I am having trouble with my jQuery script below, this is a basic stripped down version and even it will not work, I have the php file that the jQuery script makes a call to, I have it set to encode and show a JSON response Then in the jQuery script it should read the value and respond to it but It is not getting the response. Is json.response the wrong way to call a variable in the JSON string that is name response? <?php header('Cache-Control: no-cache, must-revalidate'); header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); header('Content-type: application/json'); // set to retunr response=error $arr = array ('resonse'=>'error','comment'=>'test comment here'); echo json_encode($arr); ?> //the script above returns this: {"response":"error","comment":"test comment here"} <script type="text/javascript"> $.ajax({ type: "POST", url: "process.php", data: dataString, dataType: "json", success: function (data) { if (json.response == 'captcha') { alert('captcha'); } else if (json.response == 'error') { alert('sorry there was an error'); } else if (json.response == 'success') { alert('sucess'); }; } }) </script> UPDATE: I have changed json.response into data.response But this did not make it ork either
