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;
};
}());
