I'm having trouble parsing JSON in Javascript.
The response i'm getting from PHP when making a request is:
[
{'name': 'John', 'lastName': 'Doe','age':'25', 'height': '170',
'weight': '120'},
{'name': 'Jane', 'lastName': 'Doe','age':'26', 'height': '175',
'weight': '121'},
{'name': 'Jack', 'lastName': 'Doe','age':'27', 'height': '180',
'weight': '122'} ]
How would I go about parsing this in Javascript? Am I not encoding it
correctly on the PHP Side?
Here's my JAVASCRIPT:
    $.get("includes/functions_inside.php", {"function" : "getAppList"},
        function(data, textStatus){
            alert( data[0] );
        }
    );
Here's my PHP:
    $AppListQuery = $insideDB->customQuery($query);
    $rows = array();
    while($r = mysql_fetch_assoc($AppListQuery)) {
     $rows[] = $r;
    }
    print json_encode($rows);
Thanks in advance!
