Abstract: An internally consistent system implementing object-oriented programming constructs in ECMAScript is described. First, a function, rather than the ECMAScript new keyword, is used to initiate new instance creation. The instance creation function is assigned to a non-Function instance rather than an instance of Function as required for use of new. Instances with attached instance creation functions serve as “type proxy” objects and replace the Function instances normally used as types. Since the type proxies and prototype chains created and maintained by the invention are instances of normal objects, rather than instances of Function as required by standard ECMAScript, this approach allows native ECMAScript lookup semantics to be leveraged while supporting inheritance of both state and behavior for instances and types to any level desired.

Abstract: A system implementing unified and extensible event handling in ECMAScript is described. The current capturing, bubbling, and DOM Level 2 systems of UI event handling are unified without requiring upgraded or altered browsers by leveraging JavaScript to create data structures and processes which capture and realign these disparate systems of event handling. Object dependency is supported through the same unified event system which resolves the differences between capturing, bubbling, and DOM Level 2 event models while integrating non-UI and distributed event support resulting in a system capable of supporting MVC patterns. The particular advantage of the described system is that the implementation is in JavaScript and requires no applets, plugins, or other alterations to currently deployed web browsers.
