make enterViewport cancellable #20

Open rstacruz opened 9 years ago

rstacruz commented 9 years ago

it'd be nice to make it cancellable:

$('#header').scrollupbar({
  enterViewport: function () {
    // prevent entering if the page is still too high.
    if ($(window).scrollTop() < 1000) return false
  }
})
