這有點讓代碼混淆（我認爲），但我希望你能理解它，（是的，我知道我的Mysql API是不是最好的，但我會改變當我有時間（這是一個大腳本））PHP/JQuery - PHP腳本每5秒運行一次，但jquery函數只運行一次
嗯，我有一個PHP腳本，每5秒運行一次，在JQuery中做一個通知，如果存在任何行帶有用戶user_id的friend_requests表，並且如果存在，則運行jquery通知（類似於facebook），表示用戶已經向他發送了朋友請求。
但問題是，PHP腳本每5秒運行一次，但腳本中的說明在屏幕中打開通知框的Jquery函數只運行一次..如果我有一行user_id用戶，如果是第一次運行php代碼，就運行通知（如果前5秒已經過去，如果該行在5秒之後纔出現，則通知框不會出現），只要該行進入前5秒。 （但是，PHP代碼的其餘部分完美地運行）

我試過了，現在腳本甚至不運行o_o –
Omg !!!你有任何要求和迴應嗎？ –
@DavideGonçalves這是我的錯誤。它應該是'.getMilliseconds（）'而不是'getMilliseconds'。謝謝。 '（）'犯了錯誤。 –
