What is the best way to refresh an owl-carousel element?

Currently, I am utilizing the owl-carousel-2 plugin for my project.

However, I have come across a particular issue:

The coding structure:

<div class="owl-carousel" style="display: none;">
    <div class="item"><img src="..." /></div>
    <div class="item"><img src="..." /></div>
    <!-- ... -->
    <div class="item"><img src="..." /></div>
</div>

<script>
$(function() {
    var $owl = $('.owl-carousel');
    $owl.owlCarousel();

    // Various operations performed here.

    $owl.show();
});
</script>

The issue at hand:

Upon initializing with the $owl.owlCarousel(); command while being hidden, the sizing does not get properly initialized.

Hence, upon displaying the control, everything appears scrambled!

Surprisingly, when the window is resized, some sort of re-rendering occurs. This results in a proper display of content.

I am pondering if there exists a method to manually trigger this re-render (or refresh) process.

This action will ensure that the control displays correctly without any mess.

Despite attempting to study the documentation and sources available, I have yet to discover a satisfactory solution.

Your assistance on this matter would be greatly appreciated.

Answer №1

I came across a less than ideal solution, but it managed to do the trick:

Primary method:

  1. Eliminate the owl-carousel.
  2. Manually restore the original layout.
  3. Reinitialize the owl-carousel.
var $owl = $('.owl-carousel');
$owl.trigger('destroy.owl.carousel');
// Even after destruction, the structure remains altered.
// The disparities include:
//   1. The initial content was enclosed within 'div.owl-stage-outer';
//   2. The '.owl-carousel' itself carries an attached '.owl-loaded' class;
//   Prior to reinitialization, we must eliminate these deviations.
$owl.html($owl.find('.owl-stage-outer').html()).removeClass('owl-loaded');
$owl.owlCarousel({
    // insert your starting options here once more.
});

This approach worked, albeit in a rather messy manner. I am eagerly anticipating encountering a cleaner, improved resolution.

Answer №2

I found a solution that works well for me:

// locate owl element
var owl = $('.owl-carousel');

// retrieve owl instance from the element
var owlInstance = owl.data('owlCarousel');

// check if instance exists
if(owlInstance !== null)
    owlInstance.reinit();

Answer №3

After some research and experimentation, I have come up with a solution inspired by fish_ball's brilliant workaround:

if($('.owl-carousel').hasClass('owl-theme')){ //To avoid triggering an error during the resize event

            $('.owl-carousel').trigger('destroy.owl.carousel'); //These lines essentially reset the owl carousel
            $('.owl-carousel').find('.owl-stage-outer').children().unwrap();
            $('.owl-carousel').removeClass("owl-center owl-loaded owl-text-select-on");

            $(".owl-carousel").owlCarousel(); //Reinitializing the owl carousel
        }

Answer №4

Encountered a similar issue like the one with OP. I was able to resolve it by removing the owl-loaded class first. Then, upon rendering, I initiated a refresh event once the class was added back.

// Remove the owl-loaded class post initialization 
$owl.owlCarousel().removeClass('owl-loaded');

// Display the carousel and trigger the refresh
$owl.show(function() {
  $(this).addClass('owl-loaded').trigger('refresh.owl.carousel');
})

Answer №5

Here's a solution that has been effective for me with version 2.0.0-beta.2.4:

const $carousel = $('.owl-carousel');
if ($carousel.data('owlCarousel')) {
    $carousel.data('owlCarousel').onThrottledResize();
}

Answer №6

To reinitialize Owl Carousel 2, use the following code snippet:

jQuery('.owl-carousel').trigger('refresh.owl.carousel');

For more information, check out this problem report.

Answer №7

Make sure to review the documentation for the plugin you are utilizing, as the owl carousel provides a refresh method for updating the carousel.

refresh.owl.carousel

Type: attachable, cancelable, triggerable
Callback: onRefresh
Parameter: [event, speed]

Check out the documentation for more details on events
