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;
