[Answered ]-Json recognised as String

As harish-reddy said, the dataType property sets the behaviour to what you expect the response to be. That said the “data” argument of the success function is already a JavaScript object.

Refer to http://api.jquery.com/jQuery.ajax/

As arpit-solanki mentioned the message property inside the response object is not an array, but is interpreted as a string (notice the starting ‘”‘), therefor you either change the server side to send you an actual array or you must JSON.parse(data.message) to obtain its content.

The response you are receiving is already executed by JSON.stringify.Either you must use JSON.parse or change the logic at the server end
