Please add proper header in server side, sometimes it's create issue.. PHP

header("Content-type: text/json");
echo json_encode($array);

And in jQuery, please make sure the response in json object... if response may be string not an object then please parse response in json object, There no need $.each loop, please try this please see blow

$.ajax({
            url:"XXXX?callback=?",
            type:'GET',
            dataType:'json',                
            success:function(output){
               var response_obj = {};
               try {
                 response_obj = jQuery.parseJSON(output)[0];
              }catch(e){alert('error==>' + e);}
                    $('#result').append('<p>Row username : UserName'+response_obj.Username+'Password'+response_obj.Password+'</p><br>');

            }
        });         
      });

I hope, issue would be resolved.

$.each(output,function(key,value){
                        $('#result').append('<p>'+key+': '+value+'</p><br>');
                    });

to access specific fields

$('#result').append('<p> UserName:'+output.Username+'Password :'+output.Password+'</p><br>');

here how can i split Username alone?

Miller Over a year ago

you are iterating in $.each() to fecth all the key value pairs in the row

Miller Over a year ago

if you want to access only Username you dont need the $.each()

   $.each(json, function() {
          $.each(this, function(name, value) {
            console.log(Name+ '=' + Value);

          });
        });

Can you just verify whether this code is giving you any results..
