Macromedia Fundamentals of ActionScript in Flash MX Seminar 英文光碟正式版
ActionScript是Flash 的腳本語言,與JavaScript相似，ActionScript是一種面向
對像編程語言。Flash使用ActionScript給動畫添加交互性。在簡單動畫中，Flash
按順序播放動畫中的場景和幀，而在交互動畫中，用戶可以使用鍵盤或鼠標與動畫
交互。例如，可以單擊動畫中的按鈕，然後跳轉到動畫的不同部分繼續播放；可以
移動動畫中的對象；可以在表單中輸入信息等等。使用ActionScript可以控制Flash
動畫中的對象，創建導航元素和交互元素，擴展Flash創作交互動畫和網絡應用的
能力。
ActionScript的新特點：
Flash 的ActionScript為創建包含複雜遊戲、表單、調查表和實時交互性的網站提
供了許多新的特性。現在就讓我們來看看Flash 5的ActionScript有哪些新的特點。
1.ActionScript與JavaScript之間的差異
ActionScript與JavaScript核心編程語言很相似，同樣具有函數、變量、語句、操
作符、條件和循環等基本的編程概念。不瞭解JavaScript也可以學習和使用Action
Script。
但是，如果瞭解JavaScript，你就會對ActionScript感到熟悉。ActionScript與
JavaScr pt之間主要有以下幾點不同：
ActionScript不支持瀏覽器特有的對象，如文檔、窗口和錨點。
ActionScript不完全支持所有JavaScript的預定義對象。
ActionScript支持JavaScript中不允許使用的語法結構（如tellTarget和ifFrame
Loaded 動作和slash語法）。
ActionScript不支持某些JavaScript語法結構（ switch、continue、try、catch、
throw和labels語句）。
ActionScript不支持JavaScript的函數結構體。
在ActionScript中，eval動作僅執行變量的引用。
ActionScript不支持Unicode編碼，它支持ISO-8859-1和Shift-JIS字符集。
Macromedia Flash MX offers the best solution for developing rich content
and Internet applications that deliver the best user experiences with
significant return on investment.
Macromedia Flash MX ActionScript is an object-oriented scripting language
based upon ECMAScript. ActionScript is the feature within Macromedia Flash
MX which allows the designer to control the movie playhead in a non-linear
fashion, create sophisticated interactivity, control elements on the Stage,
collect and track input from the movie viewer, as well as exchange and
manipulate data from external sources.
Through June 25, 2002, one lucky participant will win a full version of
Macromedia Flash MX.
What You Will Learn:
During the course of the seminar, we will move through the concepts of
ActionScript. We'll start with a description of ActionScript in plain
English, and then work through the terminology that will become the
building blocks for our ActionScript projects.
With our new vocabulary firmly in hand, we'll then walk through a number
of basic tutorials that illustrate the practical application of
ActionScript concepts. The tutorials will progress from the basics--
designed for everyone to work from the same starting point—to more
advanced techniques that will benefit even the most skilled Macromedia
Flash developers.
All attendees will receive a CD-ROM containing the entire content of the
seminar—step-by-step QuickTime movies, source files, and examples, along
with a number of other sample files.
Topics covered during the session include:
ActionScript Basics
· Understanding ActionScript syntax
· Controlling the timeline with ActionScript
· Leveraging movie clips and buttons
· Retrieving and manipulating properties
ActionScript Techniques
· Events and triggers
· Building and using functions
· Using simple and multidimensional arrays
· Using external data sources to dynamically add content to your Macromedia Flash MX movie
· Troubleshooting and debugging your Macromedia Flash MX movie
