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> <swiper autoplay="auto" interval="5000" duration="500" current="{{swiperCurrent}}" bindchange="swiperChange"> <block wx:for="{{slider}}" wx:key="unique"> <swiper-item> <image src="https://www.jb51.net/{{item.picUrl}}"></image> </swiper-item> </block> </swiper> <view> <block wx:for="{{slider}}" wx:key="unique"> <view></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：
