如何使用 javascript for 循環創建新數組。 我收到錯誤“圓形對象對象”

Question

我需要通過用ajax划分返回的數組來創建一個新數組。 我將復制具有與此數組數量一樣多的 offerCurrencyTypeExchanges 值的對象，並將代碼和費率值寫入“標簽”值。 但我想我在循環中創建了一個錯誤。 將最后一個值復制到所有。

結果在 jsfiddle https://jsfiddle.net/xd68no54/ 中看起來更好

var res = [{
    id: 3,
    name: "Türk Lirası",
    code: "TRY",
    offerCurrencyTypeExchanges: [],
    label: "Türk Lirası (TRY)"
  },
  {
    id: 4,
    name: "USD",
    code: "USD",
    offerCurrencyTypeExchanges: [{
        exchangeRateId: 33642,
        localize: "Alış",
        value: 9.2857,
        valueSection: 1
      },
      {
        exchangeRateId: 33642,
        localize: "Satış",

Süleyman TAŞÇI，您能否舉例說明您希望看到的結果？ 我認為這可能會澄清你在問什么。 我很樂意嘗試並提供幫助！

Answer 2

我不是很明白你想做什么，但你可以提取你的對象並用它們做你想做的事情。

const currencyExchangeTypes = res.map((c) => c.offerCurrencyTypeExchanges).reduce((a, b) => a.concat(b), []);
