1、先安装npm和node
2、安装socket.io
npm install socket.io
3、html
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Ssocket</title>
<script src="http://localhost:8088/socket.io/socket.io.js"></script>
</head>
<body>
<div></div>
<input type="text"/>
<button>button</button>
<script type="text/javascript">
var input = document.getElementsByTagName("input")[0];
var button = document.getElementsByTagName("button")[0];
var div = document.getElementsByTagName("div")[0];
var socket = io.connect('http://localhost:8088');
var data;
socket.on('news', function (data) {
div.innerHTML=data.my;
console.log(data);
});
button.onclick=function(){
socket.emit('my other event', { my: input.value });
};
</script>
</body>
</html>
4、js
/**
* Created by zcwl123 on 2017/5/9.
*/
var app = require('http').createServer(handler),
io = require('socket.io').listen(app),
fs = require('fs')
app.listen(8088);
io.set('log level', 1);//将socket.io中的debug信息关闭
function handler (req, res) {
fs.readFile(__dirname + '/index.html',function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Error loading index.html');
}
res.writeHead(200, {'Content-Type': 'text/html'});
res.end(data);
});
}
io.sockets.on('connection', function (socket) {
socket.emit('news', { hello: 'world' });
socket.on('my other event', function (data) {
io.sockets.emit('news', data);
console.log(data);
console.log(1);
});
});
5、启动server.js
node server.js
6、其余api参考
