您的表结构无效。此外，计时器\u 1无法找到所需的文本，这是它无法工作的原因 您的php代码应该如下所示：
<table class="table">
<?php
$table = mysqli_query($connection, 'SELECT * FROM Timers');
while($row = mysqli_fetch_array($table)){
?>
<tr id="<?php echo $row['ID']; ?>">
<th>Timer 1</th>
<td data-target="Timer_1">
<?php echo $row['Timer_1']; ?>
</td>
<th>
<a href="#" data-role="update" class="btn btn-primary" data-id="<?php echo $row['ID']; ?>">Update</a>
</th>
</tr>
<?php
}
?>
</table>
修复你的HTML布局，这可能会使事情正常工作。格式不正确的HTML通常会使更复杂的布局不可用work@RiggsFolly非常感谢。对不起。但标签下存在主要问题。我仍然不确定为什么该值没有显示。您好，非常感谢。我能够在示例中的文本字段中显示mySQL值。但当我尝试更新mySQL表时，它并没有得到更新。我做错了什么？我已在“编辑”下更新了有问题的代码。此$\u POST['ID']应为$\u POST['ID']，因为您已在ajax调用中将ID作为参数传递，而不是ID。谢谢，这是缺少的：
<table class="table">
<?php
$table = mysqli_query($connection, 'SELECT * FROM Timers');
while($row = mysqli_fetch_array($table)){
?>
<tr id="<?php echo $row['ID']; ?>">
<th>Timer 1</th>
<td data-target="Timer_1">
<?php echo $row['Timer_1']; ?>
</td>
<th>
<a href="#" data-role="update" class="btn btn-primary" data-id="<?php echo $row['ID']; ?>">Update</a>
</th>
</tr>
<?php
}
?>
