Flash全屏功能详解

通过flash 9新功能来实现全屏技术要注意以下几点：
      a、flash player版本必须是 9.0.18.60或更高版本；
      b、调用全屏功能代码需通过触发事件才可以运行的，如onPress,onRelease事件；
      c、在插入html 代码时需设置<param name="allowFullScreen" value="true" />；
      d、经多次研究发现，如 html代码设置成<param name="wmode" value="opaque" />或<param name="wmode" value="transparent" />时，则全屏功能无效！也就是说只有flash窗口模块设置为window时，全屏功能才有效.
