实现原理
通过控制详情部分的显示隐藏，来实现折叠效果，同时切换右侧向下箭头。

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
});
}
})总结：
1 每一个折叠面板需要一个布尔值变量来控制；
2 在控制详情隐藏和显示时，要将右侧的箭头对应切换；
3 showFrom函数对每一个布尔值变量的修改三目表达式的优化。
