[jQuery] Re: comet long polling with jquery
hello,
I finally got my server to run an example comet application, which
uses the long polling method.
The example code I got uses prototype library, which i dont want to
use. I understand there is a comet plugin for jquery that supports the
bayeux protocol, which is not what I want.
Searching in this group, I have read that the long pollling method
does not require a plugin, and just the standard ajax methods are ok.
What I need to do shortly, is to submit an ajax request, (which will
only be replied when the server sends data) when the server sends data
(it sends success in the body, and json data in the response header),
the ajax method must process the json data, and restart itself making
another ajax request. also, this ajax request should start at document
ready.
Any ideas?
Best,
-C.B.
This should get you started:
(function($) {
$(document).ready(startComet);
function startComet() {
$.ajax({
url: 'myCometServer.php',
complete: onComplete
});
};
function onComplete(xhr, status) {
if (status == success) {
var json = xhr.getResponseHeader('myCometHeader');
$.globalEval('('+json+')');
startComet();
}
else {
// handle errors
}
};
})(jQuery);
[jQuery] Re: Comet Technique - possible with jQuery? Plugin?
Thank you! With the Bayeux implementation, what will that allow me to do? I am already using ajax calls in my page to get my words and to keep the x/y for each element, you can see by going to the site. Then a comet server? What is the real advantage there?

[jQuery] Re: Comet
Great, I've been doing some Comet last year for a project. It's great
but really geeky for some people, so developping a plugin around that
sounds just great to me :).
I'll check the work asap!

I have been working on implementing the Bayeux protocol in jQuery and with
the recent talk on the list about LIVE ajax and server pushing I thought now
would be a good time to release the early work and start getting some
feedback. It will work on Jettys Cometd Echo Demo. To get it to work, remove
all the dojo scripts, and jquery and this plugin. In your on ready add
$.comet.init('/cometd'). Bind a listener to an element listening for
'/service/echo' and publish ($.comet.publish) a message to the echo service
$.comet.publish('/service/echo', {msg: 'what ever message'}). The second
param of the event trigger will be that data return from the Cometd server.
Subscriptions are a bit shaky at the moment, I am rewriting the chatroom
demo to ensure it is working. Check out the code

[jQuery] Re: Comet calls/multiple open HTTP connections
David, I'm using jQuery 1.2.1 (I love it... the selectors are most awesome and it has a very functional flavor) I've got a situation that I've seen on Firefox 2.0 (it may be an issue on other browsers.) It seems that I can only have 2 pending HTTP requests from the browser to the same server at a given time. Firefox has configuration settings that limit the number of concurrent connections to servers as well as to per server. Here's a blog entry with more information: http://prefetch.net/blog/index.php/2005/01/20/speeding-up-firefox/ Make sure to read the section on network.http.max-persistent-connections-per-server, which defaults to 2. -Dan

it seems that the comet plugin doesn't run correct with ie7.
When i watch the demo at:http://empireenterprises.com/_comet.html
with FF
there are messages like {idx:1,message:}, {idx:2,message:}
and so on.
with ie7 only the message {idx:1,message:} appears.
