客户端代码：
1 <html> 2 <head> 3 <script> 4 var socket; 5 if ("WebSocket" in window) { 6 var ws = new WebSocket("ws://127.0.0.1:8181"); 7 socket = ws; 8 ws.onopen = function() { 9 console.log('连接成功'); 10 }; 11 ws.onmessage = function(evt) { 12 var received_msg = evt.data; 13 document.getElementById("showMes").value+=evt.data+" "; 14 }; 15 ws.onclose = function() { 16 alert("断开了连接"); 17 }; 18 } else { 19 alert("浏览器不支持WebSocket"); 20 } 21 function sendMes(){ 22 var message=document.getElementById("name").value+":"+document.getElementById("mes").value; 23 socket.send(message); 24 } 25 </script> 26 </head> 27 28 <body> 29 <textarea rows="3" cols="30" id="showMes" style="300px;height:500px;"></textarea> 30 <br/> 31 <label>名称</label> 32 <input type="text" id="name"/> 33 <br/> 34 <label>消息</label> 35 <input type="text" id="mes"/> 36 <button onclick="sendMes();">发送</button> 37 </body> 38 </html>

注：需先引入Fleck包
