I have json data obtained form my server and i want to put in a list, i already read Convert JSON To Array Javascript and Converting data from JSON to JavaScript array but i can't figure out what of all the options can i use in my code my json is like this:

{"response": {"user": [{"username": "", "description": "", "picture_url": "", "name": "", "phone": ""}]}, "success": true}

and i want to put it on an array like this:

[{username: "",description: "", picture_url: "", name: "", phone: ""}]

what can i do for this? i already try the answers of this: Converting JSON Object into Javascript array

i also try some functions like this:

$.each(data, function(i,obj){
                $(arr).append(obj.username+'</br>');
                $(arr).append(obj.description+'</br>');
                $(arr).append(obj.name+'</br>');
            });

and this:

var results = data;
            var arr = [], item;
            for (var i = 0, len = results.length; i < len; i++) {
                item = results[i];
                arr.push({username: item.username, description: item.description, name: item.name});
            }

but with the second one dont show anything and dont show any error, with the first one, showme an unespecthed error arr is not defined.

post your server side script – VMcreator Aug 4 '15 at 1:15
    
Do you need anything more than this? var user = JSON.parse(responseJson).response.user; var putItInAnArrayLikeThis = [user]; – widged Aug 4 '15 at 14:28

In your sever side script the array that will be converted to json should look like this:

$array=array("response"=>array(
                                   "user"=>array(array("username"=>"",
                                                       "description"=>"",
                                                       "picture_url"=>"",
                                                       "name"=>"",
                                                       "phone"=>"")),
                                   "success"=>true
                              )
             );
echo json_encode($array);

I think in your server side the "user" array format looks like

"user"=>array("username"=>"",
              "description"=>"",
              "picture_url"=>"",
              "name"=>"",
              "phone"=>"")

Instead of that, "user" array should be nested, like my first example.

"user"=>array(array("username"=>"",
                    "description"=>"",
                    "picture_url"=>"",
                    "name"=>"",
                    "phone"=>""))

After converting to json using javascript the output will exactly be:

user:[{username: "",description: "", picture_url: "", name: "", phone: ""}]

Assuming your JSON is like this as posted:

{"response": {"user": [{"username": "", "description": "", "picture_url": "", "name": "", "phone": ""}]}, "success": true}

You already have the exact data structure you want at .response.user.

So code would be simple:

var json = '{"response": {"user": [{"username": "", "description": "", "picture_url": "", "name": "", "phone": ""}]}, "success": true}';
var obj = JSON.parse(json);
var theArrayYouWant = obj.response.user;

This doesn't require any transformation at all (other than deserializing the JSON string), you are just extracting a portion of the data structure represented in JSON.
