嗨！我在这个 owl-carousel 中遇到了一个延迟问题。 如您所见，此猫头鹰轮播在 6 秒后播放。

即使我将“autoplaySpeed”和“smartSpeed”更改为1000， 6 秒后它仍然播放。 那么有没有办法让它在开始时没有任何延迟地播放？

任何帮助将不胜感激！谢谢！ :D

解决方法

您必须使用 autoplayTimeout 属性。 此外，我添加了一个逻辑，它将在第一次渲染后更新 autoplayTimeout。

JS：

var $carousel = $(".owl-carousel");
$carousel.owlCarousel({
  loop: true,items: 1,autoplay: true,slideTransition: "linear",autoplayTimeout: 1000,/*(ms you want)*/
  loop: true,autoplayHoverPause: false,center: true,});

setTimeout(() => {
  var carouselData = $carousel.data();
  var carouselOptions = carouselData['owl.carousel'].options;
    carouselOptions.autoplayTimeout = 6000;
  $carousel.trigger('refresh.owl.carousel');
},1000);
