看看W3C在HTML5里对于WebSocket的接口定义：
 
interface WebSocket {  readonly attribute DOMString URL;  // ready state  const unsigned short CONNECTING = 0;  const unsigned short OPEN = 1;  const unsigned short CLOSED = 2;  readonly attribute unsigned short readyState;  readonly attribute unsigned long bufferedAmount;  // networking           attribute Function onopen;           attribute Function onmessage;           attribute Function onclose;  boolean send(in DOMString data);  void close();};WebSocket implements EventTarget;
