Owl 轮播 2 找到中心项目

Question

我想在 owl carousel 2（本机）中找到 center 项，而不是 class select 就像 $('.owl-item.center') 我想找到它通过 owl 轮播本机函数和结果，现在我可以获得事件，并且有一堆结果，我可以获得与 center

相关的任何值

$('.owl-carousel').owlCarousel({
  center: true,
  items: 3,
  loop: false,
  margin: 10,
});

$('.owl-carousel').on("dragged.owl.carousel", function(e) {
  console.log(e);
  if (e.itemClass === 'center') {
    alert('it is center one!');
  }
});

<div class="owl-carousel">

  <div class="item">
    <h4>4</h4>
  </div>
  <div class="item">
    <h4>5</h4>
  </div>
  <div class="item">
    <h4>6</h4>

</div>

如何检测 owl carousel 2 center item in native？同样，我不想通过 center class 和 find each 或任何其他 select 查找 jquery 查找项目，或者，我想要owl 给我。

Answer 1

我不认为 owl 轮播提供这样的选项来获得事件结果中的中心项目。你可以像这样有点棘手地做这件事，只需要 e.item.index 它是当前活动的项目，然后 +1 来获得居中的项目。检查下面的示例：

$('.owl-carousel').owlCarousel({
  center: true,
  items: 3,
  loop: false,
  margin: 10,
});

$('.owl-carousel').on("dragged.owl.carousel", function(e) {
  console.log('center item is:'+ (e.item.index + 1));
});

.item {
  border: 1px solid;
  text-align: center;
}

.owl-item.active.center {
  background: gray;
}

  <div class="item">

  <div class="item">
