我想遍歷一個物件陣列并獲取所有物件的所有資料但只有我只得到最后一個物件的資料我不知道為什么它會跳過第一個物件，請任何人都可以幫助我
這是我的陣列

如您所見，我只得到最后一個物件的陣列
對于誰好奇我的代碼是什么樣子的
async getLogByTPE() {
let result;
const data = await this.tpeModel
.aggregate([
{
$lookup: {
from: 'logs',
localField: 'terminalId',
foreignField: 'terminalId',
as: 'resultData',
},
},
// { $unwind: '$resultData' },
// {
// $project: {
// uniqueID: '$logs.currenuniqueIDcyCode',
// terminalId: '$logs.terminalId',
// transactionAmount: '$logs.transactionAmount',
// currencyCode: '$logs.currencyCode',
// transactionDate: '$logs.transactionDate',
// transactionTime: '$logs.transactionTime',
// transactionType: '$logs.transactionType',
// cardPAN_PCI: '$logs.cardPAN_PCI',
// onlineRetrievalReferenceNumber:
// '$logs.onlineRetrievalReferenceNumber',
// outcome: '$logs.outcome',
// encryptionKeyKCV: '$logs.encryptionKeyKCV',
// transactionEncrypted: '$logs.transactionEncrypted',
// },
// },
])
.then((ok) => {
//start of test
// for (let i = 0; i <= ok.length; i ) {
// console.log('ok', ok[i].resultData[i]);
// data1 = JSON.stringify(ok[i]);
// }
//end of test
// console.log('OOOKKKK', ok);
ok.forEach((item) => {
console.log('item', item);
console.log('----------------------------------------------------');
//console.log('resultData', item.resultData);
result = item.resultData;
// result = item['resultData'].forEach((sub) => {
// console.log('sub', sub);
// return sub;
// });
});
});
// let subitemresult;
// let result = data.forEach((item) => {
// console.log('item', item);
// console.log(
// 'item.resultData',
// item.resultData.forEach((subitem) => {
// console.log('subitem', subitem);
// }),
// );
// });
// console.log('data', data);
// console.log('result', JSON.stringify(result));
console.log(result);
return result;
}
ok => 我的物件陣列
item => 陣列內的物件
resultData => 我想獲取的資料
不幸的是我只有最后一個物件的 resultData，如上所示
uj5u.com熱心網友回復：
在回圈中存盤資料的結果變數在每次迭代時都會被覆寫，因此當您回傳時，只存盤最后一個值。快速修復可以在結果宣告中分配一個空陣列
let result: any = [];
然后在回圈內你可以推送到陣列結果。將此更改result = item.resultData;為
result.push(item.resultData);
