cssEase

CSS3のアニメーションイージングを指定します。

• 初期値 : ease
• type : string

$('.slider').slick({
  cssEase: 'ease'
});

デモ

スライドのアニメーションをeaseにしています。 "ease-in"、"linear"ボタンを押すとアニメーションのイージングが変わります。

JavaScript

$(document).ready(function(){
  $('.slider').slick({
    cssEase: 'ease',
    autoplay: true,
    autoplaySpeed: 1000,
    speed: 2500,
  });
  $('.js-ease').on('click', function() {
    $('.slider').slick('slickSetOption', {
      cssEase: 'ease',
    });
  });
  $('.js-ease-in').on('click', function() {
    $('.slider').slick('slickSetOption', {
      cssEase: 'ease-in',
    });
  });
  $('.js-linear').on('click', function() {
    $('.slider').slick('slickSetOption', {
      cssEase: 'linear',
    });
  });
});
