這是我的代碼。這是德國Enigma機器的草稿。我試圖讓我實際上通過機器運行的消息,除非它在第二次運行該函數之前不會創建該消息。奇怪的是我知道函數運行,因爲我看到它的一部分執行,但就代碼而言toWorkWith
在第一次運行時是空的,並在第二次運行時填充?我的功能運行,但只做第二次嘗試的一部分

在'var code = []'之後和'document.simulator.rotor3.value = alphabet [newPos]'和'workingMessage =「」' –
@AlexW之後缺少';'但很抱歉導致目前的問題。任何其他想法? – ChapmIndustries
@ChapmIndustries如果你的代碼很好而且健壯,那麼發現錯誤會更容易。有時候一個簡單的分號,逗號等可以成爲Javascript引擎中的扳手。我會建議匹配你的括號,看看你在Javascript控制檯上得到的輸出。 –
