I think it is important to mention  now that this question is over 1 year old  that Socket IO has since come out and seems to be the primary way to work with sockets in the browser now  it is also compatible with Node js as far as I know

How to Use Sockets in JavaScript HTML    There is no facility to use general-purpose sockets in JS or HTML  It would be a security disaster  for one   There is WebSocket in HTML5  The client side is fairly trivial   socket  new WebSocket  ws   www example com 8000 somesocket    socket onopen  function         socket send  hello       socket onmessage  function s        alert  got reply   s        You will need a specialised socket application on the server-side to take the connections and do something with them  it is not something you would normally be doing from a web server s scripting interface  However it is a relatively simple protocol  my noddy Python SocketServer-based endpoint was only a couple of pages of code   In any case  it doesn t really exist  yet  Neither the JavaScript-side spec nor the network transport spec are nailed down  and no browsers support it   You can  however  use Flash where available to provide your script with a fallback until WebSocket is widely available  Gimite s web-socket-js is one free example of such  However you are subject to the same limitations as Flash Sockets then  namely that your server has to be able to spit out a cross-domain policy on request to the socket port  and you will often have difficulties with proxies firewalls   Flash sockets are made directly  for someone without direct public IP access who can only get out of the network through an HTTP proxy  they won t work    Unless you really need low-latency two-way communication  you are better off sticking with XMLHttpRequest for now
