Purpose of this course

The course is intended to continue where our HTML/CSS course left off, looking to enhance static webpages with JavaScript to shape and modify content on-the-fly. Emphasis is placed upon code maintainability and testing/debugging. This content also serves as a good grounding for techniques visited on our .NET courses.

Who is this course for

The content is aimed at anyone who has to maintain or modify a web site. Whatever technology you use at your workplace, JavaScript, jQuery, AJAX and JSON will almost certainly play a large part in your company web site. Having staff members trained in these technologies means you can quickly and easily make adjustments that would otherwise have to be done by expensive contractors.

You will learn how to
  • Produce more dynamic web pages that react to user actions
  • Manipulate web content interactively
  • Write browser-based applications for cross-platform web delivery
Benefits for your organisation

Many web pages written to older standards will show signs of failing in newer browsers. It is important that modern websites are written to correct standards not just for compliance and maintainability reasons, but to prevent loss of credibility and/or lost sales. Imagine where ebay, amazon, google or facebook would be if they failed to keep up with web standards - how would loss of functionality impact your business?

Benefits for you as an individual

As a developer these days, it’s a pre-requisite that you know these core technologies of JavaScript, jQuery, AJAX and JSON. Once these are mastered, you will better be able to troubleshoot and debug existing site functionality. Plus, the added bonus of being able to jazz up any websites, whether corporate .NET pages or a personal website – JavaScript/jQuery/AJAX can do so much.
