Today, I record how to achieve the effect of the rotation chart when developing the small program. Not much to say, go directly to the code:

<!-- 1. Home Rotary Map -->
  <view>
    <swiper class="my-swiper" 
              autoplay="true" 
              indicator-dots="true" 
              indicator-active-color="#fff"
              circular="true">
        <block wx:for="{{imgUrls}}">
          <swiper-item class="sw-img">
              <image src="{{item}}" mode="widthFix"></image>
          </swiper-item>
        </block>
      </swiper>
  </view>

Rotation, using swiper components, there are many attributes, generally the following are more commonly used:

• autoplay="true": Set autoplay
• indicator-dots="true": Whether the panel pointer is displayed or not
• indicator-active-color="#fff": the current selected indicator color
• circular="true": whether to use cohesive sliding
• Interval: automatic switching interval, default 5000ms

Data in js:

Page({
  data: {
    imgUrls: ["https://picabstract-preview-ftn.weiyun.com/ftn_pic_abs_v3/3c5e6138079dc63ebe3688afff0a63b0fb56fbe1702bb754e33c4ca874b872ced8df2f995cd0d7ae9ce9db487f8f90a7?pictype=scale&from=30013&version=3.3.3.3&uin=522083376&fname=Natural.png&size=750",
