Ok finally I've found out that using onkeyup: false, onfocusout: false, onclick: false
the validation only works on the submit.... the unhappy thing is that the alert does not change in real time now as the value are putted in the inputs. I must have missed something... it is not normal that the form is being submitted on the validation process ! If anyone could help me out with this, I'd be so greatfull ! Antoine
