AS3跨域加载SWF文件

Posted 2021-02-25

From the Big Spaceship Labs website.
This is a useful workaround for the following error message ...
SecurityError: Error #2142: Security sandbox violation: local SWF files cannot use the LoaderContext.securityDomain property.

var l:Loader = new Loader();
l.contentLoaderInfo.addEventListener(Event.COMPLETE, _onLoadComplete_handler);
if(Security.sandboxType == Security.REMOTE){
	var context:LoaderContext = new LoaderContext();
	context.securityDomain = SecurityDomain.currentDomain;
	l.load(new URLRequest('http://domain.com/extFile.swf'), context);
}else{
	l.load(new URLRequest('extFile.swf'));
