如何在不使用 for 循環的情況下迭代 FormData entries() 數組

Question

我嘗試遍歷 FormData 條目（）對象。 ESlint 給了我一個錯誤，我真的不應該像下面那樣做： iterators/generators require regenerator-runtime, which is too heavyweight for this guide to allow them. Separately, loops should be avoided in favor of array iterations. iterators/generators require regenerator-runtime, which is too heavyweight for this guide to allow them. Separately, loops should be avoided in favor of array iterations.

for (const row of data.entries()) {
  const search = row[0].replace('internal_', '');

  if (search.length > 0 && search.substr(1, 3) !== 'ext') {
    currentCTX.data[search][2] = row[1];
  }
  const currentData = JSON.stringify(currentCTX.data);
  const { feedId } = window;
  const params = { userSave: currentData, id: parseInt(feedId, 10), channel: 'import' };
  const res = fetchData(`${apiUrl}mapping`, params).then(() => window.location = '/');
}

但是entries()沒有 forEach() 所以我不能使用它。

執行上述操作的干凈方法是什么？

不使用for..of ，而是將.entries()迭代器擴展到一個數組中，以便您可以在其上使用forEach ：

[...data.entries()].forEach((row) => {
  // ...
