In this column we introduce DOCJSLIB Version 2.0. This version is an expansion of DOCJSLIB Version 1.0 which we introduced in our last column. Version 1.0 included three basic functions and handled creation and manipulation of a clickable DIV/A/IMAGE DHTML element. Version 2.0 includes nine functions and supports a DIV/HTML box element as well.

Version 2.0 goes a long way towards providing neophyte programmers with a cross-browser infrastructure that eases a lot the DHTML application programming. Object-oriented programming principles are religiously kept, ensuring a clean Procedural Interface (API-like) between the user's application and the library's nuts and bolts. In this column, we demonstrate easy application authoring with our popout elements from column 14, Pop-out Elements. Be sure to read this column for comparing the non-library version and the current DOCJSLIB-based version.
