Data Attribute Settings

In slick 1.5 you can now add settings using the data-slick attribute. You still need to call $(element).slick() to initialize slick on the element.

Example:

1

2

3

4

Responsive Option Example

The responsive option, and value, is quite unique and powerful. You can use it like so:

$(".slider").slick({

// normal options... infinite: false,

// the magic responsive: [{

  breakpoint: 1024,
  settings: {
    slidesToShow: 3,
    infinite: true
  }

}, {

  breakpoint: 600,
  settings: {
    slidesToShow: 2,
    dots: true
  }

}, {

  breakpoint: 300,
  settings: "unslick" // destroys slick

}]

});

Events

In slick 1.4, callback methods were deprecated and replaced with events. Use them before the initialization of slick as shown below:

// On swipe event
$('.your-element').on('swipe', function(event, slick, direction){
  console.log(direction);
  // left
});

// On edge hit $('.your-element').on('edge', function(event, slick, direction){ console.log('edge was hit') });

// On before slide change $('.your-element').on('beforeChange', function(event, slick, currentSlide, nextSlide){ console.log(nextSlide); });

Event

Params Description
afterChange event, slick, currentSlide After slide change callback
beforeChange event, slick, currentSlide, nextSlide Before slide change callback
breakpoint event, slick, breakpoint Fires after a breakpoint is hit
destroy event, slick When slider is destroyed, or unslicked.
edge event, slick, direction Fires when an edge is overscrolled in non-infinite mode.
init event, slick When Slick initializes for the first time callback. Note that this event should be defined before initializing the slider.
reInit event, slick Every time Slick (re-)initializes callback
setPosition event, slick Every time Slick recalculates position
swipe event, slick, direction Fires after swipe/drag
lazyLoaded event, slick, image, imageSource Fires after image loads lazily
lazyLoadError event, slick, image, imageSource Fires after image fails to load

Methods

Methods are called on slick instances through the slick method itself in version 1.4, see below:

// Add a slide
$('.your-element').slick('slickAdd',"
");

// Get the current slide var currentSlide = $('.your-element').slick('slickCurrentSlide');

This new syntax allows you to call any internal slick method as well:

// Manually refresh positioning of slick
$('.your-element').slick('setPosition');
