Answer 1

When you made ajaxCall return data in json format like

json_encode(array("phone"=>'123-12313',"email"=>'test@test.com','city'=>'Medicine Hat','address'=>'556 19th Street NE'));

above shown

then parse it in jQuery and put the value in different selectors like

 var Vals    =   JSON.parse(response);
 // These are the inputs that will populate
 $("input[name='phone']").val(Vals.phone);

above shown.
