Google Gears (BETA) is an open source browser extension that enables web applications to provide offline functionality using following JavaScript APIs

You can mark resources as being available offline. This is an interesting feature that doesn't, yet, have a specification-home (although, some suspect that it'll be adopted by the WHATWG). It provides the ability, for the user, to specify individual resources for special caching, should the browser move into offline mode.

This extension provides a menu option on the Tools menu for opening the Java Console from Firefox. It also provides a toolbar button in the JavaScript Console for loading the Java Console.

This javascript class allows you to add window in a HTML page. This class is based on Prototype. The code is inspired by the powerful script.aculo.us library. You can even use all script.aculo.us effects to show and hide windows if you include effects.js file , but it's not mandatory. It has been tested on Safari, Camino, Firefox and IE6, Opera looks fine.

SmilScript is a library intended for use by authors or publishers of SVG documents. SVG uses an extended subset of SMIL to achieve declarative (element-based, non-scripted) user interaction and animation events. This library is not intended to be used outside the context of SVG and its limited subset of SMIL, so it probabaly isn't appropriate for other SMIL content. It also will not work for Firefox builds that do not include the native SVG viewer (version 1.5 or later).

In this third article of the XML in Firefox 1.5 series, you learn to manipulate XML with the JavaScript implementation in Mozilla Firefox. In the first two articles, XML in Firefox 1.5, Part 1: Overview of XML features and XML in Firefox 1.5, Part 2: Basic XML processing, you learned about the different XML-related facilities in Mozilla Firefox, and the basics of XML parsing, Cascading Style Sheets (CSS), and XSLT stylesheet invocation.

Alors que la plupart des extensions rajoutent des fonctionnalités à votre navigateur, Greasemonkey permet d’agir, et c’est là toute son originalité, directement sur la page web que vous visitez grâce à des scripts javascript, ou des blocs DHTML si vous préférez.

Vous avez certainement pu voir la démo de l'horloge codée avec la technologie Canvas. Voici ce même exemple mais codé avec d'autres technologies. Comment fonctionne l'application originale ? Elle utilise une balise nommée <canvas/> qui permet de dessiner en Javascript. Conrètement, il y a un dessin pour le fond de l'horloge, et un dessin pour chaque aiguille. Via un code javascript du <canvas/>, les positions des aiguilles sont mises à jour. Le fait de pouvoir bouger l'horloge sur la page est une mise à jour des coordonnées du <div/> qui embarque l'horloge. C'est une jolie démo qui montre comment utiliser Canvas et ce que l'on peut en faire. René-Luc D'Hont vous propose exactement la même démo mais avec 2 autres technologies, le SVG et XBL. Ces démos ne sont visibles que sous Firefox 1.5.
