與express.io聊天
[英]Chat with express.io
問題描述
我有兩個文件，一個名為index.js，另一個名為index.html。 當我按發送按鈕時，該消息沒有出現
文件index.js的代碼如下：
app = require('express.io') ();
app.http().io();
app.get('/', function(req, res){
res.sendfile('index.html');
});
app.io.on('connection', function(socket){
socket.on('chat message',function(msg) {
app.io.emit('chat message' ,msg)
});
console.log('a user connected');
socket.on('disconnect', function(){
console.log('user disconnected');
});
});
app.listen(3000);
文件index.html的代碼如下：
<!doctype html>
<html>
<head>
<title>Example of chat</title>
<style>
* { margin: 0; padding: 0; box-sizing: border-box; }
body { font: 13px Helvetica, Arial; }
form { background: #000; padding: 3px; position: fixed; bottom: 0; width: 100%; }
form input { border: 0; padding: 10px; width: 90%; margin-right: .5%; }
form button { width: 9%; background: rgb(130, 224, 255); border: none; padding: 10px; }
#messages { list-style-type: none; margin: 0; padding: 0; }
#messages li { padding: 5px 10px; }
#messages li:nth-child(odd) { background: #eee; }
</style>
</head>
<body>
<ul id="messages"></ul>
<form action="">
<input id="m" autocomplete="off" /><button>Send</button>
</form>
<script src="https://cdn.socket.io/socket.io-1.2.0.js"></script>
<script src="http://code.jquery.com/jquery-1.11.1.js"></script>
<script>
var socket = io();
$('form').submit(function(){
socket.emit('chat message', $('#m').val());
$('#m').val('');
return false;
});
socket.on('chat message', function(msg){
$('#messages').append($('<li>').text(msg));
});
</script>
</body>
</html>

改寫這個
var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);
server.listen(3000);
app.get('/', function (req, res) {
res.sendfile('index.html');
});
io.on('connection', function (socket) {
socket.on('chat message', function (data) {
socket.broadcast.emit('chat message',data);
});
});
Express.io和Android
