Answer 1

18 year old validation rule for jQuery Validator plugin using addMethod function.

jQuery.validator.addMethod(
        "validDOB",
        function(value, element) {              
            var from = value.split(" "); // DD MM YYYY
            // var from = value.split("/"); // DD/MM/YYYY

            var day = from[0];
            var month = from[1];
            var year = from[2];
            var age = 18;

            var mydate = new Date();
            mydate.setFullYear(year, month-1, day);

            var currdate = new Date();
            var setDate = new Date();

            setDate.setFullYear(mydate.getFullYear() + age, month-1, day);

            if ((currdate - setDate) > 0){
                return true;
            }else{
                return false;
            }
        },
        "Sorry, you must be 18 years of age to apply"
    );

and

$('#myForm')
        .validate({
            rules : {
                myDOB : {
                    validDOB : true
                }
            }
        });
