AUDIENCE:   Developers who wish to write dynamic, interactive applications in Javascript. PREREQUISITES:   Some knowledge of HTML coding is essential. Previous experience of programming, especially object-oriented or 'visual' programming, would be useful but is not essential. DURATION:   2 days. Hands on. OBJECTIVES:   JavaScript is a programming language designed to make HTML more dynamic and interactive. This course aims to show you how JavaScript interacts with the various HTML elements, including forms, frames, images and other embedded objects, and the main browser window. With the techniques learned on this course delegates will for example be able to make mouse 'rollovers', validate forms before they are submitted and control the main browser window.
