Validation and Submission of form using jQuery :: Easiest Solution

In any application, form validation and submission to server is so common and redundant; there are multiple ways of doing it. And the best and easiest way that I do use or recommend is jQuery solution.  Most popular jQuery plugins are the best solution, they have the best solution ever.  One, jQuery Validator written and maintained by Jorn Zaefferer, a member of the jQuery team, lead developer on the jQuery UI team and maintainer of QUnit. Two, jQuery Form by malsup, it has various plugins and solutions. Another plugin that I like from same developer is jQuery BlockUI . (give a try). Name: Email: Note: To avoid unexpected behavior, maintain same form and fields names and id selector values. Need further explanation, let me know.
