Function return value in constructor

In Javascript functions can be arguments of a constructor but I would like to assign a conditional value to be evaluated when a new object is created.

var obj = {
  prop: function(){ return 1; },
  prop2: "asd"
};

console.log(obj.prop);  // This prints "function() ..."

With this method, Is there any way to make prop value 1 ?

For those of you wondering why I want to do this, I have the following code and I need to pass a different offset parameter if some condition is true or not.

$('#primary-menu > ul > li > a[href*=#]').smoothScroll(


{ preventDefault: true, easing: 'swing', speed: 700, offset: -200, exclude: ['.external a'],
    beforeScroll: function () {

        // Disable all waypoints on internal divs which are linked to from the menu
        $('#primary-menu > ul > li > a[href*=#]').each(function () {
            var element_id = MO_THEME.get_internal_link($(this).attr('href')); // Gives me ids of div's with ids like #work,#service, #portfolio etc.
            $(element_id).waypoint('disable');
        });
    },
    afterScroll: function () {
        // Enable all waypoints on internal divs which are linked to from the menu
        $('#primary-menu > ul > li > a[href*=#]').each(function () {
            var element_id = MO_THEME.get_internal_link($(this).attr('href')); // Gives me ids of div's with ids like #work,#service, #portfolio etc.
            $(element_id).waypoint('enable');
        });
    }});

You can change any of the options of the smoothScroll plugin after instantiation:

Setting options after initial call

If you need to change any of the options after you've already called .smoothScroll(), you can do so by passing the "options" string as the first argument and an options object as the second.

$el.smoothScroll('options', {
  offset: newValue
});
