GitHub - ganlanyuan/tiny-slider: Vanilla javascript slider for all purposes.

Tiny slider for all purposes, inspired by Owl Carousel ^[1].

Previous versions: v1, v0

Warning: tiny-slider works with static content and it works in the browser only. If the HTML is loaded dynamically, make sure to call tns() after its loading.

What's new

Using % instead of px (No more recalculation of each slide width on window resize)
Using CSS Mediaqueries if supported
Save browser capability values to localStorage ^[4], so they will not be recheck again until browser get upgraded or user clear the localStorage manually.
More options available for responsive. (Start from v2.1.0 ^[5], issue 53 ^[6])
Insert controls and nav before slider instead of after (issue 4 ^[7])
Move autoplay button out of nav container. (Start from v2.1.0 ^[8])
Some selector changes in tiny-slider.scss^[9]

Migrating to v2

Update controls and / or nav styles based on their position changes.
Update the slider selectors^[10] accordingly if used in your CSS or JS.
Update styles related to autoplay button.

Responsive options

The following options can be redefined in responsive field: startIndex, items, slideBy, speed, autoHeight, fixedWidth, edgePadding, gutter, center, controls, controlsText, nav, autoplay, autoplayHoverPause, autoplayResetOnVisibility, autoplayText, autoplayTimeout, touch, mouseDrag, arrowKeys, disable

<script>   var slider = tns({     container: '.my-slider',     items: 1,     responsive: {       640: {         edgePadding: 20,         gutter: 20,         items: 2       },       700: {         gutter: 30       },       900: {         items: 3       }     }   }); </script>

NOTE:

The breakpoints behave like (min-width: breakpoint) in CSS, so an undefined option will be inherited from previous small breakpoints.
fixedWidth can only be changed to other positive integers. It can't be changed to negative integer, 0 or other data type. top↑^[20]

Methods

The slider returns a slider object with some properties and methods once it's initialized:

{   version: version, // tiny-slider version   getInfo: info(),   events: events, // Object   goTo: goTo(),   play: play(),   pause: pause(),   isOn: isOn, // Boolean   updateSliderHeight: updateInnerWrapperHeight(),   refresh: initSliderTransform(),   destroy: destroy(),   rebuild: rebuild() }

To get the slider information, you can either use the getInfo() method or subscribe to an Event. Both return an Object:

{                 container: container, // slider container                slideItems: slideItems, // slides list              navContainer: navContainer, // nav container                  navItems: navItems, // dots list         controlsContainer: controlsContainer, // controls container               hasControls: hasControls, // indicate if controls exist                prevButton: prevButton, // previous button                nextButton: nextButton, // next button                     items: items, // items on a page                   slideBy: slideBy // items slide by                cloneCount: cloneCount, // cloned slide count                slideCount: slideCount, // original slide count             slideCountNew: slideCountNew, // total slide count after initialization                     index: index, // current index               indexCached: indexCached, // previous index              displayIndex: getCurrentSlide(), // display index starts from 1                navCurrent: navCurrent, // current dot index          navCurrentCached: navCurrentCached, // previous dot index                     pages: pages, // visible nav indexes               pagesCached: pagesCached,                     sheet: sheet,                     event: e || {}, // event object if available };

getInfo

Get slider information.

slider.getInfo();  document.querySelector('.next-button').onclick = function () {   // get slider info   var info = slider.getInfo(),       indexPrev = info.indexCached,       indexCurrent = info.index;    // update style based on index   info.slideItems[indexPrev].classList.remove('active');   info.slideItems[indexCurrent].classList.add('active'); };

goTo

Go to specific slide by number or keywords.

slider.goTo(3); slider.goTo('prev'); slider.goTo('next'); slider.goTo('first'); slider.goTo('last');  document.querySelector('.goto-button').onclick = function () {   slider.goTo(3); };

play

Programmatically start slider autoplay when autoplay: true.

pause

Programmatically stop slider autoplay when autoplay: true.

updateSliderHeight

Manually adjust slider height when autoHeight is true.

slider.updateSliderHeight();

destroy

Destroy the slider.

rebuild

Rebuild the slider after destroy.

slider = slider.rebuild(); // this method returns a new slider Object with the same options with the original slider

Custom Events

Available events include: indexChanged, transitionStart, transitionEnd, newBreakpointStart, newBreakpointEnd, touchStart, touchMove, touchEnd, dragStart, dragMove and dragEnd.

var customizedFunction = function (info, eventName) {   // direct access to info object   console.log(info.event.type, info.container.id); }  // bind function to event slider.events.on('transitionEnd', customizedFunction);  // remove function binding slider.events.off('transitionEnd', customizedFunction);
