Notificon is a BSD licensed javascript class for providing client-side favicon notifications. Instead of requiring a number of favicons be created and served up to the client, you can specify a label and a favicon (default being the current favicon) and it will generate a favicon notification.
Due to browser limitations, Favicons can only be changed post-render in Chrome 6+ and Firefox 2+ and Opera. Other browsers are currently unsupported.
- Include the notificon.js in your page
- Call Notificon(12) to overlay the number 12 on your favicon.
Notificon can take 2 parameters - Notificon(label, favicon_url) where label is the text to overlay, and favicon_url is the url of a 16x16 favicon.
An empty label will clear your favicon to its original state. e.g. Notificon();
Favicon_url defaults to your primary favicon (if specified in head, or with fallback to /favicon.ico)
