How to use FUI's API along with form that include a submit div

[JobberRT]

Official Example

I would like to bind FUI's API to the Login Button/Div, using jquery. Here's my code:JSFiddler

Question is, the very first click of a newly opened page, the form will do the validation, but the second click, will ignore whether the form is validated, and just send the request. Does FUI's API won't co-operate will FUI's class submit and automaticlly detect form validation?

What should i do to achieve FUI's API will do the request only when there is no error or the error was solved?
If FUI's API won't listen to form's validation, should i write a js function that check the validdation before FUI's API ? Is there a example?

Thank you guys!

got the answer from Here

It seeems that i just need $("#exampleForm").form().api(), which specify validation rules in .form() and do the request in .api()
