🦖 dino-validation

A vanilla JavaScript form validation library - no jQuery required.

⚠️ Work in Progress - This library is currently under active development and not yet ready for production use.

This library is a vanilla JavaScript port of these 2 libraries:

• jQuery Validation Plugin by Jörn Zaefferer
• jQuery Unobtrusive Validation by .NET Foundation

Builds

dv.umd.js - Core library with programmatic API (like jQuery Validation)

dv.validate('#myForm', { rules: { email: { required: true } } });

dv-auto.umd.js - Auto-parsing build with declarative HTML attributes (like jQuery Validation + Unobtrusive)

<input name="email" data-val="true" data-val-required="Email is required" />
<!-- Automatically validates on page load -->
