$('#carousel-example-generic').on('slide.bs.carousel', function (event) {
            var $hoder = $('#carousel-example-generic').find('.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,'===111===')
        })
