I find! It is my AJAX request! It doesn't like object.That why I do this:

/* fonctionnalité du bouton envoyer de la page ajout et consultation*/
		var $donnees_get = "";
		var $liste_ajax = "";
		$donnees_get = $("#liste_produit").getCol('eta_actif',true);
		for ($valeur in $donnees_get){			
			$liste_ajax = $liste_ajax + '|("' + $donnees_get[$valeur].id.substring(0,5) + '","' + $donnees_get[$valeur].id.substring(6,9) + '","' + $donnees_get[$valeur].value + '")' ;
		}
		$liste_ajax = $liste_ajax.substring(1);

		$.ajax({
			type: "POST",
			url: $url_aj,
			data: "typ_requete=enr_grid&liste_ajax="+ $liste_ajax,
			success: function(contenu){
				/*alert(contenu);*/
			},
			error: function(objet,type){
				alert('error: ' + type);
			}
		});

And after that, Everything work in my Php page. I do this: 

if ($_REQUEST['typ_requete'] == 'enr_grid') {
	$donnees = explode("|",$_REQUEST['liste_ajax']);
	foreach ($donnees as $valeur){
		$id = explode(',',$valeur);
		$SQL = "UPDATE rf.ft_produit_codif SET eta_actif = ".substr($id[2],0,3)." WHERE cod_produit = ".substr($id[0],1,7)." AND cod_origine = ".substr($id[1],0,5);
		$result = mysqli_query($link,$SQL);
	}
}

Nothing work it's very despairing.

maybe like this but I am not sure it will work with your type of string:

var contenu2=JSON.parse(contenu);

alert(contenu2[1].value);

var contenu2 = JSON.parse(contenu);
alert(contenu2[1]);

I have a pb to extrat information from array wich is returns by the method: getCol.

This is my cod in my javascript page.

var $tb = $("#liste_produit").getCol('eta_actif',true);
		$.ajax({
			type: "POST",
			url: $url_aj,
			data: "typ_requete=enr_grid&tb="+ $tb,
			success: function(contenu){
				alert(contenu);
			},
			error: function(objet,type){
				alert('error: ' + type); 
			}
		});

the result is like this: [{id:1,value:val1},{id:2,value:val2},{id:3,value:val3},{id:...,value:..}]

How  can I get back various values of the various array.

Thank you for your help.
