Answer 1

Return the value of the field using a function.

$( "#myform" ).validate({
    rules: {
        field: {
            required: true,
            max: function() {
                return parseInt($('#field1').val());
            }
        }
    }
});

Remember to enclose the value within parseInt or the number could be evaluated as a string.
