Vanadium is JavaScript validation toolkit that makes client-side validation easy. Validation rules can be applied to HTML elements by adding special markup classes or you can use external definition as JSON structure.
By default Vanadium will immediately validate an element when its value has changed, but you can also customize it to validate only on submit or wait certain amount of time before validating on element.
Developed by Daniel Kwiecinski; Vanadium is powered by jQuery and has been tested to work in: Firefox 3.5 (PC/Mac), Safari 2 (Mac), IE 6+, Opera 9 (PC/Mac). You can find further information, demo & download on Vanadium’s Website.
