jQuery chat application

Question

I'm writing a chat application as part of a project which is a sort of IRC/forum crossover in the sense that the chat updates in realtime but the feed is saved in my MySQL database.

This is only my second time using jQuery and I just wanted to check I'm on the right lines before I start researching further.

So this calls the jQuery function:

<form id="chatform" action="javascript:get();">
<input type="text" id="chatbox" name="chatbox">
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/chat.js"></script>
</form>

My PHP should:

Find all the variables (User ID, timestamp, message etc).
Input these values into the database.
Echo a all of the chat messages with everything correctly aligned.

My jQuery should:

Display the new message in realtime by fading in: element.fadeIn(500);

Is this all good or am I missing anything?

How do you plan to update the other chat clients with the new message? — Raynos, Jun 11 '11 at 15:25
This is one issue I had anticipated, is there an easy workaround for it? — Sebastian, Jun 11 '11 at 15:29
bi directional communication, i.e. WebSockets or COMET. Take a look at [`now`](http://nowjs.com/). [Similar question](http://stackoverflow.com/questions/6304937/how-to-get-realtime-updates/6304975#6304975) — Raynos, Jun 11 '11 at 15:34
Would it be very silly to have an auto-update of the chat window every second or so? — Sebastian, Jun 11 '11 at 16:15

I don't konw where your messages is saved.Is it be put in mysql.I don't think is a good place.Since that this messges may be useless after this time . and I think it should be seperated into two parts ,one is show messge ,and second is to tranfet message. the first is to get message from the back every some time. and the transfer part only work on the time you click the sending button.
