Owl-Carousel2 - set dotsData

Question

I need to set custom dots in owl carousel. I have this code in JS:

$(document).ready(function() {
  $('#header-slider').owlCarousel({
    loop: true,
    autoplay: true,
    autoplayTimeout: 2300,
    pagination: false,
    navigation: true,
    navText: [$('.am-next'), $('.am-prev')],
    navigation: true,
    margin: 0,
    dotsData: ["<button role='button' class='owl-dot'></button><svg version='1.1' xmlns='http://www.w3.org/2000/svg' xmlns:xlink='http://www.w3.org/1999/xlink' x='0px' y='0px' width='16' height='16' viewbox='0 0 250 250' enable-background='new 0 0 426.667 410' xml:space='preserve'><path class='loader' transform='translate(125, 125) scale(.84)'></svg>"],
    responsive: {
      0: {
        items: 1
      },
      600: {
        items: 1
      },
      1000: {
        items: 1,
        nav: false
      },
      1200: {
        items: 1,
        nav: false
      }
    }
  });
});

But with this code nothing happend, just undefined dots are displayed. Is even possible to make custom dots like this?

Solution 1

Change the following code like this:

$(document).ready(function() {
  $('#header-slider').owlCarousel({
    loop: true,
    autoplay: true,
    autoplayTimeout: 2300,
    pagination: false,
    navigation: true,
    navText: [$('.am-next'), $('.am-prev')],
    navigation: true,
    margin: 0,
    dotData: true,
    dotsData: true
    responsive: {
      0: {
        items: 1
      },
      600: {
        items: 1
      },
      1000: {
        items: 1,
        nav: false
      },
      1200: {
        items: 1,
        nav: false
      }
    }
  });
});

Add your dots data in your owl-item:

  <div class="item" data-dot="<button role='button' class='owl-dot'></button>">
     <!-- Your Image -->
  </div>

Solution 2

So looking at the documentation, the dotsData option takes a boolean which just tells Owl Carousel to look for the data-dot attribute for each item a dot is shown for. So your custom markup needs to go into the HTML rather than being passed in as a string when configuring the carousel in JS.

If you check this Fiddle you can see how the JS option relates to the HTML data attribute: https://jsfiddle.net/4xymnwey/

HTML

<ul class="owl-carousel owl-theme">
  <li class="carousel-slot" data-dot="<p>text 1</p>">slide 1</li>
  <li class="carousel-slot" data-dot="<p>text 2</p>">slide 2</li>
  <li class="carousel-slot" data-dot="<p>text 3</p>">slide 3</li>
</ul>

JS

$(".owl-carousel").owlCarousel({
  items: 1,
  dots: true,
  dotsData: true
});
