Ajax

Asynchronous JavaScript And XML, or its acronym, Ajax (Pronounced A-jacks), is a Web development technique for creating interactive web applications. The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire Web page does not have to be reloaded each time the user makes a change. This is meant to increase the Web page's interactivity, speed, and usability.

Editable HTML Content

One of the little known features of DHTML, at least within Internet Explorer 5.5 or above, is an attribute known as contentEditable. This attribute can be used to make areas of text within a Web page editable by the user. This is very different from a form element, such as a text box, as contentEditable can make a table cell, or a standard paragraph editable.

Quick and Dirty Web Applications with Bookmarklets

Web 2.0 is well known for the fact that it's not built on breathtaking new inventions, but rather on renewed emphasis on age-old Web technologies. One of those age-old technologies that is enjoying a revival in Web 2.0 is bookmarklets. A bookmarklet is essentially a Web application shoehorned into a regular browser bookmark. This article includes a fully functioning bookmarklet and installation instructions you can use to highlight text on any Web page and search IBM developerWorks for that text.

Understanding Java  

This paper introduces neophytes to Java. It starts with Java’'s beginnings as a programming language for interactive cable TV boxes and continues through the features of optimization, platform-independence, and object-orientation that make it unique. Next, it dispels the myths surrounding Java, presents solid guidelines for when and when not to use Java, and finally examines today’s practical uses of Java, including enhancing Web pages, managing a business, and delivering sophisticated training modules capable of advanced interactions.

User Annotations in Ajax  

The ability to add notes and comments to your Web site can be a powerful and attractive feature for users. This tutorial demonstrates how to implement an Asynchronous JavaScript and XML (AJAX)-based user annotation system in the form of yellow sticky notes that sit on top of regular Web page content. The only additional, required configuration is a back-end Perl script that stores the annotations.
