How to send a UDP package in browser using HTML5 or WEBRTC?

I want to send an UDP package to my UDP server in browser. I heard that HTML5 or WEBRTC can do something, but I don't know how.

Can someone help me?

You could either write a chrome extension (app) which would give you access to https://developer.chrome.com/apps/sockets_udp ("sockets": {...} in your manifest.json).

Or, as far as WebRTC goes:

var pc = new webkitRTCPeerConnection(
    { "iceServers": [{ "url": "stun:localhost:1234" }] }
);

pc.createOffer(function (sessionDescription) {
    pc.setLocalDescription(sessionDescription);

}, function(error) {
    alert(error);
}, { 'mandatory': { 'OfferToReceiveAudio': true, 'OfferToReceiveVideo': true } });

You'd then able to get the UDP packets on localhost:1234 via:

$port = 1234

t = Thread.start do
  server = UDPSocket.open
  server.bind(nil, $port)
  a = server.recvfrom(12364)
  puts server.send "ping", 0, a[1][2], a[1][1]
end
t.join
