jQuery.UI.Combined by: jQuery UI Team

jQuery UI is an open source library of interface components — interactions, full-featured widgets, and animation effects — based on the stellar jQuery javascript library . Each component is built according to jQuery's event-driven architecture (find something, manipulate it) and is themeable, making it easy for developers of any skill level to integrate and extend into their own code.

jQuery.Validation by: Jörn Zaefferer

This jQuery plugin makes simple clientside form validation trivial, while offering lots of option for customization. That makes a good choice if you’re building something new from scratch, but also when you’re trying to integrate it into an existing application with lots of existing markup. The plugin comes bundled with a useful set of validation methods, including URL and email validation, while providing an API to write your own methods. All bundled methods come with default error messages in english and translations into 32 languages.
