How to get the websocket close code with atmosphere.js

[huajingze]

Our project use atmosphere.js , now I could get the response code is 200 from the "onClose" function. Request.onClose(Response) {}

how to get the specified close code from the onClose function, such as 1000 or 1001. Because I need to recoginze whether the browser close the websocket or the server side close the websocket.
Thanks much.
