A system and method for generating high-function browser widgets with full addressability are provided. With the system and method, custom JSP tags are utilized that generate JavaScript objects to provide the high-function browser widgets. The JavaScript objects, in turn, output HTML for use by a client side Web browser. These JavaScript objects have instance-level functions or actions that are encapsulated in the widget as well as a complete client-side model representation of the data also encapsulated in the widget object. These objects and actions are fully addressable by the developer via a getWidgetByID method on a global utility object. As a result, higher-level features and full inter-widget communication are achievable using the custom JSP tags of the present invention.
