How to create a progress bar for Owl Carousel 2?

Question

The official senior link for the Owl 1 development panel does not even work, but I found an example work , but also for Owl 1.

I tried to use the code, but I can not configure it to work with Owl 2 http://codepen.io/anon/pen/GrgEaG

$(document).ready(function() {

  var time = 7; // time in seconds

  var $progressBar,
      $bar, 
      $elem, 
      isPause, 
      tick,
      percentTime;

    //Init the carousel
    $("#owl-demo").owlCarousel({
      items: 1,
      initialized : progressBar,
      translate : moved,
      drag : pauseOnDragging
    });

    //Init progressBar where elem is $("#owl-demo")
    function progressBar(elem){
      $elem = elem;
      //build progress bar elements
      buildProgressBar();
      //start counting
      start();
    }

    //create div#progressBar and div#bar then prepend to $("#owl-demo")
    function buildProgressBar(){
      $progressBar = $("<div>",{
        id:"progressBar"
      });
      $bar = $("<div>",{
        id:"bar"
      });
      $progressBar.append($bar).prependTo($elem);
    }

    function start() {
      //reset timer
      percentTime = 0;
      isPause = false;
      //run interval every 0.01 second
      tick = setInterval(interval, 10);
    };

    function interval() {
      if(isPause === false){
        percentTime += 1 / time;
        $bar.css({
           width: percentTime+"%"
         });
        //if percentTime is equal or greater than 100
        if(percentTime >= 100){
          //slide to next item 
          $elem.trigger('owl.next')
        }
      }
    }

    //pause while dragging 
    function pauseOnDragging(){
      isPause = true;
    }

    //moved callback
    function moved(){
      //clear interval
      clearTimeout(tick);
      //start again
      start();
    }

    //uncomment this to make pause on mouseover 
    // $elem.on('mouseover',function(){
    //   isPause = true;
    // })
    // $elem.on('mouseout',function(){
    //   isPause = false;
    // })

});

#bar{
  width: 0%;
  max-width: 100%;
  height: 4px;
  background: #7fc242;
}
#progressBar{
  width: 100%;
  background: #EDEDED;
}

Answer 1

callback functions do not start because you call them on events that do not exist in owlCarousel 2. Events are prefixed with 'on'.

So, if you call them like this:

$("#owl-demo").owlCarousel({
  items: 1,
  onInitialized : progressBar,
  onTranslate : moved,
  onDrag : pauseOnDragging
});

. owlCarousel .

this CodePen progressbar OwlCarousel CSS.

, , , owl- v1.

v2.3.3, , js/css-:

JavaScript:

const $slider = $('.my-slider')
const SLIDER_TIMEOUT = 10000

$slider.owlCarousel({
  items: 1,
  nav: false,
  dots: false,
  autoplay: true,
  autoplayTimeout: SLIDER_TIMEOUT,
  autoplayHoverPause: true,
  loop: true,
  onInitialized: ({target}) => {
    const animationStyle = `-webkit-animation-duration:${SLIDER_TIMEOUT}ms;animation-duration:${SLIDER_TIMEOUT}ms`
    const progressBar = $(
      `<div class="slider-progress-bar"><span class="progress" style="${animationStyle}"></span></div>`
    )
    $(target).append(progressBar)
  },
  onChanged: ({type, target}) => {
    if (type === 'changed') {
      const $progressBar = $(target).find('.slider-progress-bar')
      const clonedProgressBar = $progressBar.clone(true)

      $progressBar.remove()
      $(target).append(clonedProgressBar)
    }
  }
})

.slider-progress-bar {
  /* your progress bar styles here */

  .progress {
    height: 4px;
    background: red;
    animation: sliderProgressBar ease;
  }
}

.my-slider:hover {
  .slider-progress-bar .progress {
    animation-play-state: paused;
  }
}

@keyframes sliderProgressBar {
  0% {
    width: 0%;
  }

  100% {
    width: 100%;
  }
}
