如果它的字符串沒有改變，那麼頁面必須被緩存按ctrl + f5清除緩存 –

你不保存文件正確。當您嘗試僅打印world..try時更改文件的名稱並運行它。

另一件事是你的瀏覽器緩存文件清除緩存。

你在代碼中沒有問題。

當我用其他名字保存文件並運行它時，它運行完美，但這裏是我的問題，爲什麼發生這種情況？當我想改變任何東西，所以我應該用其他名字保存文件？：| – SFAH

因爲您的瀏覽器正在緩存文件的舊名稱，並從緩存中加載它...清除瀏覽器的緩存...嘗試從其他瀏覽器運行它，你會發現它會完美的工作。 – neophyte

在head標籤中使用'..你的瀏覽器將停止緩存嘗試。 – neophyte
