如何使用stomp.js在javascript中使用Web套接字消息？

Question

I need to consume web socket messages in Javascript using stomp.js library. 我需要使用stomp.js库在Javascript中使用Web套接字消息。

I've this code structure .... 我有这个代码结构...。

<!DOCTYPE HTML>
<html>
 <head>
   <title>Client Stomp</title>
   <script src="js/stomp.js"></script>
 </head>
 <body>
   <script>
       var urlServer;
       var topics;
       urlServer = "ws://myserver.com/ws"; 
       topics = "/topic/output.values";
       client = Stomp.client(urlServer);
       client.connect("usr" , "pwd" , connectCallBack, errorCallback);

       function connectCallBack(x) {
           client.subscribe(topics, messageCallback);
       }

       function errorCallback(x) {
         // manage connection errors 

       }

      function messageCallback(x) {
           // manage message returned 
      }
     </script>
 </body>
</html>

.... and I'm able to see messages returned in my web browser console, so something like this ... ....而且我能够看到Web浏览器控制台中返回的消息，所以类似这样的...

every 10 sec. 每10秒。

How may I consume these messages in my Javacript code? 如何在Javacript代码中使用这些消息？ For examples how may I echo the b_6300_Hz values? 例如，我如何回显b_6300_Hz值？

Any suggestions / examples will be appreciated. 任何建议/示例将不胜感激。
