Какой смысл в throw?

где без this вообще никак?

function Arr() {
  this.name = "Stive",
  this.age = 29,
  this.all = function() {
    return this.name + " " + this.age;
  }
};

var arr = new Arr();
console.log(arr.all());

.owl-prev.disabled, .owl-next.disabled {
  display: none;
}

var fname=url.replace(/.+\//,"");
fname = 'd:\\path\\to\\file\\' + fname;

$('a').on('click', function(){
  var target = $(this).data('target');
  var pos = $(target).offset().top;
  $('html, body').animate({'scrollTop': pos - 100}, 400);
});

просто в пикселях высчитывать расстояние скролла - идея плохая,
