        });
    });

initialize multiple similiar sliders


        'use strict';

        document.addEventListener('DOMContentLoaded', function () {
            Array.prototype.slice.call(document.querySelectorAll('.js_slider')).forEach(function (element, index) {
                lory(element, {});
            });
        });

Consume it as a commonJS module


    "use strict";

    var lory = require('lory.js').lory;

    document.addEventListener('DOMContentLoaded', function() {
        var slider = document.querySelector('.js_slider');

        lory(slider, {
            // options going here
        });
    });

Consume it as an ES2015 module


    import {lory} from 'lory.js';

    document.addEventListener('DOMContentLoaded', () => {
        const slider = document.querySelector('.js_slider');

        lory(slider, {
            // options going here
        });
    });

Use it as a jQuery Plugin


        <script src="js/jquery.lory.min.js"></script>


        'use strict';

        var $elements = $('.js_simple');

        $(function() {
            $elements.lory({
                infinite: 1
            });

            $elements.data().lory.slideTo(4);
            // $elements.data().lory.prev();
            // $elements.data().lory.next();
        });

Public API

prev: slides to the previous slide
next: slides to the next slide
slideTo: slides to the index given as an argument: (arguments: index {number})
returnIndex: returns the index of the current slide element
setup: binds eventlisteners, merging default and user options, setup the slides based on DOM (called once during initialisation) Call setup if DOM or user options have changed or eventlisteners needs to be rebinded.
reset: sets the slider back to the starting position and resets the current index (called on Resize event)
destroy: unmount/destroy the instance of lory

Options

slidesToScroll slides scrolled at once default: 1
enableMouseEvents enabled mouse events default: false
infinite like carousel, works with multiple slides. (do not combine with rewind) default: false (number of visible slides)
rewind if slider reached the last slide, with next click the slider goes back to the startindex. (do not combine with infinite) default: false
slideSpeed time in milliseconds for the animation of a valid slide attempt default: 300
rewindSpeed time in milliseconds for the animation of the rewind after the last slide default: 600
snapBackSpeed time for the snapBack of the slider if the slide attempt was not valid default: 200
ease cubic bezier easing functions: http://easings.net/de default: 'ease'
classNameFrame class name for slider frame default: 'js_frame'
classNameSlideContainer class name for slides container default: 'js_slides'
classNamePrevCtrl class name for slider previous control default: 'js_prev'
classNameNextCtrl class name for slider next control default: 'js_next'

Events

before.lory.init fires before initialisation (first in setup function)
after.lory.init fires after initialisation (end of setup function)
before.lory.slide arguments: currentSlide, nextSlide fires before slide change
after.lory.slide arguments: currentSlide fires after slide change
on.lory.resize fires on every resize event
on.lory.touchstart fires on every slider touchstart event
on.lory.touchmove fires on every slider touchmove event
on.lory.touchend fires on every slider touchend event
on.lory.destroy fires when the slider instance gets destroyed
