微信小程序使用swiper组件实现层叠轮播图

<view class="banner-swiper">
 <swiper indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" current='{{swiperCurrent}}' 
indicator-color="{{beforeColor}}" indicator-active-color="{{afterColor}}" circular='{{circular}}' 
previous-margin="{{previousmargin}}" next-margin="{{nextmargin}}" bindchange="swiperChange" >
 <block wx:for="{{arr}}" wx:key="key"> 
  <swiper-item>
  <image src="/UploadFiles/2021-04-02/{{item.images}}">

wxss:


.banner-swiper {
 width: 100%;
 height: 500rpx;
 overflow: hidden;
}

swiper {
 display: block;
 height: 500rpx;
 position: relative;
}

.slide-image {
 width: 96%;
 display: block;
 margin: 0 auto;
 height: 450rpx;
 margin-top:25rpx;
}
.active{
 margin-top:0rpx;
 height: 500rpx;
}



js:


Page({
 data: {
 //轮播图
 swiperCurrent:1,
 arr: [{
 images: 'images/1.jpg'
 },
 {
 images: 'images/5.jpg'
 },
 {
 images: 'images/3.jpg'
 },
 {
 images: 'images/4.jpg'
 }
 ]
 indicatorDots: true,
 autoplay: true,
 interval: 2000,
 duration: 1000,
 circular: true,
 beforeColor: "white",//指示点颜色 
 afterColor: "coral",//当前选中的指示点颜色 
 previousmargin:'30px',//前边距
 nextmargin:'30px',//后边距
 
 },
 
 //轮播图的切换事件 
 swiperChange: function (e) {
 console.log(e.detail.current);
 this.setData({
 swiperCurrent: e.detail.current //获取当前轮播图片的下标
 })
 },
 //滑动图片切换 
 chuangEvent: function (e) { 
 this.setData({
 swiperCurrent: e.currentTarget.id
 })
 },
})
