ActionScript 3.0 Cookbook: Solutions for Flash Platform and Flex Application Developers (Paperback)
內容描述
Description
Well before Ajax and Microsoft's Windows Presentation Foundation hit the
scene, Macromedia offered the first method for building web pages with the
responsiveness and functionality of desktop programs with its Flash-based
"Rich Internet Applications". Now, new owner Adobe is taking Flash and its
powerful capabilities beyond the Web and making it a full-fledged development
environment.
Rather than focus on theory, the ActionScript 3.0 Cookbook concentrates on
the practical application of ActionScript, with more than 300 solutions you
can use to solve a wide range of common coding dilemmas. You'll find recipes
that show you how to:
Detect the user's Flash Player version or their operating system
Build custom classes
Format dates and currency types
Work with strings
Build user interface components
Work with audio and video
Make remote procedure calls using Flash Remoting and web services
Load, send, and search XML data
And much, much more ...
Each code recipe presents the Problem, Solution, and Discussion of how you
can use it in other ways or personalize it for your own needs, and why it
works. You can quickly locate the recipe that most closely matches your
situation and get the solution without reading the whole book to understand
the underlying code. Solutions progress from short recipes for small problems
to more complex scripts for thornier riddles, and the discussions offer a
deeper analysis for resolving similar issues in the future, along with
possible design choices and ramifications. You'll even learn how to link
modular ActionScript pieces together to create rock-solid solutions for Flex 2
and Flash applications.
When you're not sure how ActionScript 3.0 works or how to approach a
specific programming dilemma, you can simply pick up the book, flip to the
relevant recipe(s), and quickly find the solution you're looking
for.
