: "Please deliver asap",
    phone: "00000000000",
    item: "item4",
    itemQuantity: 1,
    itemPrice: 2500
}, {
    id: 2,
    status: "completed",
    totalAmount: 140,
    date: "2019-06-29T15:22:03.000Z",
    email: "test@test.com",
    customerNote: "note",
    phone: "300-0000000",
    item: "item1",
    itemQuantity: 1,
    itemPrice: 50
}, {
    id: 2,
    status: "completed",
    totalAmount: 140,
    date: "2019-06-29T15:22:03.000Z",
    email: "test@test.com",
    customerNote: "note",
    phone: "300-0000000",
    item: "item3",
    itemQuantity: 1,
    itemPrice: 90
}]

我正在尝试将项目（item，itemQuantity和itemPrice）分组到子数组中。我该如何转换：

 [{
    id: 1,
    status: "completed",
    totalAmount: 3100,
    date: "2019-06-29T14:27:55.000Z",
    email: "test@test.com",
    customerNote: "test note",
    phone: "300-0000000",
    items: [{
        item: "item1",
        itemQuantity: 3,
        itemPrice: 1000
    }, {
        item: "item2",
        itemQuantity: 1,
        itemPrice: 100
    }]
}, {
    id: 3,
    status: "completed",
    totalAmount: 4500,
    date: "2019-07-16T15:19:59.000Z",
    email: "test2@tes.com",
    customerNote: "Please deliver asap",
    phone: "00000000000",
    items: [{
        item: "item3",
        itemQuantity: 1,
        itemPrice: 2000
    }, {
        item: "item4",
        itemQuantity: 1,
        itemPrice: 2500
    }]
}, {
    id: 2,
    status: "completed",
    totalAmount: 140,
    date: "2019-06-29T15:22:03.000Z",
    email: "test@test.com",
    customerNote: "note",
    phone: "300-0000000",
    items: [{
        item: "item1",
        itemQuantity: 1,
        itemPrice: 50
    }, {
        item: "item3",
        itemQuantity: 1,
        itemPrice: 90
    }]
}];
