  easing: 'linear',
  animation: 'fade', // fade, slide, none
  animationSpeed: 500,

  mobile: {
    width: 768,
    distance: 100,
    speed: 1000,
    easing: 'easeInOutElastic',
    animation: 'slide',
    animationSpeed: 200
  },

  trigger: null, // Set a custom triggering element. Can be an HTML string or jQuery object
  target: null, // Set a custom target element for scrolling to. Can be element or number
  text: 'Scroll To Top', // Text for element, can contain HTML

  skin: null,
  throttle: 250,

  namespace: 'scrollToTop'
}

Methods

Methods are called on scrollToTop instances through the scrollToTop method itself. You can also save the instances to variable for further use.

// call directly
$().scrollToTop('destroy');

// or
var api = $().data('scrollToTop');
api.destroy();

jump()

Jump to top.

$().scrollToTop('jump');

destroy()

Events

  // on jump to top
});

<script src="other-plugin.js"></script>
<script src="jquery-scrollToTop.js"></script>
<script>
  $.scrollToTop.noConflict();
  // Code that uses other plugin's "$().scrollToTop" can follow here.
</script>
