Tried to debug unfinishe's version, found a strange 4-bit shift which I was unable to fix:
1RRi5kDMck5cj2ob4UcjKxnGL2sjknRtv <- base58 address than gives false negative
00 04 9e 9b c9 36 6d fc 95 15 5e 53 00 84 a7 2a bf 6d 59 1f 07 <- b58decode
00 49 e9 bc 93 66 df c9 51 55 e5 30 08 4a 72 ab f6 d5 91 f0 72 <- javascript
It's either bignum or base58 implementation.
This one works fine http://pastebin.com/B5r3P5Ny (I used modified bitaddress.org code).
Topic: javascript address validation? 0.2 BTC bounty (bounty paid) (Read 4786 times)
I appear to have found a false negative.
This address does not pass, however is a valid bitcoin address:
1RRi5kDMck5cj2ob4UcjKxnGL2sjknRtv
Thoughts on what it doesn't like?

I figure it is out there somewhere and google is failing me, so only a small tip, 0.1 BTC, for an answer.
I will double that, purely out of curiosity... 0.1 from me too.
I am looking for something off the shelf that takes an address and validates it via javascript.
Something like this...
validate_btc( address )
{
return { version:0, hash:'...' } or false;
}
