  overflow-y: scroll;
  background-color: #f5f5f5;
  padding: 10px;
}

    var message = $('.chat-input input').val();
    if(message != ''){
      $('.chat-box').append('
用户消息
');
      $('.chat-input input').val('');
      $('.chat-box').scrollTop($('.chat-box')[0].scrollHeight);
    }
  });
  
  // 回车键发送消息
  $('.chat-input input').keypress(function(event){
    if(event.which == 13){
      $('.send-button').click();
    }
  });
