[jQuery] modify from server two jquery elements in the same time


I would like to modify two jquery elements in the same time from PHP
module. The PHP module is called by .ajax
$.ajax(
{
type: "POST",
url:'my_module.php',
dataType: 'html',
success: function(resultat) { ***** ????? *****},
error: function(requete,iderror) {alert(iderror);}
})
}
<div id=field1>...
<div id=field2>...
PHP code:
echo " ***new value for field1 **** new value for field2 *** "
How to formulate the success function AND the echo instruction ?
