AJAX :: Chat System Like Facebook ?
Mar 30, 2010
A lot of websites have a chat system built into them.
I assume they work something like this:
User1 enters message
AJAX posts message to server
Server holds message
User2 does ajax get to check if there is a message
If there is a message when User2 checks the server responds to the ajax request accordingly Rinse, repeat.
I guess ultimately what I am asking is there an interval set to constantly check the server? Or is there another way of doing it.

I want to make a chat system using the Comet push-style technology. I
already wrote a poll-based one using Ajax, but I want to learn how to
do server-pushes. Does anyone know of a good website that can show me
how to do this? Or recommend a good library/framework to use?

I am trying to create a private chat from hacking some opensource chat room.I am trying to use some basic AJAX (noobie) to insert a field into a mysql db.It is doing what I want it to do mysql wise but it also changes the url.
my site runs like this. There is a page called private.php with all the php in. private.php has a switch statement to call other pages (the default is home.php).so if a user say clicks contact the link would be private.php?mode=contact.and then in the private page the switch statement would
case "contact":
require("contact.php");
break;
so the user has searched another user and wants to chat.the url at the moment is private.php?mode=full_profile&id=101 in the full_profile.php page I have the ajax in the head and a submit form to call the ajax function.
here is the ajax code
<script language="javascript" type="text/javascript">
<!--
//Browser Support Code
function ajaxFunction(){
[code]....
now the mysql query runs fine. the problem I have is that when I click the submit the url changes to private.php?x=18&y=28 . (the x and y vales are different everytime I click the submit).can anyone tell me where the x and y values are coming from and also why the ajax function is changing the url as the whole point of using ajax is to avoid that.

I've just installed a chat in www.englishparis.com, and though it is working well in IE, it's not working in FF. I'm speaking about the home page. Is it because I've put the script in an iframe? To understand what I'm telling, you can try chatting from the home page, ... in IE, its smooth, it FF, nothing happens on submit.

I have created a simple AJAX chat that polls the server every 2 seconds for new messages. The messages are displayed in a div layer, and the user types new messages in a textarea, the only problem is that when a new message appears it takes the focus from the textarea so you have to keep clicking back in the textarea to keep typing. Does anyone know how I can solve this?

I have developed a php script and was wondering how to go about integrating ajax into it so it will auto refresh maybe every so many seconds or maybe after anyone submits a new line of chat.
I know there are frameworks that could be used but there are several and I am not sure where to begin.
For those that need to see it my chat script will follow.
I know its not the greatest but it serves the purpose for now..
PHP Code:

I have a simple ajax chat system that fetches and displays the messages in a div container every two seconds. Because of this behaviour, users cannot scroll through the messages in the div container as it gets scrolled to the bottom every two seconds.

Below I have a facebook login/logout script for my website. The login works fine. The AJAX requests the php file, waits for the "Success" response, and then reloads the page. The logout doesn't. Instead the browser goes to the PHP file with just the word "Success" printed on it. I've separated the xml request as a separate function but that doesn't appear to solve it either. code...

Im a bit curious about this Facebook's useful functionality. When I paste a URL on the 'What's on your mind?' box, it almost perfectly gets the body of the article. How does Facebook do this?

I am building an all AJAX site for a Facebook iFrame page and am having an issue. All the pages and what not load up dynamically just fine, but some pages use the Facebook commet system. After the AJAX has loaded the page though, the JavaScript inside does not load.
This is the Facebook comment script that I need to load inside the ajax'd content.

I've been trying to learn Ajax and have been following these tutorials:- [URL] I now have it so that in my site when a user clicks tabs the content gets loaded into an originally empty right hand div without any page refresh. However I notice that as content gets loaded into the page if you right click and view source the content is not there and the div appears empty in the source. I understand why this is but I also understand that this will make the site a lot less seo friendly which brings me to my questions:-
1.Facebook pages seem to load in their content without any page refresh at all yet it seems this is actual indexable content being loaded in live or am I wrong?
2. If this is the case that they load in actual indexable content live at such speed how can I do this because I want the content in my loaded sections to be indexable yet also want the site to flow seamlessly like facebook with no page refresh at all? Are there any examples/tutorials on this?
3. I've also noticed facebook urls change as the user switch tabs yet the page itself doesn't refresh. How can I do this too again whilst keeping th page as indexable as it would be using a regular page based layout?

Im making a fact system, and I need a refresh script, For example when someone clicks on the "next fact" button, the "div" part (where the fact is displayed) refreshes. ONLY the div part. and the javascript below is externally loaded...
List of facts!
Fact[0] = "You are born with 300 bones but only have 206 as an adult because many of your bones fuse together and make bigger more solid bones.";
Fact[1] = "The word "queue" is the only word in the English language that is still pronounced the same way when the last four letters are removed.";
Fact[2] = "Beetles taste like apples, wasps like pine nuts, and worms like fried bacon.";
Fact[3] = "In 1386, a pig in France was executed by public hanging for the murder of a child";
Fact[4] = "Scientist have believed that there are more chicken in the world than any human beings.";
Generate the facts

I'm writing a firefox addon to readout the facebook-privacysettings of an user.
[url]
There are a lot of "Edit settings" which open a dialog like this:
The HTML code looks like this:
My solution idea was to fake the ajax call like this:
I got this parameter from Firebug, and i get the same answer as the "manual"-click. It's javascript code, beginning with "for...". however the dialog doesn't open, the DOM node isn't added and i get the alert "Error! Status = 200 OK"
So I just figured: why the comlicated way with ajax, can't I somehow fake the real manual click? If someone knows a way with ajax or faking the click?

I know you can get remotely hosted Java applets that link into IRC.
You can also get Java applets that you host yourself that link into IRC.
I would prefer the second option because it is obviously more flexible with no adverts, but i am aware that it sucks up bandwidth. How much would this be, with an average of this :
once a week, 10 users in the chat room for 2 or 3 hours, typing an average amount.

I'm just looking for a brief explanation of how the DeviantArt seemingly JavaScript-powered chat communicates with an IRC server. Is it via XML sockets? Is it via AJAX? Is it via something else? I seemed to remember someone saying the JavaScript called to a hidden flash embedded in the page. If so, how does the flash communicate with IRC?
