获取键和值以及使用reduce函数javascript的键和对象

Question

我有下面的数据从我的API调用，我正在使用减少函数设置数据根据我的要求。但无法生产，请查看下面的代码和需要的输出。还要检查我正在尝试的功能，并建议我创建响应的方法。

API回应:

let cmpRecords =  {
"status": "success",
"message": "Record Fetched Successfully",
"data": [
{
"_id": "6098ff60a8e9ee2c7c116d6e",
"record": {
"creatorName": "ABC",
"modifierName": ""
},
"is_deleted": "0"
},
{
"_id": "6098ff60a8e9ee2c7c116d6e",
"record": {
"creatorName": "ABC",
"modifierName": ""
},
"is_deleted": "0"
},
{
"_id": "6098ff60a8e9ee2c7c116d6z",
"record": {
"creatorName": "XYZ",
"modifierName": ""
},
"is_deleted": "0"
},
...
]
}

要求输出::

{
"status": "success",
"message": "Record Fetched Successfully",
"data": [
{
"name": "ABC",
"record": [
{
"_id": "6098ff60a8e9ee2c7c116d6e",
"record": {
"creatorName": "ABC",
"modifierName": ""
},
"is_deleted": "0"
},
{
"_id": "6098ff60a8e9ee2c7c116d6e",
"record": {
"creatorName": "ABC",
"modifierName": ""
},
"is_deleted": "0"
}
]
},
{
"name": "XYZ",
"record": [
{
"_id": "6098ff60a8e9ee2c7c116d6z",
"record": {
"creatorName": "XYZ",
"modifierName": ""
},
"is_deleted": "0"
}
]
}
]
}

因为我想分开同一用户的记录，键和值&

group = cmpRecords.reduce((r, a) => {
let name = a.record.creatorName;
let record = a;
r[name] = [...r[name] || [], record];
return r;
}, {});

以

回应

"data": [
"ABC":[
{
"_id": "6098ff60a8e9ee2c7c116d6e",
"record": {
"creatorName": "ABC",
"modifierName": ""
},
"is_deleted": "0"
},
...
]
]

我尝试了其他方法，但没有得到要求的响应。

您可以使用Array.reduce()按名称对记录进行分组，这里的输出应该是您需要的:

const cmpRecords =  { "status": "success", "message": "Record Fetched Successfully", "data": [ { "_id": "6098ff60a8e9ee2c7c116d6e", "record": { "creatorName": "ABC", "modifierName": "" }, "is_deleted": "0" }, { "_id": "6098ff60a8e9ee2c7c116d6e", "record": { "creatorName": "ABC", "modifierName": "" }, "is_deleted": "0" }, { "_id": "6098ff60a8e9ee2c7c116d6z", "record": { "creatorName": "XYZ", "modifierName": "" }, "is_deleted": "0" }, ] }
const output = {
...cmpRecords,
data: Object.values(cmpRecords.data.reduce((acc, cur) => { 
acc[cur.record.creatorName] = acc[cur.record.creatorName] || { name: cur.record.creatorName, record: [] };
acc[cur.record.creatorName].record.push(cur);
return acc;
}, {}))
}
console.log('Output:', output)
