如何計算node.js中的值-有解無憂

我正在開發類似 Food Panda 的應用程式。我正面臨一個問題。我正在計算司機的支出（例如，如果司機每個訂單賺取 4.3 美元）我試圖獲得每個月的總和，但是當司機停止服務時，我的代碼為這些月份分配了相同的價值。

請告訴我我的代碼做錯了什么：

parameters: toDate=2020-10-21&fromDate=2021-11-21

const resturantOrders = await DelivigoOrder.findAll({
  attributes: [
    "Id",
    "OrderNumber",
    "OrderStatusId",
    "TotalPrice",
    "OrderAcceptTime",
    "DriverId",
    "ResturentId"
  ],
  where: {
    DriverId: driverId,
    IsActive: true,
    // OrderAcceptTime: { [Op.between]: [fromDate, toDate] },
    $or: [
      { OrderStatusId: 50 },
      { OrderStatusId: 55 },
      { OrderStatusId: 60 },
      { OrderStatusId: 70 },
      { OrderStatusId: 80 },
    ],
  },
});

var months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct ", "Nov ", "Dec"];

var orderPayouts = [];
let payout = 0;
for (let index = 0; index < months.length; index  ) {
  const element = months[index];

  for (let index = 0; index < resturantOrders.length; index  ) {
    const order = resturantOrders[index];

    if (element === InternalServices.getMonthName(order.OrderAcceptTime)) {
      console.log(element, index, "in");
      payout = payout   4.3;
    }
  }

  orderPayouts.push({
    month: element,
    payout: payout
  });
};

輸出

{
  "result": [{
    "month": "Jan",
    "payout": 55.899999999999984
  }, {
    "month": "Feb",
    "payout": 55.899999999999984
  }, {
    "month": "Mar",
    "payout": 55.899999999999984
  }, {
    "month": "Apr",
    "payout": 55.899999999999984
  }, {
    "month": "May",
    "payout": 55.899999999999984
  }, {
    "month": "Jun",
    "payout": 55.899999999999984
  }, {
    "month": "Jul",
    "payout": 55.899999999999984
  }, {
    "month": "Aug",
    "payout": 55.899999999999984
  }, {
    "month": "Sep",
    "payout": 55.899999999999984
  }, {
    "month": "Oct",
    "payout": 150.5
  }, {
    "month": "Nov",
    "payout": 150.5
  }, {
    "month": "Dec",
    "payout": 150.5
  }]
}

驅動程式僅在 1 月和 10 月的兩個月內作業，但我的代碼將 Jan 值分配給與 OCT 相同的所有其他月份。

uj5u.com熱心網友回復：

您ley payout在回圈之外宣告。您應該考慮在回圈內宣告它

...
for (let index = 0; index < months.length; index  ) {
  let payout = 0;
  const element = months[index];
...
