Question

i have this php code:

$query = mysql_query("SELECT * FROM table WHERE id=$id");
while($item = mysql_fetch_assoc($query)){
    $dataArray['var1'] = $item['var1'];
    $dataArray['var2'] = $item['var2'];
    $dataArray['var3'] = $item['var3'];
    array_push($return_arr,$dataArray);
}

echo json_encode($return_arr);

it’s in my ajax.php file

Then I’m using jquery to send there id via ajax request:

$.ajax({
    type: "POST",
    url: 'ajax.php',
    data: 'id='+id,
    success: function(data) { 
        alert(data);
    }
 });

and it alerts me this: [{"var1":"somevarhere","var2":"somevarhere2","var3":"somevarhere3"}]

can someone tell me please how I can access for ex. var3 to get somevarhere3?

thanks

Ok, I found the solution. Thanks to Pascal MARTIN I got the idea to parse the result so I used this:

data = data.substring(1,data.length-1);
data = $.parseJSON(data);
alert(data.var3);

first line removes [],
second line parses JSON to Object,
and third line accesses the property
