本文实例为大家分享了微信小程序自定义轮播图展示的具体代码，供大家参考，具体内容如下

默认的swiper面板指示点都是小圆点黑灰的，但这满足不了广大小伙伴需求，比如其他颜色的，椭圆形的，方形的等等。

首先当然是要禁用掉（直接删掉）swiper属性indicator-dots，再用view组件模拟dots，对应的代码如下：

<view class="swiper-container"> <swiper autoplay="auto" interval="5000" duration="500" current="{{swiperCurrent}}" bindchange="swiperChange" class="swiper"> <block wx:for="{{slider}}" wx:key="unique">  <swiper-item>  <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' : ''}}"></view> </block> </view></view>

然后是wxss代码：

swiper-container{ position: relative;}.swiper-container .swiper{ height: 300rpx;}.swiper-container .swiper .img{ width: 100%; height: 100%;}.swiper-container .dots{ position: absolute; left: 0; right: 0; bottom: 20rpx; display: flex; justify-content: center;}.swiper-container .dots .dot{ margin: 0 8rpx; width: 14rpx; height: 14rpx; background: #fff; border-radius: 8rpx; transition: all .6s;}.swiper-container .dots .dot.active{ width: 24rpx; background: #f80;}

再对swiper的bindchange属性绑定对应的事件：

Page({data: { slider: [ {picUrl: '../../images/T003R720x288M000000rVobR3xG73f.jpg'}, {picUrl: '../../images/T003R720x288M000000j6Tax0WLWhD.jpg'}, {picUrl: '../../images/T003R720x288M000000a4LLK2VXxvj.jpg'}, ], swiperCurrent: 0,},swiperChange: function(e){ this.setData({  swiperCurrent: e.detail.current })}})

效果图：
