How to access in javascript a json array created from php

Question

i have an array in php like this:

$arr['test'] = "asd";
$arr['test1'] = "asd1";
echo json_encode($arr);

and i get this using jquery post:

$.post("fillScheda.php",{scheda:num_scheda,id:idCliente},function(msg){

});

so in msg there is my json array... i tried to access in some way..

alert(msg[0].test);

alert(msg.test);

but result is always undefined... how can i access to values? can someone help me? thanks!!!

msg.test should work. Can you double check your server is outputting {"test":"asd","test1":"asd1"}, and nothing more via the network tab in your developer tools? — Matt

Try to parse the json object

msg = JSON.parse(msg);

have you tried to set the type of return value of json:

$.post("fillScheda.php",{scheda:num_scheda,id:idCliente},function(msg){

},'json');

You should serve json from the php file with this header:

header('Content-type: application/json');

So the code should be:

$arr['test'] = "asd";
$arr['test1'] = "asd1";

header('Content-type: application/json');
echo json_encode($arr);
exit();
