Is there a AEX for Javascript functions?

[mvaughn]

I have some javascript functions that I want hidden from anyone inspecting an a5w page's source code.
Is it possible?

From Stackoverflow: It is not possible to hide Javascript from the user, since their browser needs to download it to execute it. The only other option is obfuscation.And the link they show is http://en.wikipedia.org/wiki/Obfuscated_code. There are online obfuscation tools.

Thanks Steve, but I think what I want is Server Side JavaScript (SSJS), if that's even possible?
Might be an interesting hack though.

I had not heard of SSJS. Reading online, it looks like SSJS would not do what we traditionally think of as client side actions. It would be like using .asp or php, or Alpha Five for that matter. I would think server-side IS server-side even if written using some variation of Javascript.

Steve's correct. SSJS was built by web programmers who wanted to write in Javascript for both client-side language and server-side language. The SSJS could be hidden because it's interpreted on the server by an application server built to read the SSJS (like XBasic is read on the WAS), but any client-side Javascript would still be accessible in the source as Steve noted in his first post.

I do wonder, depending on your situation, if it's something you'd be doing an Ajax Callback with. You could specify a javascript string as the Ajax callback function return and it at least wouldn't be sitting on the source page all the time (someone please correct me if I'm wrong--I probably am).

Re: Is there a AEX for Javascript functions?

I get to return Chris' acknowledgement and say that yes, the JS from a callback would be hidden. Like if you set an onClick function that ran a callback, that returned some js -- the first js (the onClick) will be visible, in the browser source, but the js returned from the callback will not be visible.

BUT it is only hidden in the web page source. Someone could still see it after it is executed in a product like Firebug.

Note - I wasn't totally sure about this, so I tested it. The part in red in my attachment is the JS returned from the callback.

Wakanda uses only JS, including Server Side JavaScript. But that won't help you here.

If it executes client-side, no. The best you can do is minify: http://javascript-minifier.com/

If you have an algorithm you absolutely do not want any user to see, read, view, examine, save, parse, steal, etc, do not use client-side javascript. Don't even let it leave the server. Write it in xbasic and send something else to the client.

Here's something interesting... http://nodejs.org/

Re: Is there a AEX for Javascript functions?

This is also server-side JS. Doesn't help you with the original need.

Your only hope to "hide" javascript is to "Obfuscate" the code using tools such as http://javascriptobfuscator.com/
