Question

我有一个具有聊天功能的游戏服务器，并将所有玩家的聊天消息记录到我的数据库中。我正在尝试创建一个自动更新数据而不是表本身的表，这是因为在我的桌子上我想要一个每个玩家的下拉列表（来自服务器，禁止播放器，静音播放器，低音播放器等的踢球员）。）但我的JavaScript代码目前每5秒刷新整个表。因此，如果我打开我的下拉列表，当表刷新时，它将关闭下拉列表，此时我已将下拉列表更改为按钮，因为此问题。

这是我的代码：

显示表格的索引页面：

require 'header.php'; ?>

        $('#results').load('includes/online.php');
    }, 3000); // refresh rate in milliseconds.

您可以在每次对数据库进行更改时更新的服务器上存储时间戳。然后，在setInterval中首先从服务器获取上次更新时间，并将其与加载页面时的更新时间进行比较;如果它们不同则刷新页面，否则什么也不做。
