         while($hasta = mysqli_fetch_array($query)){

         echo $hasta['name'];}

For your ajax code, you need to add dataType parameter and add the parameter of success: function(data) , so like this:

$.ajax({
            url:'dokyon.php'//current page
            type: 'POST',
            data:{tc:tc},
            dataType:"html",
            success: function(data){
                alert(data);

            }
        });

For additional: always do debuging for sending data with inspect element of browser. Hopefully it will be success for you :)
