雖然最近ZORK重新創建了一款遊戲，但我遇到了一個問題，不知道是什麼原因造成的，或者如何處理它。Javascript的限制或簡單的錯誤？
我在提示框上使用了一個while循環，比較用戶輸入和switch（）情況，並返回一個響應。我一直在構建它一段時間，並有超過600行的JavaScript。
在爲遊戲的另一個元素添加了幾行後，我注意到腳本在使用過程中突然退出（這意味着提示不再顯示）。版本，我三重檢查錯誤，但找不到任何。我查閱了某些瀏覽器的JavaScript限制，並表示5,000,000是允許的最大語句。我認爲只有600條線路，甚至是循環線路，在使用一兩分鐘後就可以達到這個數量。
所以我很難過。我不知道是什麼導致了這個問題，或者如何解決或解決這個問題。我通過js minifier運行它，並得到與以前相同的結果。

我懷疑你應該做四重檢查。 – Pointy 2015-03-31 15:23:05
然後在這裏貼出實際的代碼，儘管有「多少行」。問題會很快結束，否則。 – 2015-03-31 15:23:44
也許控制檯出現錯誤。 – epascarello 2015-03-31 15:24:14
