ActionScript ActionScript is the fourth edition follows the ECMAscript Adobe Flash Player runtime programming language. It is in the Flash content and applications interact, data processing and other functions. ActionScript is the Flash scripting language, and similar to JavaScript, ActionScript is a programming language, use of the new out of AS3.0 OOP (object-oriented programming), increased ability to more error, the specified type is also more clearly defined.

actionscript explanation of related terms in the version history on the merits ActionScript3 Introduction to ActionScript 3.0 ActionScript 3.0, actionscript in the new features related terms 1.Actions (action): is the program statement,
air force 1 high, It is the actionscript scripting language of the soul and the core. 2.Events (event): short,
nike air force 1 high, to perform a certain action, certain conditions must be provided,
nike air force 1, such as the need for a particular event as a trigger for the action, then this is the actionscript part of triggering the events. 3.Class (class): is a series of links between each set of data used to define a new object type. 4.Constructor (constructor): used to define class properties and methods of the function. 5.Expressions (expression): to produce a statement in any part of the value. 6.Function. (Function): refers to the parameters that can be transmitted and can return values as well as reusable blocks of code. 7.Identifiers (identifier): used to identify a variable, property, object, function or method name. 8.Instances (instance): instance is of a certain class of objects, each instance of a class contains all the properties and methods class. 9.Variable (variable): variable is the value of storing any data type identifier. 10. Instancenames (instance name): is the point in the script only movie clip instance name. 11.Methods (method): refers to an object to be assigned to a particular function, a function is assigned, it can be used as the object The method is called. 12.Objects (object): is a collection of attributes. Each object has its own name and the value of the object can be freely accessed by a particular type of information. 13.Property (characteristics): the object's unique property. Flash animation using ActionScript to add interactivity. In a simple animation, Flash animation sequence in the scene and frame, and in the interactive animation, the user can use the keyboard or mouse interaction with the animation. For example, you can click the button animation and then jump to different parts of the animation to play; can move objects in the animation; can enter information in the form and so on. Flash animation using ActionScript to control the object, the navigation elements and interactive elements to create, expand interactive Flash animation and web application creation capability. * ActionScript is explained in the Flash Player ActionScript Virtual Machine (AVM) to perform. * ActionScript code is usually compiled into * ActionScript is the primary IDE Adobe's Flash (the latest version of CS4 10.0 2008 年 10 月 sale) and Flex (the latest version of flex5.0). * Actionscript flash dynamic control is given a programming language within the mc, the instance name is a stage on the MovieClip, ActionScript can be controlled by using the stage name of the MovieClip instance of a component. Version History ActionScript 1.0 (Flash 1.0-6.0) corresponding to the virtual machine is AVM1, based on ECMA-262 V2 (equivalent to JavaScript 1.3) ActionScript 2.0 (Flash 7.0-8.0) corresponding to the virtual machine is AVM1, based on ECMA-262 V3 (rather in JavaScript 1.5) ActionScript 3.0 (Flash 9.0-?) corresponds to the virtual machine is AVM2, based on ECMA-262 V4 (equivalent to JavaScript 2.0) on the Introduction to ActionScript ActionScript3 is for Adobe Flash Player runtime programming language, it is Flash content and implement interactive applications, data processing and many other features. ActionScript is the Flash Player ActionScript Virtual Machine (AVM) to perform. ActionScript code is usually compiled by the compiler as compiler or Adobe ® Flex? SDK and Flex? Data Services provided by the compiler. Byte code embedded in the SWF file,
nike air force one high, SWF file from the Flash Player runtime environment implementation. ActionScript 3.0 programming model provides a reliable,
air force one low, have basic knowledge of object-oriented programming model for developers who will feel familiar to this. ActionScript 3.0, some of the key features include: a new ActionScript Virtual Machine, called AVM2, it uses a new bytecode instruction set, can significantly improve the performance of a more modern compiler code base, it is more strictly follow the ECMAScript (ECMA 262) standard, and compared to earlier versions of the compiler, perform more in-depth optimization of an extended and improved application programming interface (API), a low-level control of objects and the real face the object model to be released based on ECMAScript (ECMA-262) version 4 draft language specification of a core language based on ECMAScript for XML (E4X) specification (ECMA-357 2) of the XML API. E4X is ECMAScript,
air force one shoes, a language extension, it will add to the language of the XML native data type. A document object model based (DOM) Level 3 Events specification of the advantages of event model ActionScript 3.0 ActionScript 3.0 scripting capabilities beyond the earlier versions of ActionScript. It is designed to facilitate large data sets and create a reusable object-oriented code base of highly complex applications. Although ActionScript 3.0 in Adobe Flash Player 9 to run the content is not required, but it uses the new virtual machine AVM2 achieve performance improvement. ActionScript 3.0 code execution speed can be faster than the old ActionScript code 10 times. Old versions of the ActionScript Virtual Machine implementation AVM1 ActionScript 1.0 and ActionScript 2.0 code. For backward compatibility with existing content and old content, Flash Player 9 support AVM1. ActionScript 3.0, ActionScript 3.0 includes new features, while ActionScript programmers are familiar with many classes and functions, but in the framework and ActionScript 3.0 is different from the early concept version of ActionScript. ActionScript 3.0 Improvements in the core section includes new language features, and the ability to better control low-level objects to improve Flash Player API.
