JS

var banner = require("../../src/js/banner.js");

Page({
  data: {
    isShowFrom1: false,
    isShowFrom2: false,
    isShowFrom3: false,
    indicatorDots: true,
    vertical: false,
    autoplay: true,
    interval: 3000,
    duration: 800,
    banner_url: banner.bannerList
  },
  onLoad: function (options) {

  },
  showFrom(e){
    var param = e.target.dataset.param; 
    this.setData({ 
      isShowFrom1: param == 1 ? (this.data.isShowFrom1 ? false : true) : false,
      isShowFrom2: param == 2 ? (this.data.isShowFrom2 ? false : true) : false,
      isShowFrom3: param == 3 ? (this.data.isShowFrom3 ? false : true) : false
    });
  }
})

Summary:
1. Each folding panel needs a Boolean value variable to control;
2. When the control details are hidden and displayed, the arrow on the right side should be switched correspondingly;
3. The optimization of the modified tridimensional expression of each boolean variable by showfrom function.
