scroll-manager

A handler for scrolling inside elements with different eases

Take a look to the demo --> Demo

var ScrollManager = require('scroll-manager');
this.scroller = new ScrollManager();

var elementTo = document.getElementById('elementID');
var callback = function(){
  console.log("I'm done with scroll stuff");
};

var options = {
  duration: 0.8,
  to: elementTo.offsetTop
  element: document.body,
  ease: 'easeLinear'
};

this.scroller.scrollTo(options, callback);

##Examples

###ScrollToElement

//If you want to scroll to an element without using the offset you can use:
var element = document.getElementById('elementID');
this.scroller.scrollToElement({element: document.body, to: element, duration: 0.6, ease: 'easeOutExpo'});

###ScrollTo

//This scroll the element to the offsetToScroll in the required duration with the default ease
this.scroller.scrollTo({element: document.body, to: 100, duration: 0.6});

//This scroll the element to the offsetToScroll in the required duration with the selected ease and finally execute the callback
this.scroller.scrollTo({element: document.body, to: 100, duration: 0.6, ease: 'easeOutCubic'}, callback);

####Horizontal

//You also can use the method scrollTo to scroll horizontal in the element, you only need to set the direction  
this.scroller.scrollTo({direction:'horizontal', element: document.body, to: 100, duration: 0.6, ease: 'easeOutCubic'}, callback);

###ScrollTop

//This scroll the element to the top in the required duration with the selected ease and finally execute the callback
this.scroller.scrollTop({element: document.body, duration: 0.6, ease: 'easeOutCubic'}, callback);

###ScrollBottom

//This scroll the element to the bottom in the required duration with the default ease
this.scroller.scrollBottom({element: document.body, duration: 0.6});

###ScrollRight

//This scroll the element to the right of an element in the required duration with the selected ease and finally execute the callback
this.scroller.ScrollRight({element: document.body, duration: 0.6, ease: 'easeOutCubic'}, callback);

###ScrollLeft

//This scroll the element to the left of an element in the required duration with the default ease
this.scroller.ScrollLeft({element: document.body, duration: 0.6});

###ScrollEqual

//If you want to scroll with the same velocity without taking into acount the duration you can use:
this.scroller.scrollEqual({element: document.body, velocity: 100, to: 100, ease: 'easeOutCubic'});  
//This is useful if you want the user feel the difference between short and long distances.
