如何检测最后一张幻灯片和第一张幻灯片？

Question

I am trying to detect the first slide and last slide using slick.js. https://github.com/kenwheeler/slick How can I do that?

Answer 1

There is couple of events you can use to detect this:

beforeChange

$('.slider').on('beforeChange', function(event, slick, currentSlide, nextSlide){
  console.log(nextSlide);
});

afterChange

$('.slider').on('afterChange', function(event, slick, currentSlide){
  console.log(currentSlide);
});

swipe

$('.slider').on('swipe', function(event, slick, direction){
  console.log(direction);
  // left
});

Let me know if this works for u.

Thanks
