check form

Hi

In this code the field must have at least 3 characters : (var minLength =
3;)
Code:
// check for Voornaam
if (document.Registreren.Voornaam.value.length < minLength) {
alert('You have to fill in at least 3 characters');
return false;
}

I want to chance the code, so that they have to fill in something, it may
not stay empty.

Regards,
Yammaski.

Not empty is the same as at least 1 char!

var minLength = 1;

function voornaamNietLeeg(x){
if (x.Voornaam.value.length < minLength) {
alert('You have to fill in at least '+minLength+' character[s]');
return false;
}
return true;
}

...............

<form onsubmit='return voornaamNietLeeg(this)'>
<input name='Voornaam'>
