How to loop through an array in jquery?

Question

JavaScript

Good afternoon, I can not figure out how to split the array correctly.
I am making a request via Ajax. On the server there is a selection in basis.

while ($res = mysql_fetch_array($query)){
  echo json_encode([
     'family'=>$res['family'],
      'name'=>$res['name']	
            ]);
}

I receive data like this.

var obj = JSON.stringify(data)
data = JSON.parse(obj);

The data in data .

{"family":"Петров","value":"Иван"}
{"family":"Иванов","value":"Петр"}
{"family":"Сидоров","value":"Вадим"}

I can't figure out how to loop through them.

Answer 1

$res = array();
while ($res = mysql_fetch_array($query))
    $res[] = array('family'=>$res['family'], 'name'=>$res['name']);
echo json_encode($res);

Then an array will be returned to JS, which can be iterated through each.
