swiper触摸之后不会自动轮播了 解决办法

var mySwiper = new Swiper('.actJp', {
    loop: true,
    autoplay: {
        delay: 800,
    },
    slidesPerView: 4.2,
    spaceBetween: 10,
    autoplayDisableOnInteraction : false, //如果这个无效
    on: {
        slideChangeTransitionEnd: function() {
            this.autoplay.start();//就加这句手动滑动后再轮播
        },
    }
});
