原因是现在自动播放的代码和其他属性不是平级的，要另外写一个，例如
//自动播放的关键
autoplay: {
delay: 2500,
disableOnInteraction: false,
},
--------------------------------------------------
var galleryTop = new Swiper('.gallery-top', {
spaceBetween: 10,
loop:true,
loopedSlides: 5, //looped slides should be the same
navigation: {
nextEl: '.swiper-button-next',
prevEl: '.swiper-button-prev',
},
//自动播放的关键
autoplay: {
delay: 2500,
disableOnInteraction: false,
},
});
