Answer 1

Did you add a url to your ajax request?

Routes

Route::get('/chat', 'ChatController@chat');

AJAX

      function update() {
        $.ajax({
           url: "/chat",
           dataType: 'html',

           success: function(responce){
               $('.message_box').html(responce);
           }
        });
    }

    $('#send_message').submit(function (event) {
        event.preventDefault();

        $.ajax({
            type: "post",
            url: "/chat",
            context: this,
            data: $(this).serialize(),
            cache: false,
            async: true,

            success: function () {
                $('#message').val('');
                update();
            },

            error: function () {
                alert('Сообщение не было отправлено');
            }
        });

    });
