如何从动作脚本3.0了解Flash Player版本

有一种方法可以知道安装在使用Action Script 3.0运行我们的SWF文件的计算机上的flash player版本？

它在中如果您是从IDE中编程的，下面将获得该版本

trace(Capabilities.version); 跟踪（Capabilities.version）； 如果您正在构建一个自定义类，以下内容应该会有所帮助。 确保以下代码进入名为VersionCheck.as的文件

包裹 { 导入flash.system.Capabilities； 公共类版本检查 { 公共函数VersionCheck（）：void { 跟踪（Capabilities.version）； } } }

希望这有帮助，请记住，所有AS3语言都可以在这里在线学习。

这个例子可能有助于了解您收到的详细信息，以便您可以根据您获得的有点尴尬的数据中的细节采取行动

import flash.system.Capabilities;


var versionNumber:String = Capabilities.version;
trace("versionNumber: "+versionNumber);
trace("-----");

// The version number is a list of items divided by ","
var versionArray:Array = versionNumber.split(",");
var length:Number = versionArray.length;
for(var i:Number = 0; i < length; i++) trace("versionArray["+i+"]: "+versionArray[i]);
trace("-----");

// The main version contains the OS type too so we split it in two
// and we'll have the OS type and the major version number separately.
var platformAndVersion:Array = versionArray[0].split(" ");
for(var j:Number = 0; j < 2; j++) trace("platformAndVersion["+j+"]: "+platformAndVersion[j]);
trace("-----");

var majorVersion:Number = parseInt(platformAndVersion[1]);
var minorVersion:Number = parseInt(versionArray[1]);
var buildNumber:Number = parseInt(versionArray[2]);

trace("Platform: "+platformAndVersion[0]);
trace("Major version: "+majorVersion);
trace("Minor version: "+minorVersion);
trace("Build number: "+buildNumber);
trace("-----");

if (majorVersion < 9) trace("Your Flash Player version is older than the current version 9, please update.");
else trace("You are using Flash Player 9 or later.");

导入flash.system.Capabilities；
var versionNumber:String=Capabilities.version；
跟踪（“版本号：”+versionNumber）；
痕迹（“----”；
//版本号是项目列表除以“，”
var versionArray:Array=versionNumber.split（“，”）；
变量长度：Number=versionArray.length；
对于（变量i:Number=0；i

谢谢您的解释。没有必要，但很有帮助

import flash.system.Capabilities;


var versionNumber:String = Capabilities.version;
trace("versionNumber: "+versionNumber);
trace("-----");

// The version number is a list of items divided by ","
var versionArray:Array = versionNumber.split(",");
var length:Number = versionArray.length;
for(var i:Number = 0; i < length; i++) trace("versionArray["+i+"]: "+versionArray[i]);
trace("-----");

// The main version contains the OS type too so we split it in two
// and we'll have the OS type and the major version number separately.
var platformAndVersion:Array = versionArray[0].split(" ");
for(var j:Number = 0; j < 2; j++) trace("platformAndVersion["+j+"]: "+platformAndVersion[j]);
trace("-----");

var majorVersion:Number = parseInt(platformAndVersion[1]);
var minorVersion:Number = parseInt(versionArray[1]);
var buildNumber:Number = parseInt(versionArray[2]);

trace("Platform: "+platformAndVersion[0]);
trace("Major version: "+majorVersion);
trace("Minor version: "+minorVersion);
trace("Build number: "+buildNumber);
trace("-----");

if (majorVersion < 9) trace("Your Flash Player version is older than the current version 9, please update.");
