很难理解你的问题。 但我相信您正在寻找以下答案。 让我知道它是否对您有帮助。
不过,我认为您将 ID 放置在错误的标签中。 将 id 更改为要更改颜色的位置。 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> </td>
</tr>
<?php
}
}
?>
<script>
function cambiarColor(id, eleid color){
document.getElementById('prueba'+eleid+'_'+id).style.backgroundColor = color;
}
</script>
