How to foreach much objects in array - jquery?

Question

In PHP file, I have the following concept:

// return assoc
$res = DBQUERY;
foreach ($res as $key => $value) {
$retval[$cnt] = array("id_enumeration" => $key, "display_value" => $value);
$cnt++;
}
echo json_encode($retval);

In success result I got in Firebug array of objects like this:

[ {"id_enumeration": 3602, "display_value": "Test1"}, {"id_enumeration": 3604, "display_value": "Test2"}, {"id_enumeration": 3605, "display_value": "Test3"}, {"id_enumeration": 3607, "display_value": "Test4"}, {"id_enumeration": 3610, "display_value": "Test5"} ]

I'm trying to perform this code by foreaching:

success: function(data) {
   // get array:
   $.each(data, function(idx, obj) { 
      // get each object:
      $.each(obj, function(key, value) {    
         console.log("Display value: " + value.display_value + " ID enumeration: " + value.id_enumeration);                             
      });
   });
}

But variables in console.log are undefined. How to each much objects in array? What is the best way to do that?

You have obj which is an array of objects which has the display_value property, so you can access it via obj.display_value in the first $.each() loop, there is no need for the second one

   $.each(data, function(idx, obj) { 
      console.log("Display value: " + obj.display_value + " ID enumeration: " + obj.id_enumeration);                             
   });

Demo: Fiddle

$.each(data, function(idx, obj) { 							  console.log("Display value: " + obj.display_value + " ID enumeration: " + obj.id_enumeration);                              });

Still undefined.

Works now... My mistake, forgotten dataType: "json".
