I keep getting an error parsing what seems to be valid JSON. The parse call is done ina handler to an Ajax call to a php script that is returning:

echo json_encode(array("success"=> false, "error_message"=> "error"));

The code bit handling the response:

function(returnedData){
                console.log(returnedData);
                var response = JSON.parse(returnedData);

The console.log call is printing

{"success":false,"error_message":"error"}

If I take this, put it between quotes and manually call JSON.parse in the console, then it works fine.

Any ideas what might be going wrong? Thanks in advance!

    Your json isn't json. It's html + json, most likely a php warning/error, causing the json to be considered corrupted, Look at the RAW response from the server to see what this html is. – Marc B Aug 15 '16 at 19:08
  • My guess is that your PHP file is returning HMTL, not your JSON. Check the network tab in your console – Rob M. Aug 15 '16 at 19:08
  • I can't see any way that `console.log(returnedData);` could give output that doesn't include a `<` character when `var response = JSON.parse(returnedData);` throws an error complaining about a `<` character. – Quentin Aug 15 '16 at 19:09
  • It looks as if the data sent by the server has plain text format. Follow [this procedure](http://stackoverflow.com/a/6599300/1505348) to use JSON format instead. And please reply here if it does work :) – Lucio Aug 15 '16 at 19:10
