Question

我想使用tableedit JQuery插件。这是一个代码示例。表的编辑工作正常。但删除不起作用。我收到错误： Tabledit Ajax fail =＆gt; parsererror：SyntaxError：意外的令牌＆lt;在JSON中

我不明白为什么。我在这里读了一些帖子，但我还有问题。

这是我的代码：

<?php
$connect = mysqli_connect("localhost", "root", "root", "testing");
$query = "SELECT * FROM tbl_user ORDER BY id DESC";
$result = mysqli_query($connect, $query);
?>
