You can write your javascript like this:

    function Jvalidate() {

        var r = document.getElementById("yourRequiredFieldValidatorID");

        if (r.style.visibility == "hidden") {
            //Do your Stuff
            //Return the state accordingly.
        }
        else {
            return false;
        }
    }
