jquery - Why is responseText returning blank? -


i have database table fields contain latitude , longitude coordinates of positions. want create markers google map view using information database.

i've implmented query function 

function getcords(){   $link = connectdb();   $query = "select * tour";   $results = mysqli_query($link, $query);    $jsonarray = array();   while ($row = mysqli_fetch_assoc($results)){     $jsonarray[] = array('filename' => $row['filename'], 'lat' => $row['lat'], 'lon' => $row['lon']);    }  return json_encode($jsonarray); }

when call function php page, returns usual json format.

my issue executing ajax query. have query function above in php scripts file containing 6 or utility functions controlling login, logout, registration , like. query database via jquery, tried 

var request = $.ajax({   type:"get",   url: "includes/phpscripts.php?action=cords",   type: "json" });  var response = request.responsetext;

my problem response empty. due formation of url or other reason?

   $.ajax({       type:"get",       url: "includes/phpscripts.php?action=cords",       datatype: 'json', // necessary, because you're sending json server       success: function(response) {  // response catch within success function         console.log(response);       }     });

or 

   var request = $.ajax({       type:"get",       url: "includes/phpscripts.php?action=cords",       datatype: 'json', // necessary, because you're sending json server     }).done(function(response) {        console.log(response);     });

note

instead of return json_encode($jsonarray);, use echo json_encode($jsonarray);
