php - Jquery Ajax using json is getting a undefined value -

$.ajax({                     type: "post",     url: "check.php",     data: "checkit=" + $("#checkemail").val(),     success: function(response){         $("#usercheck").html(response.status);         if(response.status == true){             alert("yay");         }else{             alert("dsfds");         }     } }, 'json'); 

someone here suggested doing ajax returns using json...

here php file returning json..

$data = {success:true};     echo json_encode($data); 

im getting undefined return. perhaps here point me mistake?

you missing

datatype: 'json' 

and php wrong:

$data=array('status'=>true); 

update

here few suggestions try:

1) 'datatype' (case-sensitive believe)

2) try using 'contenttype' option so:

contenttype: "application/json; charset=utf-8" 

i'm not sure how it's used in request post url, not in response. see article more info: http://encosia.com/2008/06/05/3-mistakes-to-avoid-when-using-jquery-with-aspnet-ajax (it's written asp.net, may applicable)

3) triple check output of post url , run output through json validator absolutely sure it's valid , can parsed json object. http://www.jsonlint.com

hope of helps!
