HTML5 for Flash Developers

By: Matthew Fisher

Overview of this book

As the support for HTML5 within modern web browsers grows, the appeal of HTML5 development, especially for Flash developers, is at an all-time high. From 3D interactive multi-user content to high definition video streaming, HTML5 can deliver it all, to almost all modern web browsers, desktops, and mobile platforms. HTML5 for Flash Developers is a practical, targeted guide for developers with previous experience in developing applications in Flash who would like to add HTML5 development to their skill set. By understanding key aspects that make HTML5 development different from Flash you will be able to integrate your current skill set into the HTML5 development paradigm. Starting with identifying the key technologies that make up the HTML5 development stack and how they are utilized to create HTML5 content, HTML5 for Flash Developers will cover the traditional HTML5 application development flow chapter by chapter, while covering many other common tools that are regularly used in HTML5 today.In addition to understanding and writing dependency-free HTML5 code, you will also learn how to build your HTML5 applications on top of popular libraries and frameworks such as jQuery and CreateJS. This book covers how to prepare all of your content and media for integration into your HTML5 application using applications such as the Miro Video Converter or Adobe Photoshop. You will learn ways to not only continue to use Adobe Flash in your HTML5 application content preparation flow, but also how to port your existing Flash content right over to HTML5.Once you understand what it takes to build HTML5 content, you will finish up by learning how to debug, optimize, and prepare your content for release on the Web.

JavaScript events


As with most languages, events are what really brings an application to life. Without the use of events, programs would usually just run from start to finish without the need for human interaction. JavaScript events are built around the asynchronous event model. Rather than checking continually to see if a condition is met, events can use call-back structures, like in ActionScript, to execute code once an event has been fired. A great example of this, which you may have already seen in many other examples thus far:

window.addEventListener("load", init, false);

We use this Event Listener on the window object to allow our code to determine when the window object will finish loading, so that we can call our initial method to begin JavaScript manipulation of our document.

Keyboard and mouse events

Mouse events are another one of the core elements almost all JavaScript projects contain. Although we will be using these events within the examples all throughout this book, it's worth...
