Question

How can I protect my implemented JS methods from user? So that no one could copy these methods. Normally, User can see JS methods in firebug easily. I want to hide methods in firebug also.
Is there any trick to hide methods from users?

Note: I don’t want to use Eval method. so please don’t suggest me to eval based tricks

Answer 1

1. try packing the code/minifiying it

google closure compiler is a good start

there is also a YUI lib that you can use and many others.

This will make your code pretty much impossible to debug in firebug.

There is no full proof way though to stop users for mucking with your code, since it does run on the client side by definition.

1. Another thing you can do is put the methods you want to hide inside of a closure, so that the user cant simply run someMethod() from firebug and have it execute code.
