Slashdot/Solidot报道： http://it.solidot.org/article.pl?sid=09/12/11/0315211&;from=rss

Web Sockets Now Available In Google Chrome
例子：

1. if ("WebSocket" in window) {
   
2. var ws = new WebSocket("ws://example.com/service");
   
3. ws.onopen = function() {
   
4. // Web Socket is connected. You can send data by send() method.
   
5. ws.send("message to send"); ....
   
6. };
   
7. ws.onmessage = function (evt) { var received_msg = evt.data; ... };
   
8. ws.onclose = function() { // websocket is closed. };
   
9. } else {
   
10. // the browser doesn't support WebSocket.
    
11. }

W3C WebSocket标准中的WebSocket 接口

1. [Constructor(in DOMString url, in optional DOMString protocol)]
   
2. interface WebSocket {
   
3. readonly attribute DOMString URL;
   
4. 
   
5. // ready state
   
6. const unsigned short CONNECTING = 0;
   
7. const unsigned short OPEN = 1;
   
8. const unsigned short CLOSED = 2;
   
9. readonly attribute unsigned short readyState;
   
10. readonly attribute unsigned long bufferedAmount;
    
11. 
    
12. // networking
    
13. attribute Function onopen;
    
14. attribute Function onmessage;
    
15. attribute Function onclose;
    
16. boolean send(in DOMString data);
    
17. void close();
    
18. };
    
19. WebSocket implements EventTarget;
