不，没有什么可以阻止即使是中等智能的用户看到你的js源代码。微软可以选择加密js文件，但是（a）这意味着你的js只会在IE上运行，并且

（b）2分钟Google会为你找到一个解密js的实用工具。


你可以尝试使用javascript混淆器去除注释和空格

并用更短的替换有意义的变量名毫无意义的，但是

这样做的主要好处是它减少了下载时间，而且确实如果你需要调试任何东西，它会让你感到痛苦。

不是真的。

需要在用户计算机上执行js文件，因此代码以某种方式获得
。浏览器必须能够读取代码，如果浏览器可以使用
，那么用户也可以。

php与此无关，导致它在

服务器上运行，这是在其他地方。

No, there is nothing which you can do to stop even moderately intelligent
users from seeing your js source code. Microsoft have an option to
''encrypt'' js files but (a) this means your js will only ever run on IE, and
(b) 2 minutes with Google will find you a utility to unencrypt the js.

You can try using a javascript obfuscator to remove comments and whitespace
and replace meaningful variable names with shorter meaningless ones, but
the main benefit of this is that it reduces download times, and it does
make it more painful if you ever have to debug anything.

not really.
the js file needs to be executed on the users computer, so the code has
to get there somehow. the browser must be able to read the code, and if
the browser can, so can the user.
php has got nothing to do with that at all, cause it runs on the
server, which is somewhere else at all.

Ok and thanks, Duncan and Micha!!!
