⼩程序实现Swiper轮播图效果本⽂实例为⼤家分享了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: [
'pen/images/20150928/tooopen_sy_143912755726.jpg',
'pen/images/20160818/tooopen_sy_175866434296.jpg',
'pen/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: 'pen/images/20150928/tooopen_sy_143912755726.jpg' }, { id: '0', linkUrl: 'pages/index/index', picUrl: 'pen/images/20160818/tooopen_sy_175866434296.jpg' }, { id: '0', linkUrl: 'pages/index/index', picUrl: 'pen/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">js实现轮播图最简代码
<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
