Chat Program - Controlling Scroll Of DIV
Feb 26, 2010
I am trying to make a chat program, and now I want the div to scroll down (entirely down), if the scroll bar already is at the bottom, when the text changes. So Here is the test page. Notice the little debugging area at the bottom. You see that when you scroll the DIV (with message story) entirely down, the scrollTop and scrollHeight does not match, so how, exactly, do I check if the scroll is at the bottom? Notice that if the server is down, or if you don't see what I am explaining, try to refresh the page, or wait a little and then refresh.

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.

The problem I'm trying to solve is that the
designer would like to limit the total number of entires shown when
you click on the drop-down arrow of a select box. I'm starting to
think that this isn't possible.
I've tried the following with no luck:
- Setting the height attribute on the select element
- Setting a style height for the select attribute
- Modifying the same through Javascript
- Setting the style overflow-y to scroll
- Setting the size of the select element
At some point in my browsing someone claimed that the vertical scroll
bars are controlled by the OS/Browser and there are no ways to change
this using JS or CSS. That the magic number of IE is 30 entries before
the vertical scroll bar shows up.

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 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?

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..

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.

As someone who has a web site, there is this popup (not my own) that comes
up that I can't make go away when others view the page. Is there anyway,
at least, to make sure that the parent window supersedes and is the top
lawyer vs. this smaller pop-up using javascript?
