Get elements of json_encoded array in javascript

Question

i passed a json_encoded array to javascript. Now i would like to acces that array to get the different elemtnts.

i print it out in the console.log() and i get this array:

array(1) {
  [16]=>
  array(2) {
    [3488]=>
    array(1) {
      [0]=>
      array(2) {
        ["article_no_internal"]=>
        string(6) "999184"
        ["article_name_internal"]=>
        string(29) "Geschenkbox Kerzenschein 2011"
      }
    }
    [2615]=>
    array(1) {
      [0]=>
      array(2) {
        ["article_no_internal"]=>
        string(6) "700469"
        ["article_name_internal"]=>
        string(29) "Hotelscheck RomantischeTagef2"
      }
    }
  }
}

This is about right. How can i access the article_name of the second array, with the ID 2615?

found a related question here reading a jsone object, hope for some better explebation or answer. Thanks.

EDIT:

As it seems i made a mistake, i showed a php var_dump in the console. When i try to show the javascript array in the console i get undefined.

You get that output from console.log?! That looks like var_dump in PHP. How exactly are you passing that array? — deceze

@deceze you are right it was a lost var_dump in php. Now it seems i dont have anything in my console this is how i encode: $shipping_part_list_array = json_encode($db_obj->getArticleList($elements),true); and how i pass to javascript: var array = <?php echo $shipping_part_list_array; ?>; in the console now i have undefined. — Barta Tamás

if i go like this var array = <?php echo json_encode($shipping_part_list_array); ?>; it says there are no childe objects. — Barta Tamás

Since JSON means "JavaScript Object Notation" you don't need to do anything to access the object's items.

For example you can access:

jsonObject[2615][0]["article_name_internal"]

if this object is String, use eval to convert the string to a JavaScript object and access the items in the same way with the previous example.

var jsonObject = eval(jsonstring);
jsonObject[2615][0]["article_name_internal"]

json_encode($db_obj->getArticleList($elements),true); this is how i encode in php var array = <?php echo $shipping_part_list_array; ?>; and like this i pass the array, but when i console.log(array); i just get undefined prototype.
