enable submit button obly when all fields are filled

[Mathilde Pellerin]

Hi all,

I wonder if there is a simple way to enable the submit button of a form only
when all fields of this form are filled?
Thanks to AjaxFormComponentUpdatingBehavior, I can enable my button when I
fill a field, but I want enable my button only when all fields are filled
and I don't know how to do that.

Is there a method like AjaxFormComponentUpdatingBehavior but for entire
form?

thanks
