如：
<div id="carouselExampleCaptions001" class="carousel slide" data-ride="carousel"> <div class="carousel-inner" style="height: 100%;"> <div class="carousel-item active" > <img src="img/page4-swiper07.png" > </div> <div class="carousel-item" > <img src="img/page4-swiper09.png" > </div> <div class="carousel-item" > <img src="img/page4-swiper04.png" > </div> <div class="carousel-item" > <img src="img/page4-swiper06.png" > </div> </div> </div>
$(‘#carouselExampleCaptions‘).on(‘slide.bs.carousel‘, function (event) { var $hoder = $(‘#carouselExampleCaptions‘).find(‘.carousel-item‘), $items = $(event.relatedTarget); //getIndex就是轮播到当前位置的索引 var getIndex= $hoder.index($items); console.log(getIndex) })
