Flash的debug是个头疼的问题，最好的方法是使用flash的logging来做日志调试。
要使用Flash的debug，首先要安装adobe的debug版flash，然后要配置mm.cfg，具体路径和配置方式见以下链接：http://livedocs.adobe.com/blazeds/1/blazeds_devguide/help.html?content=services_logging_2.html，之后就可以使用Flash的logging。
下面给个实例吧：
import mx.logging.*;
import mx.logging.targets.*;
private var myLogger : ILogger;
public function printLog(level:Number):void {
if(level ==2) myLogger.debug("This is debug click");
if(level == 4) myLogger.info("This is info click");
if(level == 6) myLogger.warn("This is warn click");
if(level == 8) myLogger.error("This is error click");
if(level ==1000) myLogger.fatal("This is fatal click");
}
private function initLog():void {
// Create a target.
var logTarget:TraceTarget = new TraceTarget();
logTarget.filters=["*"];
logTarget.level = LogEventLevel.ALL;
// Add date, time, category, and log level to the output.
logTarget.includeDate = true;
logTarget.includeTime = true;
logTarget.includeCategory = true;
logTarget.includeLevel = true;
// Begin logging.
Log.addTarget(logTarget);
myLogger = Log.getLogger("test");
}
点击之后的结果如下：
1/4/2009 20:04:41.149 [FATAL] test This is fatal click
1/4/2009 20:04:41.740 [ERROR] test This is error click
1/4/2009 20:04:42.695 [WARN] test This is warn click
1/4/2009 20:04:43.283 [INFO] test This is info click
1/4/2009 20:04:44.056 [DEBUG] test This is debug click
