保留条件注释的缩小器？
我尝试了在线 JS Minifier 但它会删除条件注释，例如：
var u = navigator.userAgent;var e=/*@cc_on!@*/false;
BECOMES
var u=navigator.userAgent;var e=false;
这会影响操作因此，我正在寻找一个可以智能地保留这些和任何此类注释的缩小器，而不是手动添加删除的注释。
I tried out the online JS Minifier but it cuts out conditional comments like:
var u = navigator.userAgent;var e=/*@cc_on!@*/false;
BECOMES
var u=navigator.userAgent;var e=false;
This would affect the operation of the code, so instead of manually adding the stripped out comments manually, I'm looking for a minifier that intelligently preserves these and any such comments.

但不用担心，事情并没有你想象的那么糟糕。 不幸的是，JSMin 删除了条件编译注释，但我相信这是由于有一段时间没有更新，并且没有跟上现代 Web 开发实践的速度。
使用其他工具（例如 YUI 压缩器或打包器）确实可以很好地处理条件编译。

YUICompressor reportedly does the needful. Here is an excerpt from a blog:
...
But fret not, it’s not as bad as you think. Unfortunately, JSMin removes conditional compilation comments, but I believe this is due to not having been updated in a while, and not up to speed with modern web development practices.
Using other tools such as YUI compressor or packer does indeed work fine with conditional compilation.

还有 YUI Compressor 的 .NET 端口，它允许您：-
。 因为这是 Vinnie 和 Crescentfresh 上面提到的（原始）java 版本 YUI Compressor 的端口，它应该给您相同的结果，但全部在 .NET 环境中 - 不需要 java。
HTH。
There's also a .NET port of YUI Compressor which allows you to:-
because this is a port of the (original) java version YUI Compressor, which Vinnie and Crescentfresh mention above, it should give you the same results BUT all in the .NET environment -- no need for java.
HTH.
