Introduction to JavaScript

This two-day course is designed for HTML authors and Web designers who wish to add dynamic and interactive content to their pages using client side scripting with JavaScript. Routines will be developed which can provide feedback to users, create pop up dialog boxes, validate forms, and provide customised content. Delegates will leave with programs that will work with all browsers in common use today.

Delegates must have a good knowledge of HTML, and be experienced Internet users. No prior programming experience is assumed. For delegates without HTML knowledge, an Introduction to HTML course is available. An Advanced JavaScript course is also available.
