Question

我想在wl carousel 2（本机）中找到center项，而不是像class那样被$('.owl-item.center')选择，我想通过owl carousel本机函数和结果来查找它我可以获得事件，并且有很多结果，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!');
  }
});

我该如何在本地检测猫头鹰轮播2中心项目？再次，我不想使用center find或任何其他选择器通过each类通过jquery查找项目，我想用猫头鹰给我。

我不认为猫头鹰传送带提供了这样的选项来获取事件结果中的中心项目。您可以像这样稍微棘手，仅将e.item.index设为当前活动项，然后+1以获得居中项。查看下面的示例：

$('.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="owl-carousel">
  <div class="item">

  <div class="item">
    <h4>2</h4>
  </div>
  <div class="item">
    <h4>3</h4>
  </div>
  <div class="item">
    <h4>4</h4>
  </div>
  <div class="item">
    <h4>5</h4>
  </div>
  <div class="item">
