 var mySwiper = new Swiper('.swiper-container', {
                        // initialSlide :-3,
                        speed: 800,
                        slidesPerView: 5,
                        spaceBetween: 0,
                        freeMode: true,
                        autoplay: 600,
                        observer:true,//修改swiper自己或子元素时，自动初始化swiper
                        observeParents:true,//修改swiper的父元素时，自动初始化swiper
                        loop:true,
                        loopedSlides:  1,
                        autoplayDisableOnInteraction:false,
                    });
