微信小程序自定义轮播图swiper dots默认样式

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：

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
    })
}
})
