使用PHP Ajax在MySQL数据库中存储开/关按钮的值

我找到了一个单一ID的教程

我已经根据我的知识修改了多个id，我无法使用ajax获取id。我不擅长ajax。我已经附上了两个代码。谁能告诉我如何修复多个id

我还附上了一个屏幕截图

index.php

    <?php
$query=mysql_connect("localhost","pma","pmapass");
mysql_select_db("testdb",$query);
include("connection1.php");
$result = mysql_query("SELECT * FROM mytable ORDER BY id");
?>

为了你自己；：

请整理你的代码 如果无法从数据库加载某些内容，请在 为什么是2。查询时，您已使用select*？ 然而，这里有一个基于未测试代码的示例：

如果从ajax请求中得到答案，您可以查看浏览器控制台。

很难理解您的代码。。。用php生成js变量名可能不是最好的解决方案。。。你到底想干什么？你的按钮在哪里？我想用那个按钮隐藏数据。我有超过10个带有数据的ID。我希望每个ID上的按钮都能正常工作。这是一个不错的按钮，但按钮滑动不起作用。朋友，我已经解决了这个问题，谢谢你的快速帮助。你能告诉我一个更好的学习ajax的方法吗？对于纯ajax，你可以在这里看看，或者在使用jQuery这样的包装器时看看，或者
