I have built an app that validates forms client side with html5. I'm looking for the javascript-implementation that best emulates this behavior in older browsers.

Important qualities are:

• As similar behavior as possible.
• As little modification of css/html as possible
• As little functionality besides field-validation built in as possible

Answer 1

CSS tricks has a nice article on the fallback process here: http://css-tricks.com/progressively-enhancing-html5-forms/

They also suggest a project such as this http://code.google.com/p/webforms2/

Which includes some of the HTML5 form validation goodness

Just remember to always check server side too when it comes to validation :)
