WeChat applet multi-layer nested rendering list and data acquisition code

The content of this article is about the code for multi-layer nested rendering lists and data acquisition of WeChat mini programs. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

Cause: The intention is to achieve an effect similar to Android viewpager, and I thought of using the swiper component of the WeChat applet, but if only one wx:for is used in each swiper-item to render Data is really too slow, so I thought of multi-layer nested data rendering to improve efficiency.

Go directly to the code

wxml:

<view>
  <view>----{{item.name}}----</view>
  <view>

    <view>----{{two.name}}----</view>
  </view>
  <view>
    ----{{three.name}}----
  </view>

        }, {
          'id': 12,
            'name': '第二层第二个数据'

        three: [{
          'name': '第三层数据'

        name: '第二次渲染第一层',
        two: [{
