假设当前显示的是1，往左滑动一个递减1，往右滑动一个递增1

body下面添加如下代码

<div class="swiper-container temp"> <div class="swiper-wrapper">  <div class="swiper-slide">   1  </div>  <div class="swiper-slide">   2  </div>  <div class="swiper-slide">   3  </div> </div></div>

引用swiper的css和js脚本(当前使用的是4.x以上版本)

添加js脚本

var now_ActiveIndex=2;//,//当前所在下标var tempSwiper = new Swiper('.swiper-container.temp', { initialSlide: 1, loop:true, speed:400, on: {  slideChange: function(swiper){//当当前Slide切换时执行(activeIndex发生改变)   var pre_number=Number($(this.slides[now_ActiveIndex]).text());   if(now_ActiveIndex>this.activeIndex){    if(now_ActiveIndex==4&&this.activeIndex==1){     $(this.slides[this.activeIndex]).text(pre_number);    }else{//上一个     var act_number=pre_number-1;     $(this.slides[this.activeIndex]).text(act_number);    }   }else if(now_ActiveIndex<this.activeIndex){    if(now_ActiveIndex==0&&this.activeIndex==3){     $(this.slides[this.activeIndex]).text(pre_number);    }else{//下一个     var act_number=pre_number+1;     $(this.slides[this.activeIndex]).text(act_number);    }   }   now_ActiveIndex=this.activeIndex;  }, },})
