The method for getting information through an implicit request can be applied not only for technical dictionary. Have you ever wondered about the double underlined links in such projects as hotscripts.com and devarticles.com? This is context-dependent advertising based on IntelliTXT engine from Vibrant Media (www.vibrantmedia.com). When the mouse cursor points to such a link an advertisement window appears. This technology is referred to as in-text advertising.
This method is also increasingly used on news portals. The main page contains only the news headings. Yet when the user puts a mouse cursor over the heading a short description appears. Thus the main page can hold a lot more news. The visitor sees the headings and all he/she has to do to get a short summary is to browse through the items with a mouse cursor. Let us now look into how contextual help can be implemented with AJAX.
AJAX allows you to make a call to an http server (typically an RSS feed or a webpage), get it’s content and load them into your existing page without having to refresh the whole page. This means that services like email don’t have to reload the whole page everytime you click a message, saving on bandwidth (loading the header/footer all over again) and making things more efficient.
CAPTCHA has become a popular means of securing forms against automated submission, by requiring users to enter a string displayed in an automatically generated image.
This implementation uses Ajax to conveniently combine CAPTCHA into normal pre-submission form verification. You'll need PHP to be installed with the GD image library (most PHP implementations will have this as standard).
