Question

我需要使用stomp.js库在Javascript中使用Web套接字消息。

我有这个代码结构......

-keep

....我可以在我的网络浏览器控制台中看到返回的消息，所以像这样......

<!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>

每10秒钟一次。

我如何在Javacript代码中使用这些消息？例如，我如何回显b_6300_Hz值？

任何建议/示例都将受到赞赏。
