Question

我最近能够在浏览器和服务器之间建立连接..但是过去两天连接没有建立......我无法弄清楚出了什么问题？

<head>
<script type="text/javascript">
function WebSocketTest()
{
 if ("WebSocket" in window)
 {
   var x=document.getElementById('chat').value;
   // Let us open a web socket
   var ws = new WebSocket("ws://localhost:7869/echo");
   ws.onopen = function()
   {
    // Web Socket is connected, send data using send()
    ws.send(x);
    var send=document.getElementById('fill');
    send.innerHTML = send.innerHTML+'<br>'+ x;
   };
   ws.onmessage = function (evt) 
   { 
    var received_msg = evt.data;
    var send=document.getElementById('fill');
    send.innerHTML = send.innerHTML +'<br>'+ received_msg;
   };
   ws.onclose = function()
   { 
    // websocket is closed.
    alert("Connection is closed..."); 
   };
  }
  else
  {
    // The browser doesn't support WebSocket
   alert("WebSocket NOT supported by your Browser!");
  }
}
</script>
</head>
<body>
<div id="sse">
 <input type="text" id="chat"></div><br>
 <button type='submit' onclick='javascript:WebSocketTest()'>Send</button>
<div id='fill'>hi</div>

</body>

这是代码和websocket服务器正在监听7869端口。
