owl-carousel slider on drag and dot click not work

问题:

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;
}

Try this

//for drag use this event

mouseDrag: true,

//for dot click

note: Please replace this code in your custom navigation slider button

    <div class="owl-dots">
      <button role="button" class="owl-next own-custome-trigger">
        <span></span>
      </button>
      <button role="button" class="owl-prev own-custome-trigger">
        <span> </span>
      </button>
   </div>

//css for dots

.own-custome-trigger {
background: red;
display: inline-block;
height: 15px;
width: 15px;
border: 0;
border-radius: 50%;
margin-right: 5px;
cursor: pointer;

}

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.

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);

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')
});

o1.on('translate.owl.carousel', function(e) {
  o2.trigger('to.owl.carousel',e.page.index * o2settings.slideBy);
});
//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-dot span {
  display: block;
  height: 15px;
  width: 15px;
  background: #f00;
  border-radius: 30px;
}

.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;
}
