Fundamentals of JavaScript

Objectives

A two-day course for HTML authors and Web designers who want to add dynamic and interactive content to their pages using client-side scripting with JavaScript. The course includes routines to create pop-up dialog boxes, validate forms and provide customised content. The course is available to users of both Macintosh and PC platforms and delegates will leave with complete programs that can be used on their own sites.


Pre-requisites:

Ideal delegates are HTML authors with at least one site under their belts and strong knowledge of HTML. Knowledge at least equivalent to, Transmedia's two-day Introduction to Web publishing course is essential - JavaScript is intellectually challenging!


Course Includes:

A comprehensive set of reference notes covering course topics, follow-up telephone support and, for training on Transmedia premises, lunch and refreshments.
