Javascript Desktop Notifications

I'm not gonna write massive paragraphs about his one, but simply provide a nice example of how to implement desktop notifications for browsers running webkit in JavaScript. Who knows maybe Internet Explorer will support it some time soon?

Here's my useful function that should let you easily post notifications to the user, it includes an onclick handler and auto focuses the window on click too.

var Site = {};
Site.Notifications = {
    GainAccess: function (callback) {
        if (Notification.permission !== "granted") { 
            Notification.requestPermission(callback);
        }
    },
    Notify: function (title, message, imageAddress, onclick) {
        var notification = {};

        // Let's check if the browser supports notifications
        if (!("Notification" in window)) {
            //alert("This browser does not support system notifications");
            return;
        }

        // Let's check whether notification permissions have already been granted
        else if (Notification.permission === "granted") {
        // If it's okay let's create a notification
            notification = new Notification(title,
            {
                icon: imageAddress,
                body: message,
            });
        }

        // Otherwise, we need to ask the user for permission
        else if (Notification.permission !== 'denied') {
            Notification.requestPermission(function (permission) {
                // If the user accepts, let's create a notification
                if (permission === "granted") {
                    notification = new Notification(title,
                    {
                        icon: imageAddress,
                        body: message,
                    });
                }
            });
        }

        // Add callback when notification is clicked.
        notification.onclick = function () {
            // Show user the screen.
            window.focus();

            // Close notification.
            notification.close();

            // Perform requested action.
            if (onclick != undefined && onclick != null) {
                onclick();
            }
        };
    }
}

Then you simply call it using the code below:

Site.Notifications.Notify("Hello world", "How you doin?", "http://linktomyimages.com/image.png", function () { alert ("You clicked my notification!") });

That's it.
