Validate-amd

Validate-amd library

validate.js is a small library to help form validation. This library uses amd structure.

It uses html5 form attributes validate specification and works on browsers that does not support html5 validation. Then, we built it from scratch.

Installation

npm install elo7-validate-amd

Dependencies

Validate-amd depends on an amd implementation. We suggest async-define implementation for dependency lookup. Validate-amd also depends on doc-amd.
