我用的IE9 试了下IE8 IE7 也是一样无法连接无法emit 不知道什么原因 在firefox chrome 下都是正常的 求助 ！！！ chat.js 内容：
var express = require(‘express’), app = express(), http = require(‘http’), server = http.createServer(app).listen(8000, function(){console.log(‘server listen on 8000’)}); var io = require(‘socket.io’).listen(server);
app.get(’/’,function(req, res){ res.sendfile(__dirname+’/chat.html’); })
io.set(‘transports’, [‘websocket’,‘flashsocket’, ‘htmlfile’, ‘xhr-polling’, ‘jsonp-polling’]);
io.sockets.on(‘connection’, function(socket) { socket.on(‘msg’, function(data) { socket.broadcast.emit(‘showmsg’,data); }); socket.on(‘disconnect’, function() { // handle disconnect }); });
静态文件 chat.html ：
<!doctype html> <html> <head> <meta http-equiv=“content-type” content=“text/html; charset=UTF-8”> <title>chat test</title>
</head>
<body>
<form id="form">
message: <input type="text" id='msg' value=""/>
<input type="submit" value="send" id="send"/>
</form>
<div id="showResult"></div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io.connect(),
result = $('#showResult');
socket.on('connect', function() {
result.append($('<p>').text('Connected'));
});
socket.on('showmsg', function(msg) {
result.append($('<p>').text(msg).append($('<em>').text(' from server')));
});
$('#form').submit(function(e) {
e.preventDefault();
var msg = $('#msg').val();
result.append($('<p>').text(msg).append($('<em>').text(' from me')));
socket.emit('msg',msg);
});
</script>
</body>
