I just resealed version 9.0 of validate.js, lots of improvement. I expect future changes up to 1.0 to be mostly unit tests additions and bug fixes.

Sorry for the lack of documentation, I don't have a lot of free time. Contributors are welcome.

Changes log.

• added class attribute initialization (only support default callback function)
• enhanced default validation callback function, now support error message display before or after the input
• fixed form validation
• added default (demos) styles (see tests/index.html)
• added form validation tests
• added validation error messages (english)
• added isUnModified
• removed isValidEmpty, isValidNotEmpty, isValidRequired because of their ambiguity
• removed isRequired (use isNotEmpty instead)
• code cleanup, optimizations, added some comments
• Added unit tests
• Added prototype.js (needed for unit tests)
• Fixed isValidEmail validation problem with 2 characters domains
