如何獲取javascript物件中兄弟鍵的值？-有解無憂

我有以下物件，并想獲取月份等于“2022-04-01”的“payroll_run_items”，所以…… 就像鍵值 Foo 的兄弟鍵的值。

{
  "payrollRuns": [
    {
      "company": {
        "id": 1,
        "name": "Example Ltd.",
        "country": "Germany",
        "city": "Munich",
        "zip": "80801",
        "street": "Max-Strasse",
        "house_number": "3",
        "vat": "DE12434",
        "customer_number": "1",
        "fee_offer": "59.00",
        "is_active": true
      },
      "month": "2022-06-01",
      "amount": "733.00",
      "line_items": 1,
      "payroll_run_items": []
    },
    {
      "company": {
        "id": 1,
        "name": "Example Ltd.",
        "country": "Germany",
        "city": "Munich",
        "zip": "80801",
        "street": "Max-Strasse",
        "house_number": "3",
        "vat": "DE12434",
        "customer_number": "1",
        "fee_offer": "59.00",
        "is_active": true
      },
      "month": "2022-04-01",
      "amount": "7570.02",
      "line_items": 2,
      "payroll_run_items": [
        "{amount: \"3749.00\", id: 68, month: {…}, offer: {…},…}",
        "{amount: \"3821.02\", id: 73, month: {…}, offer: {…},…}"
      ]
    }
  ],
  "setPayrollRuns": "? bound dispatchSetState() {}"
}

到目前為止，我想出的只是獲取所有密鑰，但是我現在如何檢查“2022-04-01”并將“payroll_run_items”分配給變數？

const payrollLineItems = () => (
        Object.keys(props.payrollRuns)
    )

find月份匹配條件的物件，并提取您想要的屬性值。

const data={payrollRuns:[{company:{id:1,name:"Example Ltd.",country:"Germany",city:"Munich",zip:"80801",street:"Max-Strasse",house_number:"3",vat:"DE12434",customer_number:"1",fee_offer:"59.00",is_active:!0},month:"2022-06-01",amount:"733.00",line_items:1,payroll_run_items:[]},{company:{id:1,name:"Example Ltd.",country:"Germany",city:"Munich",zip:"80801",street:"Max-Strasse",house_number:"3",vat:"DE12434",customer_number:"1",fee_offer:"59.00",is_active:!0},month:"2022-04-01",amount:"7570.02",line_items:2,payroll_run_items:['{amount: "3749.00", id: 68, month: {…}, offer: {…},…}','{amount: "3821.02", id: 73, month: {…}, offer: {…},…}']}]};

const out = data.payrollRuns.find(obj => {
  return obj.month === '2022-04-01';
}).payroll_run_items;

console.log(out);
