[已修改] 這里有一點幫助就可以了。我遇到了 for 回圈的問題。我有一個 for 回圈嵌套在另一個回圈中。外回圈只有元素級別，而嵌套僅包含 27 個專案。問題是設定在退出之前只能運行嵌套陣列的 22 個專案。
設定在服務器端運行，在 node.js 中完成。客戶端是 React，它通過 websocket 與服務器通信。從控制臺報告來看，node.js 運行了上述代碼 3 次；在所有這些時間里，只有 22 個專案從預期的 27 個專案中回圈出來。

下面的代碼。我很感激任何幫助。謝謝你。

uj5u.com熱心網友回復：
我用你的資料嘗試了你的代碼，正如預期的那樣，它遍歷了所有 27 個專案。但是由于不滿足某些條件，您將設定innError = true為第 22 條記錄并且永遠不會將其設定回false.
因此，之后的所有專案都將被視為它們也有錯誤（這可能會讓您相信它們沒有被迭代）。只需嘗試console.log(j)在內部回圈中添加as first 陳述句即可。你會看到，它會列印出從0到26...的所有值
