多个浏览器中的页面标题通知

Question

I have a chat script on a webpage. Now, when someone adds a message I want to notify other people who have the page/tab open but not active, to receive a notification of a new message.
For instance, I would like to change the page title from 'Chat' to 'New message - Chat'. I think this is what 'Facebook Chat' does too.

But when I use: document.title = "New Message"; It only changes in the browser of the user that submitted the message. Not on the other browsers.

How can I achieve this?

Answer 1

You can give your title an id:

document.getElementById("title").innerHTML ="new Title";

or simply

document.getElementsByTagName('title')[0].innerHTML = "New Title";

either way it will work

UPDATE:

after rereading i made a mistake i see.

when your script check for a new message, if there is a new message you should change the title also, or perform additional test to see if there the user is active or not before changing the title
