owl-carousel 2同步自定义

Question

I'm using Two owl carousel sliders with one navigation for my bootstrap website. In the below code prev and next is working perfectly.

The problem that the ondrag and owl-dots functions are not working. When I click the dot and drag the first slider ( work-class1 ) the second slider should slide same like prev and next arrow.

 var o2 = $('#work-class2') o2.owlCarousel({ items: 2, singleItem: true, loop: false, margin: 10, dots: false, pagination: false, nav: false, touchDrag: true, slideBy: 2, mouseDrag: false }); var o1 = $('#work-class1'); o1.owlCarousel({ items: 1, singleItem: true, loop: false, margin: 0, //dots:false, pagination: false, nav: true, touchDrag: true, slideBy: 1, mouseDrag: true }); var o1 = $('#work-class1'), o2 = $('#work-class2'); //Sync o2 by o1 o1.on('click onDragged', '.owl-next', function() { o2.trigger('next.owl.carousel') }); o1.on('click dragged.owl.carousel', '.owl-prev', function() { o2.trigger('prev.owl.carousel') }); //Sync o1 by o2 o2.on('click onDragged', '.owl-next', function() { o1.trigger('next.owl.carousel') }); o2.on('click dragged.owl.carousel', '.owl-prev', function() { o1.trigger('prev.owl.carousel') }); 

 .owl-carousel .owl-nav button.owl-next span, .owl-carousel .owl-nav button.owl-prev span, .owl-carousel button.owl-dot { font-size: 40px; margin: 0 10px; } .owl-dot span { display: block; height: 15px; width: 15px; background: #f00; border-radius: 30px; }

Answer 1

You can listen to changed.owl.carousel event and then trigger to.owl.carousel to sync the carousels on click , scroll and drag :

// sync o2 on o1
o1.on('changed.owl.carousel', function(event) {
  o2.trigger('to.owl.carousel', [event.item.index == 0 ? 0 : 2]);
});

Note the calculation of indices depend on the no of items in the first and second carousel. See demo below and a codepen to fiddle with:

 var o2 = $('#work-class2') o2.owlCarousel({ items: 2, singleItem: true, loop: false, margin: 10, dots: false, pagination: false, nav: false, touchDrag: true, slideBy: 2, mouseDrag: false }); var o1 = $('#work-class1'); o1.owlCarousel({ items: 1, singleItem: true, loop: false, margin: 0, //dots:false, pagination: false, nav: true, touchDrag: true, slideBy: 1, mouseDrag: true }); var o1 = $('#work-class1'), o2 = $('#work-class2'); // sync o2 on o1 o1.on('changed.owl.carousel', function(event) { o2.trigger('to.owl.carousel', [event.item.index == 0 ? 0 : 2]); }); 

 .owl-carousel .owl-nav button.owl-next span, .owl-carousel .owl-nav button.owl-prev span, .owl-carousel button.owl-dot { font-size: 40px; margin: 0 10px; } .owl-dot span { display: block; height: 15px; width: 15px; background: #f00; border-radius: 30px; }

Answer 2

Here's something that works for what you need. Basically, just changed the second carousel options into an object and referenced that to determine how many slides to switch the secondary carousel by with a translate.owl.carousel call. It's also easily extendable should you want to add more slides into the secondary carousel.

var o2 = $('#work-class2')
var o2settings = {
  items: 2,
  singleItem: true,
  loop: false,
  margin: 10,
  dots: false,
  pagination: false,
  nav: false,
  touchDrag: true,
  slideBy: 2,
  mouseDrag: false
};
o2.owlCarousel(o2settings);

o1.on('translate.owl.carousel', function(e) {
  o2.trigger('to.owl.carousel',e.page.index * o2settings.slideBy);
});
