需要使用这里的插件：

https://github.com/Automattic/socket.io/issues/1204 https://github.com/mkuklis/phonegap-websocket https://bitbucket.org/mkuklis/phonegap-websocket-demo 不幸的是这个插件不能直接在worklight6.1中使用。 （尽管worklight6.1是基于cordova3.1做的封装<==通过在js中alert(device.cordova)中可以直接看出来），但是在worklight中不能直接使用cordova的插件，这点很不爽） http://socket.io/socket-io-with-apache-cordova/ http://www.blogjava.net/yongboy/archive/2012/05/10/377787.html 其它碰到的问题：

http://www.giantflyingsaucer.com/blog/?p=2535 以下代码在android上打印出ReferenceError: io is not defined，mobile app到底是否支持socket.io client

$(document).on("pageinit","#chatroomPage",function(res){	console.log("chatroom page init.");	try{		var socket = io.connect('http://192.168.1.101:3000');		socket.on('connect', function(data) {			console.log("connected to chat server.");			socket.on('chat message',function(msg){				$("#incomingMessages").append("
    
     " 						+ msg.user + ": " + msg.msg + "
    
");		        $("#incomingMessages").scrollTop($("#incomingMessages")[0].scrollHeight);			});		});				socket.on('error', function(data) {			console.log("error connect to chat server.");		});		socket.on('disconnect', function(data) {			console.log("you are disconnected from chat server.");		});				$('#btnSend').bind('click',function(){			socket.emit('chat message', {user:loginUser,msg:$('#m').val()});			$('#m').val('');			return false;	        });			} catch (e){		navigator.notification.alert("socket.io error:" + e);		console.log("socket.io error:", e);	}});

而在simulator上正常
