Interenet Applications In Javascript

This seminar will focus on the core language of JavaScript, not on fancy DHTML effects like layers and animation; however, a better understanding of JavaScript does makes it much easier to write cleaner and more reliable DHTML. Participants will also explore error handling and object oriented programming, and look at examples of how this can improve their code. They will also look at ways of talking directly to the server from JavaScript, which will allow the development of more responsive, user-friendly applications. Object Oriented Programming Primer Object oriented programming versus procedural programming Elements of object oriented programming Classes Objects Methods Properties Object Oriented Programming in JavaScript Prototype language versus a true object-oriented language Creating objects in JavaScript Creating methods in JavaScript How do objects relate to document objects? Why bother creating our own objects in JavaScript?
