I haven’t got that far yet I don’t know how to do that at the moment.
I need a json parser do. I i really need is to return a empty string
that is either ‘true’ or ‘false’

yes the piece of code you have posted expects json to be recieved from getemailaddress.php

in your php file try putting

<?php

   echo json_encode("hello");

?>

and most probably things will work out for you

EDIT

for example from the php script you are sending an array like

$responseVar = array(
                    'message'=>'some message',
                    'value'=>'some value'
                    );

in the success handler of your ajax request you can do something like

success:function(data){
 console.log(data.message);
 console.log(data.value);
}
