AS3：获取帧标签帧号的简单方法

 private function getFrameByLabel( frameLabel: String ):int
 {
       var scene:Scene = yourMovieClip.currentScene;

       var frameNumber:int = -1;

       for( var i:int ; i < scene.labels.length ; ++i )
       {
            if( scene.labels[i].name == frameLabel )
                frameNumber = scene.labels[i].frame;
       }

       return frameNumber;
  }

import flash.display.FrameLabel;

var frameNumber:int = -1;
frameNumber = MyMovieClip.currentFrame;
