VanadiumJS: A Powerful, Simple, and Intuitive Client-Side Validator

VanadiumJS is a free powerful easy customizable client-side validator that supports AJAX and regular server-side response results. This unobtrusive AJAX-enabled server-side technology agnostic JavaScript validation toolkit is very easy to install: you just have to include the vanadium js file after the dependency.

<head>
<script src="/js/jquery-latest.js" type="text/javascript"></script>
<script src="/js/vanadium.js" type="text/javascript"></script>
</head>

The validation rules are applied to the HTML form elements that have special markup classes (e.g. adding ‘:required’ to the elements’ classes).

Example 1
Password fields validation

<input id="pass" class=":required" type="password">
<input class=":same_as;pass" type="password">

Example 2
Delay the Vanadium reaction on user changes

<input class=":required :wait;500" type="text">
