Hola
Jarancho
Prueba este ejemplo:
Código PHP:
<html>
<head>
<script type="text/javascript">
var fila = null;
function pulsar(obj) {
obj.style.background = 'green';
if (fila != null && fila != obj)
fila.style.background = 'white';
fila = obj;
}
</script>
</head>
<body>
<table>
<tr onclick="pulsar(this)"><td>..</td><td>..</td><td>..</td></tr>
<tr onclick="pulsar(this)"><td>..</td><td>..</td><td>..</td></tr>
<tr onclick="pulsar(this)"><td>..</td><td>..</td><td>..</td></tr>
<tr onclick="pulsar(this)"><td>..</td><td>..</td><td>..</td></tr>
</table>
</body>
</html>
Saludos,
