Question

How to create flashing title effect like facebook? Means, when you are chatting with someone and a new message is received, a title starts to switch between the original tit

Answer 1

Set an interval that switches the title every few seconds. Untested code:

function flashTitle(pageTitle, newMessageTitle)
{
    if (document.title == pageTitle)
    {
        document.title = newMessageTitle;
    }
    else
    {
        document.title = pageTitle;
    }
}

setInterval("flashTitle('Facebook', 'New message from John Doe!')", 800);

Answer 2

setInterval("var x='www.WHAK.com/Packer/',y='WHAK.com/Packer/',z=document;z.title=z.title==x?y:x",900);

Answer 3

Code:

(function () {

var original = document.title;
var timeout;

window.flashTitle = function (newMsg, howManyTimes) {
    function step() {
        document.title = (document.title == original) ? newMsg : original;

        if (--howManyTimes > 0) {
            timeout = setTimeout(step, 1000);
        };
    };

    howManyTimes = parseInt(howManyTimes);

    if (isNaN(howManyTimes)) {
        howManyTimes = 5;
    };

    cancelFlashTitle(timeout);
    step();
};

window.cancelFlashTitle = function () {
    clearTimeout(timeout);
    document.title = original;
};

}());

Usage:

flashTitle("New Message from Matt Lunn");

... or...

flashTitle("New Message from John Smith", 10); // toggles it 10 times.
