pass an id and a php name to javascript and return it

in php I take an id and a name from my database in mysql and show each name in a checkbox. The problem is that I need to mark several and give a button to delete them and for that I show in javascript a message confirm for security. To the message confirm I pass the names but I also need to pass the id since when I go back to php I need the id to carry out another query and delete the ones I have marked.
In the php:

echo "<form name=form method=POST action=principal.php?orden=desasignar>";
                    //Recorro la matriz para sacar el valor de todos que es el nombre
                    for($i=1;$i<=count($resultsetAsignado);$i++){
                        echo "<td><input type=checkbox name='clientes' value='".$resultsetAsignado[$i][1]."' id='idDelCliente'>".$resultsetAsignado[$i][1]."</td>";
                        //mandamos los id_de los clientes
                        echo "<input type=hidden name='id' value=".$resultsetAsignado[$i][0]." >";
                        echo "</tr>";
                    }
                echo "</table>";
                //boton
                echo "<input type=button name=boton value='Desasignar' onClick='confirmacion();'>";
                echo "</form>";

In javascript

    function confirmacion(){
       //Realizo el confirm y cojo los nombres y los muestro en el confirm
      //y despues lo mando con submit
      document.form.submit();   
    }

In the 0 I keep the id and in the 1 the name.

Any ideas? If you do not understand something tell me
