package {
    import flash.system.Capabilities;
    import flash.display.MovieClip;

    public class VersionCheck extends MovieClip{
        public function VersionCheck():void {
            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.");
            }
        }
    }
}

如果跟踪语句说：

您的 Flash Player 版本低于当前版本 9，请更新。

如何使用 Actionscript 启动 Flash Player 的自动更新？

【问题讨论】：

标签： actionscript flash

【解决方案1】：

你不能那样做。也会真的很烦。大量网站会开始更新我的 Flash 播放器，尽管我只想坚持使用现有的（无论出于何种原因）。

另外，请注意代码是 AS3，并且 AS3 无法编译为在低于版本 9 的 Flash 播放器上运行。因此，您的脚本要么运行检测播放器版本足够，要么根本不运行。

adobe 和其他人为 Flash 嵌入提供了 HTML 模板，并带有集成的 javascript 版本检查，如果您的版本不够新，它将为您提供一个手动升级 Flash 播放器的按钮。

    import flash.system.Capabilities;

// Get the player’s version by using the flash.system.Capabilities class.
var versionNumber:String = Capabilities.version;
trace("versionNumber: "+versionNumber);

// The version number is a list of items divided by ",”
var versionArray:Array = versionNumber.split(",");
var length:Number = versionArray.length;

// 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(" ");

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);

if (majorVersion<12) {
    trace("Your Flash Player version is older than the current version 9, please update.");
    //statusText is a label positioning at the left bottom corner of Stage
    statusText.htmlText = "<b>Your Flash Player version is older than the current version 12</b><a href='get.adobe.com/flashplayer/'>please update";
} else {
    statusText.text = "You are using Flash Player 12 or later.";
}
