[jQuery] [validate plugin] contain number

[jQuery] [validate plugin] contain number


Hello,
I need to validate password fields. I got this list of requirements
what a password can be, among them: it has to contain numbers.
How can I validate if the password contains numbers or not.
I thought the built in numbers() method would do it for me. but it
seems it requires the string to be all numbers. I thought the digit()
would require all characters to be numbers and the numbers() would
check if the string has numbers.
Thanks for help,
Luke
