I suppose you already know you can't hide javascript.
You could sort of scramble it, though that still won't prevent it from being read by anybody: http://www.quadhead.de/jss.html

But I wonder, why do you even want to hide it?
Is your code really so special? Most likely, what you got is specific for what you want to do, so hardly of use to anybody else.
Second, there are millions of javascripts out there on the net for free download, whatever nifty little javascript effect you see, there's a free script for it somewhere...

I need a way to protect the product that I made

the product is a complete tool easily integratable in any website
equals javascript, client-side only, cookies, IE + NS compatible only

why to protect:
I want to prevent (discourage) implementors from altering the prog .js files
only data .js files should be readable

equals decrease product support and increase product life cycle


I agree that there are thousands of script on the net but I'm still looking for a complete tool-example.
JavaScript is client-side and perfect for form-tools.
Since its only client-side it increases the market -- no specific hosting requirements.

anyway thanks for the link --- I will give it a look.

100% protection doesn't exists, I know --- if I have 50% I'm more than satisfied.

Thx

www.dynamicdrive.com also has a code scrambler. You could use the one posted above, then scramble that output with the one a dynamic drive. It makes the js a little slower, but unless your really keen on getting the dirt on a script, it will serve its purpose.
