是否可以写code中，将只在调试版本上运行，或通过调试运行时，Flex应用程序？ 有没有的Flex提供了一种真正删除code完全由发布版本，如C风格的#define？

该应用程序不一定在网页中运行。

您可以做条件编译这样的：

  CONFIG ::调试{
    //如果CONFIG ::调试解析错误在编译时，这将被删除
}
 

然后把它添加到编译器标志：

  -define + = CONFIG ::调试，真
 

有关调试版本，以及

  -define + = CONFIG ::调试，假
 

有关发布版本。 配置和调试可以是任何东西，如 MY_AWESOME_NAMESPACE 和 foobar的，也没关系。

Is it possible to write code in a Flex application that will only be run in a debug build, or when running through the debugger? Does Flex provide a way to actually remove code entirely from release builds, like C-style #defines?

The app is not necessarily running in a web page.

You can do conditional compilation like this:

CONFIG::debugging {
    // this will be removed if CONFIG::debugging resolves to false at compile time
}

And then add this to the compiler flags:

-define+=CONFIG::debugging,true

for debug builds, and

-define+=CONFIG::debugging,false

for release builds. CONFIG and debugging can be anything, like MY_AWESOME_NAMESPACE and fooBar, it doesn't matter.
