As far as I experienced, no.
You could only sign certain form fields as "required".
So the submit button "works" only, if those fields are filled.
There might be a design solution, if you place the "submit" further down, create an additional button to ask, wether everyrthing is filled out properly, right below the form, link this to the anchor, where you have placed your submit button. But, you could also "shoot yourself in the foot", if you know what I mean.
Many thanks for your reply, as you say I may be shooting myself in the foot, but it's an interesting solution to the problem.
