當我發送消息時，Socket.io聊天應用程序刷新

我正在嘗試使用Node.js，socket.io和express來創建一個簡單的聊天應用程序。但是，如果我單擊main.jade文件中的發送按鈕，頁面將刷新，並且不會顯示任何消息。我在Firebug也出現此錯誤：當我發送消息時，Socket.io聊天應用程序刷新

到WS連接：//127.0.0.1：3000/socket.io/EIO = 2 &運輸= WebSocket的& SID = d_hNMPdXHed-j7LrAAAH中，而頁面中斷？正在加載。

      $('#m').val('');

看起來該頁面正在被重新加載，因爲您忘記了將您的客戶端js代碼與$(document).ready(function() { ... });
