我有以下物件
{
"object": "list",
"url": "/v1/prices",
"has_more": false,
"data": [
{
"id": "price_1KHlU72eZvKYlo2CblI51Z8e",
"object": "price",
"active": true,
"billing_scheme": "per_unit",
"created": 1642150211,
"currency": "usd",
"livemode": false,
"lookup_key": null,
"metadata": {},
"nickname": null,
"product": "prod_Kxgr3hZDfHnqu1",
"recurring": {
"aggregate_usage": null,
"interval": "month",
"interval_count": 1,
"usage_type": "licensed"
},
"tax_behavior": "unspecified",
"tiers_mode": null,
"transform_quantity": null,
"type": "recurring",
"unit_amount": 2,
"unit_amount_decimal": "2"
},
{...},
{...}
]
}
如何根據unit_amount屬性對object.data進行排序，并保留物件的初始值（url、has_more、...）？
我試過使用 Ramda，但它給了我一個新的物件，只是排序后的資料。
所以我需要對初始物件中的 object.data 進行排序，并在排序后回傳整個物件。

只是簡單的排序，例如
const obj = {
"object": "list",
"url": "/v1/prices",
"has_more": false,
"data": [
{"unit_amount": 2,},
{"unit_amount": 1,},
{"unit_amount": 3,},
{"unit_amount": 9,},
{"unit_amount": 5,},
]
};
const newObj = { ...obj, data: obj.data.sort((o1, o2) => o1.unit_amount - o2.unit_amount) };
console.log(newObj).as-console-wrapper {max-height: 100% !important; top: 0}uj5u.com熱心網友回復：
Javascript 中的物件對其屬性沒有固有的順序，而陣列有，所以我建議您提取資料陣列，對其進行排序，然后替換物件中未排序的版本。像這樣的東西（為了便于閱讀而簡化的物件）：
o = {
"object": "list",
"url": "/v1/prices",
"has_more": false,
"data": [
{
"id": "price_1KH",
"unit_amount": 12,
},
{
"id": "price_7QW",
"unit_amount": 3,
},
{
"id": "price_4DD",
"unit_amount": 7,
},
]
}
let data = o.data;
data.sort((x, y) => x.unit_amount - y.unit_amount);
o.data = data;
console.dir(o);
VM694:23
Object
data: Array(3)
0: {id: 'price_7QW', unit_amount: 3}
1: {id: 'price_4DD', unit_amount: 7}
2: {id: 'price_1KH', unit_amount: 12}
length: 3
[[Prototype]]: Array(0)
has_more: false
object: "list"
url: "/v1/prices"
[[Prototype]]: Object

Ramda 不會讓您輕松修改資料，但如果您想使用陣列的排序副本創建輸入的副本，使用鏡頭函式非常簡單，lensProp并且over：
const sortData = over (lensProp ('data'), sortBy (prop ('unit_amount')))
const obj = {object: "list", url: "/v1/prices", has_more: false, data: [{unit_amount: 2,}, {unit_amount: 1,}, {unit_amount: 3,}, {unit_amount: 9,}, {unit_amount: 5,} ]};
console .log (sortData (obj)).as-console-wrapper {max-height: 100% !important; top: 0}<script src="//cdnjs.cloudflare.com/ajax/libs/ramda/0.27.2/ramda.min.js"></script>
<script>const {over, lensProp, sortBy, prop} = R </script>在這里，我們從 Alexandr Belan 那里竊取了簡單的輸入格式。該答案已經有一些簡單的代碼。我認為這更簡單——而且它肯定更具宣告性——但除非我已經在我的應用程式中使用 Ramda，否則我不會打擾它。
