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?
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 have a shopping cart where if a user have problems of buying products or transactions, I want to give support via a chat programme. I want to reply users in different chat threads not like in a chat room as other people dont want to see others chat.I am new to this subject.
View 3 Replies View RelatedI 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 been reading a lot about Comet and I've been interested in implementing it. It doesn't sound that difficult, but I have yet to find concrete examples of what it is, so I don't know how to actually use it.
I've seen some examples where new ajax requests are made as soon as old ones are complet but this doesn't make any sense to me. It seems this method is a complete resource bandit.
For example, how do I open a long-lived HTTP request? If the request is long-lived, when does the callback get actually called - at the very end of the request (status == 200 and readyState == 4) or can I call it intermittently to download new data while my PHP script is in sleep()-ing?
I want to know whether I can find out the MAC address of the system which is accessing my website.
Is there any way to do this using javascript.
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?
View 2 Replies View RelatedI 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..

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.

I have gone through the basic techniques to implement comet server like streamhub,Maven/Jetty etc. I have following questions for that :
After that I found the issues like in case of Maven/Jetty internet connection is required for downloading certain files from net.So it it possible to implement it if no internet connection is there on machine where the web server is hosted ?
Also I want the open source tools/technologies to achieve the thing mentioned in the above question. and I think stream hub is not a open source free version. which is free/open source to use.
Currently the web application is running on apache web server. so if I use comet server what changes I need to do in that ?
Anyone with an ajax/php online voting system? Or do you know some popular site i could get it from?
View 1 Replies View RelatedIm 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.";

I'm a AJAX newbie, I was wondering if I can use the .responseText method, to load the text from other website? For example, how can I download the data from "[URL]" and display the data in my own way? It seems that the .responseText/.responseXML does not work here...

View 2 Replies View RelatedI have a login panel on my website that is implemented as an overlay div. So if the user clicks on a link that requires authorization, this div is made visible with javascript. In the login panel there is a form consisting of a field for the user name, the password and a submit button. What I want to do is when the user entered his name/password and clicked on submit I want to do an asynchronous request and check whether the password was correct.
My question now is: What is the best way to do this check? Intuitively I would create a response xml file where I store a variable like <correctPassword>1</correctPassword> and check whether this variable is 1 (true) or 0 (false) and react accordingly.
Is that the way to go or is there a better approach to achieve this?
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.
how is it possible to backdoor a java based chat room?

View 2 Replies View RelatedI'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?
