如何像Facebook一樣創建標題提醒效果？

Question

如何像facebook一樣創建閃爍的標題效果？ 意味着，當您與某人聊天並收到新消息時，標題開始在原始標題和消息之間切換，通知用戶新消息的到達會產生閃爍效果。

AdrianoKF的解釋：

注意窗口標題在收到新聊天消息后在“Foo Bar的新消息”和常規消息之間循環。

Answer 1

碼：

(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;
};

}());

用法：

flashTitle("New Message from Matt Lunn");

... 要么...

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

Answer 2

設置每隔幾秒切換標題的間隔。 未經測試的代碼：

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 3

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