Click the profile, it opens in new window as usual

Click on the down arrow button in the top right corner of the window, and you can see Go off the record link there.

And type any chat, say “hi”

You will get a red text showing the “person is offline , can’t receive the message right now ” implies the  person is offline

If this message does not appear, it means the user is invisible

Today i implemented gmail chat window , not an ajax chat with a chat server, but its client side implementation.

Here you can see the demo: http://www.sajithmr.com/gtalk/

Take this link in a new tab or window, and take any other website without closing it.

After 3 seconds , (Consider it as a new chat message arrived situation) you can see the google chat notification sound , and title changing. (I didn’t get the actual gtalk notification sound, so i used windows notify.wav file )

You know google (gmail) implemented its sound notification is via swf object. Here me too done the same.

I wrote two function to check whether the browser is in focus or not.

Here is the functions:

function lostFocus()
{
document.title = 'Sajith M.R Says...';
state = 'nonfocus';

played =  0 ;

changeColorRed();

alterTitle();

}

function gotFocus()
{
document.title = 'Gmail Inbox(1)';

state = 'focus';

played = 0 ;
}

The alterTitle() function calls in 3 seconds setTimeOut manner.

function alterTitle()
{

if(state =='nonfocus')

{
if ( document.title == 'Gmail Inbox(1)')
{

if(played == 0)
{
soundManager.play('notify');
played = 1;
}

document.title = 'Sajith M.R Says...';

}
else
document.title = 'Gmail Inbox(1)';

setTimeout("alterTitle()",3000);

}
}

The soundmanager.js file handles the swf flash object and sound triggering.

<script type=”text/javascript” src=”script/soundmanager.js”></script>

These three simple scripts together created this demo: http://www.sajithmr.com/gtalk/
