ParselyJS Custom Validator for Passwords

parsely-password.js

window.ParsleyValidator.addValidator 'password', (value, requirements) ->
  requirements = requirements.split ','
  regexPatterns =
    upperCase: '[A-Z]'
    lowerCase: '[a-z]'
    number: '[0-9]'
    symbol: '[@#$%^&!*()_+<>]'
  isValid = true
  for key in requirements
    if isValid && regexPatterns[key]?
      isValid = false unless value.search(regexPatterns[key]) >= 0
  return isValid
.addMessage 'en', 'password', 'This password does not meet the requirements.'

Add this to your forms constructor and pass in a comma-delimited set of strings like

<input data-parsley-password="upperCase,number,symbol"/>
