本文实例为大家分享了微信小程序轮播图的具体代码，供大家参考，具体内容如下

1.逻辑层

mine.js


// pages/mine/mine.js
Page({
 /**
 * 页面的初始数据
 */
 data: {
 /*轮播图 配置*/
 imgUrls: [
 'http://img02.tooopen.com/images/20150928/tooopen_sy_143912755726.jpg',
 'http://img06.tooopen.com/images/20160818/tooopen_sy_175866434296.jpg',
 'http://img06.tooopen.com/images/20160818/tooopen_sy_175833047715.jpg'
 ],
 indicatorDots: true, // 是否显示面板指示点
 autoplay: true, // 是否自动切换
 interval: 5000, // 自动切换时间间隔
 duration: 500, // 滑动动画时长
 circular: true, // 是否采用衔接滑动
 /*自定义轮播图 配置*/
 slider: [
 { id: '0', linkUrl: 'pages/index/index', picUrl: 'http://img02.tooopen.com/images/20150928/tooopen_sy_143912755726.jpg' },
 { id: '0', linkUrl: 'pages/index/index', picUrl: 'http://img06.tooopen.com/images/20160818/tooopen_sy_175866434296.jpg' },
 { id: '0', linkUrl: 'pages/index/index', picUrl: 'http://img06.tooopen.com/images/20160818/tooopen_sy_175833047715.jpg' }
 ],
 swiperCurrent: 0
 },
 /**
 * 生命周期函数--监听页面加载
 */
 onLoad: function (options) {
 },
 //轮播图的切换事件 
 swiperChange: function (e) {
 //只要把切换后当前的index传给<swiper>组件的current属性即可 
 this.setData({
 swiperCurrent: e.detail.current
 })
 },
 //点击指示点切换 
 chuangEvent: function (e) {
 this.setData({
 swiperCurrent: e.currentTarget.id
 })
 }
})

2.页面布局

mine.wxml


<!--pages/mine/mine.wxml-->
<view>
 <!-- 轮播图 -->
 <swiper class="swiper" indicator-dots="{{indicatorDots}}"
 autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}" circular="{{circular}}">
 <block wx:for="{{imgUrls}}" wx:key="id">
 <swiper-item>
 <image src="{{item}}" class="slide-image" />
 </swiper-item>
 </block>
 </swiper>
 <!-- 自定义轮播图 -->
 <view class="swiper-container"> 
 <swiper circular="true" autoplay="auto" interval="5000" duration="500" current="{{swiperCurrent}}" bindchange="swiperChange" class="swiper"> 
 <block wx:for="{{slider}}" wx:key="unique"> 
 <swiper-item data-id="{{item.id}}" data-url="{{item.linkUrl}}"> 
  <image src="{{item.picUrl}}" class="img"></image> 
 </swiper-item> 
 </block> 
 </swiper> 
 <view class="dots"> 
 <block wx:for="{{slider}}" wx:key="unique"> 
 <view class="dot{{index == swiperCurrent ? ' active' : ''}}" bindtap="chuangEvent" id="{{index}}">{{index+1}}</view> 
 </block> 
 </view> 
 </view>
</view>

3.样式

mine.wxss
