Simple way to show trace statements in Flash and in the browser. Put in root. Go: console.log("Hello World!");

console.as

package
{
	import flash.external.ExternalInterface;
	
	public class console
	{
		public function console()
		{
		}
		
		private static function printToBrowserConsole(method:String, message:String):void
		{
			try
			{
				ExternalInterface.call(method, message);
			} 
			catch(error:Error) 
			{
				trace("console::printToBrowserConsole, error: " + error);
			}
		}
		
		public static function log(o:*):void
		{
			printToBrowserConsole("console.log", String(o));
		}
		
		public static function debug(o:*):void
		{
			printToBrowserConsole("console.debug", String(o));
		}
		
		public static function info(o:*):void
		{
			printToBrowserConsole("console.info", String(o));
		}
		
		public static function warn(o:*):void
		{
			printToBrowserConsole("console.warn", String(o));
		}
		
		public static function error(o:*):void
		{
			printToBrowserConsole("console.error", String(o));
		}
		
		// [jwarden 4.26.2012] NOTE: fatal is routed to error.
		public static function fatal(o:*):void
		{
			printToBrowserConsole("console.error", String(o));
		}
	}
