這裏很新的Javascript，我想我有一個邏輯問題。所以基本上，我正在建造一個hang子手遊戲，而且我遇到了雙字母的問題。例如，如果這個詞是食物，當我輸入一個「O」時，它將通過for循環，首先擊中O，將它推到屏幕上，並在其軌道上停下來。我可以做任何我想要的第一個「O」，但第二個或任何其他重複的信件會被忽略。現在，我直接在for（）循環的開始處編寫的警報將成功打印「O's」，並將其記錄到控制檯，甚至可以寫出document.write（splitWord [m]）;JavaScript for循環不重複字符串
對我來說，我認爲它必須是我的if語句。我可能100％錯了，但我認爲if語句告訴它看到第一個「O」，做括號內的內容，然後繼續下一個字母，跳過任何雙打。如果我對此有所瞭解，繼續循環將會是更好的選擇，所以「O's」都會被填滿。如果我完全錯了，完成這項任務會是更好的行動。任何幫助將非常感激。
感謝

你是什麼reg表達式'playerGuess'。 –
它是一個全局變量，用於保存用戶通過按下鍵輸入的字母。我沒有發佈整個腳本，因爲它超過200行。如果我這樣做會有幫助嗎？ – rmes
