你能指导我一个问题吗，我每次按下按钮时都会尝试更改颜色

Question

My problem is that I call my function within my for, but only a part changes color and not above each record, the buttons work but the color of the corresponding row does not change, it had occurred to me to send a value that could be the pk of my table and this one that is changing in the for, if you know any way to achieve that I would really appreciate it我的问题是我在我的 for 中调用了我的 function，但只有一部分改变了颜色，而不是每条记录上方，按钮工作但相应行的颜色没有改变，我想到发送一个可能是的值我的桌子的 pk 和这个正在改变的桌子，如果你知道任何方法来实现它，我会非常感激

It is difficult to understand your question.很难理解你的问题。 But I believe you are looking for the below answer.但我相信您正在寻找以下答案。 Let me know if it helps you.让我知道它是否对您有帮助。

I think you have placed the ID in the wrong tags, though.不过，我认为您将 ID 放置在错误的标签中。 Changed the id to where you want to change the colour.将 id 更改为要更改颜色的位置。 I haven't tested the code also.我也没有测试过代码。

<?php 
if ($alumnos && $sentencia) {
    foreach ($alumnos as $key => $row) {?>
        <tr>
            <td id="prueba2_<?php echo $key; ?>"></td>   
            <td id="prueba0_<?php echo $key; ?>"></td>
            <td id="prueba1_<?php echo $key; ?>"></td>
            <td>
                <button  type="button" onclick="cambiarColor(<?php echo $key; ?>, 2, 'green');">Inicio</button>
                <button type="button" onclick="cambiarColor(<?php echo $key; ?>, 0, 'blue');">Proceso</button>
                <button type="button" onclick="cambiarColor(<?php echo $key; ?>, 1, 'red');">Fin</button>
            </td>
        </tr>
        <tr>
            <td><?php echo $row['idZonas']; ?></td>
            <td><?php echo $row['nombreZona']; ?></td>
            <td>&nbsp;</td>
        </tr>
<?php 
    }
}
?>
<script>
    function cambiarColor(id, eleid color){
        document.getElementById('prueba'+eleid+'_'+id).style.backgroundColor = color;
    }
</script>
