PHP表自動更新數據但不是表

Question

我有一個遊戲服務器，它具有聊天功能並將所有玩家的聊天消息記錄到我的數據庫。我試圖創建一個自動更新數據但不是表本身的表格，這是因爲在我的桌子上我想要一個每個玩家的動作下拉列表（從服務器，禁止玩家，靜音玩家，巴掌玩家等等的踢球員） 。）但我的JavaScript代碼在這一刻刷新整個表每5秒。所以，如果我打開我的下拉列表，當表格刷新時它將關閉下拉列表，此時我已經將下拉列表更改爲一個按鈕，因爲這個問題。

這裏是我的代碼：

索引頁顯示的表：

$(document).ready(function() { 
 
    $.ajaxSetup({ cache: false }); // This part addresses an IE bug. without it, IE will only load the first number and will never refresh 
 
    setInterval(function() { 
 
     $('#results').load('includes/online.php'); 
 
    }, 3000); // refresh rate in milliseconds. 
 
}); 
 
// ]]></script>

您可以在每次更改數據庫時更新的服務器上存儲時間戳。然後，在您的setInterval中，首先從服務器獲取上次更新時間，並將其與加載頁面時的時間進行比較;如果他們刷新頁面不同，否則什麼都不做。
