有很多的使用痕迹（）来打印结果的例子为ActionScript在Web上。

我tryied它使用Flash Builder 4，但是不打印到控制台。我在哪里可以看到输出？

解决方案 您在调试模式？ 把一个断点，其中跟踪（）被写的行（按Ctrl + Shift + B），调试，看看痕迹为止。 您是否打印正确的字符串？尝试做跟踪时，如跟踪（加载文件，_myFile.url）也使用一个静态文本在前面;

There's a lot of examples for ActionScript over the web using trace() to print results.

I'd tryied it using Flash Builder 4, but it don't print to the console. Where can I see the output?

解决方案

Are you in debug mode ? Put a breakpoint on the line where the trace() is wrote (ctrl+shift+b), debug and see if the trace is reached. Are you printing the right string? try to use also a static text in front when doing trace like trace("Loading file: ", _myFile.url);
