    <script>

        $(function() {

            $('.submit').click(function() {

                // Get data as array, ['Jon', 'Mike']
                var users = $('input[name="username[]"]').map(function(){ 
                    return this.value; 
                }).get();

                $.ajax({
                    type: 'POST',
                    url: 'users.php',
                    data: {
                        'username[]': users,
                        // other data
                    },
                    success: function() {

                    }
                });

            });

        });
