That's javascript mixed with some php. In your example code everything
between the <? ?> tags is php, anything outside them is javascript. In this
case fieldRequired.length is a javascript command. To be precide, it refers
to a string object 'fieldRequired' and it's class member 'length'.
Ask in a javascript group.
