1.异步设置data里面的值

方法：
  setDataAsync(opt) {
    return new Promise(resolve => {
      this.setData(opt, resolve)
    })
  }
调用：
 async onShow() {
    my.showLoading();
    try {
      const data = await apis.xxx();
      await this.setDataAsync({
        basicData: data,
        pageShow: true
      })
      apis.xxx();
    } catch (e) {

2.设置data里面的值中的key

data: {
   subData: {}
}
let infoList = ['address1','address2','address3']
      for (var i in infoList) {
        this.setData({
          [`subData[${infoList[i]}]`]: '',
        })
      }
