validate field based on regex in js

[bnomei]

i do not care so much about general validation ability but regex i would love to see. otherwise i could not use this plugin for complex pages.

you could use the parsley.js lib to validate in panel based on regex expressions.
i usually forward the blueprint regex to my frontend form with parsley. worked well so far.

nevermind. i missunderstood what costum validators where.
