我遇到了這個聊天系統的一些問題。它不斷給我回這些錯誤，它不應該。Javascript彈出錯誤
它不斷給我彈出說：「地鼠」和
我看過了代碼，但不能發現任何錯誤這很煩人。任何人都知道什麼錯

由於提前，
這是很好，你張貼你的代碼，但請嘗試縮小它一點點，你認爲造成的問題。例如。 *什麼時候發生？點擊某些後？找到與之相對應的代碼。此外，如果它說'gopher'，請嘗試在代碼中搜索該單詞。 – Armatus 2012-04-08 09:25:23
它不會一直髮生，它主要發生在大約5分鐘左右之後。我嘗試了使用Google搜索並查看問題所在，甚至試圖將文件移動到相同的文件夾中，但未修復它。感謝無論如何:) – 2012-04-08 09:27:28
