javascript - 如何在 For...of 循环中替换数组中的所有 NaN 值

Question

如果我有以下数组

let initialdates = [2019-12-07,2019-12-08, NaN-NaN-NaN]

为什么以下内容不适用于我删除 NaN 的过程....

let initialdates = [2019 - 12 - 07, 2019 - 12 - 08, NaN - NaN - NaN]
for (let [index, dateField] of initialdates.entries()) {
  if (isNaN(dateField)) {
    initialdates[dateField] = "found issue";
  }
}
console.log('the final array is: ' + initialdates);

它仍然打印出来......

最终数组为:2019-12-07,2019-12-02,NaN-NaN-NaN

Answer 1

initialdates[dateField] = "found issue";

应该是

initialdates[index] = "found issue";
