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;
},
},
})Initial value:
