HTML5 for Flash Developers

Chapter 2. Preparing for the Battle

Now that you understand what technologies make up HTML5, we can start getting our hands dirty. But before we jump right into coding HTML, CSS, and JavaScript, we need to cover the fundamentals of the first step of developing a project, asset preparation. Without a design, assets, and content, your web pages won't be very appealing or, for that matter, functional. During the preparation we will also dig into the syntax specification for JavaScript and how it's related to ActionScript 3, to prepare us for full-fledged development in Chapter 3, Scalability, Limitations, and Effects.

In this chapter we will cover:

The preparation of common assets such as images, audio, and video for use within an HTML5 document
In-browser code outputs and debugging
The basics of JavaScript and the syntax variance from ActionScript 3
Examples of JavaScript in action and the proper methods for code execution

Syntax differences

Now that we have some media to work with and the browser tools at our disposal, let's start some more toying with JavaScript and compare its syntax to what you already know in ActionScript 3.

Variables

Unlike variables declared within ActionScript 3, JavaScript variables are not strictly typed. This takes the familiar ActionScript 3 variable declaration from:

var myVariable:String = 'abc123';

to a simpler syntax within JavaScript which looks as follows:

var myVariable = 'abc123';

This lack of strict typing is referred to as dynamic typing. Variables in JavaScript can be used as any type at any time. Consider this example:

var exampleVar;                      // A undefined variable
exampleVar = "Some example text";    // Variable is now a String
exampleVar = 12345;                  // Variable is now a Number

Dynamic typing allows code to be writing faster by requiring less input from the developer, but this development ease comes at the cost of debugging large applications...

Description

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.

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.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

Great book to get started with HTML5. The chapters in the book are nicely organized and covers a few important concepts like websocket protocol.If you are really looking for intensive programming book in HTML5 then you may also need to refer to other books along with this. However if you are a novice developer like me you will find this book a great way to get started and very intuitive.

It's a good book for anyone interested to start learning HTML5 and even better for people with Flash Development experience.The fundamental concepts of HTML5, like JavaScript, CSS and HTML are explained in a simple and clear way with good examples.As a experienced HTML5 developer I enjoyed most the part of CSS media queries and transformations, I also like that the book is very practical and also suggests real world solutions: software and libs to help convert old flash software to html5 or develop in a Flash manner.
