使用JavaScript过滤器，如何通过从同一数组中动态获取月份来编写此代码？

Question

        let janFilteredData = YearlyExpense.filter((data) => {
        return data.month === "January"
    })
    let febFilteredData = YearlyExpense.filter((data) => {
        return data.month === "February"
    })
    let marFilteredData = YearlyExpense.filter((data) => {
        return data.month === "March"
    })
    .
    .
    .
    . 
    .

    let decFilteredData = YearlyExpense.filter((data) => {
        return data.month === "December"
    })

由于我要显示当前每个月的条形图，所以我需要将该值作为每个月的支出总数传递给c3图表。

YearlyExpense数组是;

const MonthlyExpense = [{
UserID: "1",
UserName: "George",
MonthlyExpenseDetails:[
    {
        TotalAmount: "70000",
        TotalNoOfBills: 16,
        ExpenseTypeDetails: [
            {
                BillType: "Taxi",
                NoOfBills: 4,
                Amount: "30000",
                Approved: {
                    TotalAmount: 10000,
                    TotalNoOfBills: 1
                },
                Rejected: {
                    TotalAmount: 10000,
                    TotalNoOfBills: 0
                },
                Pending: {
                    TotalAmount: 10000,
                    TotalNoOfBills: 3
                }
            },
            {

                NoOfBills: 4,
                Amount: "10000",
                Approved: {
                    TotalAmount: 10000,
                    TotalNoOfBills: 1
                },

    },
]}]

export const YearlyExpense = [
{ month: "January", expense: MonthlyExpense },
{ month: "February", expense: MonthlyExpense },
{ month: "March", expense: MonthlyExpense },
{ month: "April", expense: MonthlyExpense },
{ month: "May", expense: MonthlyExpense },
{ month: "June", expense: MonthlyExpense },
{ month: "July", expense: MonthlyExpense },
{ month: "August", expense: MonthlyExpense },
{ month: "September", expense: MonthlyExpense },
{ month: "October", expense: MonthlyExpense },
{ month: "November", expense: MonthlyExpense },
{ month: "December", expense: MonthlyExpense }]

我正在为react c3js图形生成此数据。在这种情况下，如何在不重复如上所述的代码的情况下，根据各个月份获取数据。

Answer 1

您可以尝试这样的事情：

function monthlyFilteredData(yearlyExpense,month){
  return yearlyExpense.filter(data => data.month === month)
}

let janFilteredData = monthlyFilteredData(yearlyExpense, 'January')
