如何将全局变量中数组的每一个值依次赋值给page中的data，从而更新其初始数值？
我是小白，在切换页面时想让多个单选框组保留选中状态，于是将e.detail.value存储到全局变量数组中，
然后在onLoad函数中用this.setData依次赋值多个单选问题的value，然后判断value决定是否checked。
却发现第一个单选问题的value值是初始状态的赋值，全局变量无法赋值到page的data中；但是后面几个问题的value又赋值成功。
请教各位有什么简介易懂的方法，让第一个单选问题的value值能被全局变量赋值成功，或者实现切换页面时单选框组保留选中状态。
以下是部分js文件代码：
// 获取应用实例
const app = getApp()
//初始化
Page({
data: {
lastAnswers: ['?','?','?','?','?','?'],

{value: "1", name: '犬或者猫'},
{value: "2", name: '其他'}
