" Right, there are a lot of non-j Query-based solutions (which you'd avoid since you found j Query) and some j Query-based solutions.This particular one is one of the oldest j Query plugins (started in July 2006) and has proved itself in projects all around the world.The plugin is written and maintained by Jörn Zaefferer, a member of the j Query team, lead developer on the j Query UI team and maintainer of QUnit.It was started back in the early days of j Query in 2006, and updated and improved since then.This example requires that a Text Box and Error Provider control have been created on a form.This j Query plugin makes simple clientside form validation easy, whilst still offering plenty of customization options.
Of course that isn't the only way to specify rules.
The validator object has more methods, but only those documented here are intended for usage.
property The General Guidelines section provides detailed discussion of the design and ideas behind the plugin, explaining why certain things are as they are.
But I think it would be something like reinventing the wheel..much effort...
It's difficult to tell what is being asked here.
