Swiper js, reset currentTime to 0 slide`s video

Question

I am trying to set currentTime = 0 to the slides with video when the slider is in a image slide.

Its possible with swiper js?

The actual js:

var swiper = new Swiper('.swiper-container', {
  pagination: '.swiper-pagination',
  paginationClickable: true,
  nextButton: '.swiper-button-next',
  prevButton: '.swiper-button-prev',
  spaceBetween: 30,
  autoplayDisableOnInteraction: true,
    speed: 1000,
   autoplay: true,
});

Answer 1

First reset and autoplay video not related to swiper API - use simple JS:

stackoverflow: How to Reset video using html5

You should use Swiper API events:

mySwiper.on('slideChange', function () {
  console.log('slide changed do something');
});

• swiper-API-events: https://swiperjs.com/api/#events

• You should muted video with sound (Otherwise the autoplay will not work on chrome): https://www.w3schools.com/tags/att_video_muted.asp

update answer (Full code example)

• Remove "autoplay" from all videos.
• jquery require
• The first video play under init event
• The prev video and current video play/stop under slideChange event
• I use var inside Jquery selector to get the prev/current video - read more her: stackoverflow: How to use JavaScript variables in jQuery selectors?

var swiper = new Swiper('.swiper', {
  loop: true,
  pagination: {
    el: '.swiper-pagination',
    clickable: true
  },
  navigation: {
    nextEl: '.swiper-button-next',
    prevEl: '.swiper-button-prev',
  },

  /* ON INIT AUTOPLAY THE FIRST VIDEO */
  on: {
    init: function () {
      console.log('swiper initialized');
      var currentVideo =  $("[data-swiper-slide-index=" + this.realIndex + "]").find("video");
      currentVideo.trigger('play');
    },
  },
});

/* GET ALL VIDEOS */
var sliderVideos = $(".swiper-slide video");

/* SWIPER API - Event will be fired after animation to other slide (next or previous) */
swiper.on('slideChange', function () {
  console.log('slide changed');
  /* stop all videos (currentTime buggy without this loop idea) */
  sliderVideos.each(function( index ) {
    this.currentTime = 0;
  });

  /* SWIPER GET CURRENT AND PREV SLIDE (AND VIDEO INSIDE) */
  var prevVideo =  $("[data-swiper-slide-index=" + this.previousIndex + "]").find("video");
  var currentVideo =  $("[data-swiper-slide-index=" + this.realIndex + "]").find("video");
  prevVideo.trigger('stop');
  currentVideo.trigger('play');
});
