Hello
swiperOptionA: {
lazy: true,
slidesPerView: 4,
spaceBetween: 8,
loop: true,
centeredSlides: true,
Centered slides which are lazily loaded, with no white space on left at the start
Images added by 'loop' are not lazy loaded, screenshot - https://imgur.com/a/A4P3FSl , if I continue one slide to left, just middle one gets loaded (screen https://imgur.com/a/tN8bU1c).
loop functionality is duplicating only DOM nodes, meaning that your duplicated slides for the loop don't have their JS code appended as well, only the rendered result.
I spent 2 days trying to figure this out, so by using the original Swiper's methods and events, I came to a semi-infinite-loop feature:
add the following to your swiper's config
loop: true,
loopedSlides: 1,
on: {
slideChange: function () {
let lastVisibleItem = this.realIndex + this.params.slidesPerView
let slidesLength = this.slides.length - 2
let lastVisibleIndex = this.realIndex + this.params.slidesPerView
// if swiper reaches the end of displayed items, goToNext redirects swiper to the start
if (lastVisibleItem > slidesLength) {
this.slideTo(1)
}
// if swiper wants to go before the first item, then forward swiper to the last item
if (lastVisibleIndex >= this.slides.length) {
this.slideTo((slidesLength - this.params.slidesPerView) + 1)
}
}
}
