MVC / Jquery unobtrusive validation

http://www.devtrends.co.uk/blog/the-complete-guide-to-validation-in-asp.net-mvc-3-part-1

Also for how do attach a new client side method to unobtrusive validation e.g.

jQuery.validator.unobtrusive.adapters.add(adapterName, [params], fn);

see this article...

Note: For any element a in your <form>, you can do this to figure out what validation is attached to the containing <form> for that element...

$.data(a.form, "validator").settings.rules

e.g.

$.data(a.form, "validator").settings.rules.MiddleInitial
Object {maxlength: "1", __dummy__: true}

$.data(a.form, "validator").settings.messages.MiddleInitial
Object {maxlength: "The middle initial must be a single charater"}
