推荐答案

简短回答：你不能/不能。

更长的回答：你根本无法隐藏它。它在客户端上运行，无法编译为机器代码。
然而，你可以缩小它 - 这基本上是通过缩短变量名，删除空格等来混淆它。虽然它通常用于节省带宽，但它也使代码的可读性降低。
请注意，除了更改的变量名称和删除的注释之外的所有内容都可以通过像jsbeautufier这样的东西轻松撤消..但对于大型应用程序，很难理解没有任何有意义的变量/函数名称或注释的代码。

Longer answer: You cannot hide it at all. It runs on the client and it cannot be compiled to machine code. However, you could minify it - that's basically obfuscating it by shortening variable names, removing whitespace, etc. While it's usually used to save bandwidth it also makes the code less readable. Note that all but the changed variable names and removed comments can be easily undone by something like jsbeautufier.. but for a large application it's very hard to understand the code without any meaningful variable/function names or comments.
