本文详细介绍了在使用Flex进行项目开发时遇到全屏模式报错的问题，并提供了修改html-template文件夹下的xxx.template.html文件来解决该问题的方法。同时，文章还分享了一个简单的Flex全屏实现方法，包括如何监听并切换全屏状态。
在公司用Flex做项目的时候，发现全屏报 “SecurityError:Error #2152:不允许使用全屏模式” 的错误。后面经过研究是需要在修改FLex项目下html-template文件夹下的xxx.template.html文件：

增加红色的地方即可。注意需要重新编译Flex项目。
全屏的方法是：
protected function fullScreen(event:MouseEvent):void
{
try{
if (stage.displayState == StageDisplayState.FULL_SCREEN){
stage.displayState = StageDisplayState.NORMAL;
}else{
stage.displayState = StageDisplayState.FULL_SCREEN;
}
//此方法可以监听Esc退出全屏事件
stage.addEventListener(FullScreenEvent.FULL_SCREEN, handleFullScreenChange);
}catch(e:*){
CountDownAlert.show(e, "全屏时发生错误！");
}
}
handleFullScreenChange 方法为：
private function handleFullScreenChange(e:FullScreenEvent):void{
if(e.fullScreen){// 全屏即运行if代码段
fullScreenButton.label = "退出全屏";
fullScreenButton.toolTip = "退出全屏";
}else{ // 退出全屏则运行else代码段
fullScreenButton.label = null;
fullScreenButton.toolTip = "全屏模式";
}
fullScreenButton.emphasized = e.fullScreen;
}
Flex全屏现在就了解这么多，还有待深入了解。
