📚API详解 使用案例

📚示例代码

//获取省市县的JSON字符串
let txtStr = await AreaHelper.getAreaStr();
let areaList = JSONUtil.jsonToArray<AreaEntity>(txtStr);


//获取省市县的数据
let areas = AreaHelper.getAreaSync();


//根据省名获取下面的市
let citys = await AreaHelper.getCityByName("安徽省");


//根据市名获取下面的区县
let list = AreaHelper.getDistrictByNameSync("合肥市");


//配合‘@pura/harmony-dialog’的\nshowTextPickerDialog()方法使用
let data = AreaHelper.getAreaSync();
DialogHelper.showTextPickerDialog({
  title: "请选择",
  range: data,
  onChange: (value: string | string[], index: number | number[]) => {
    LogUtil.error(`value: ${value} --- index: ${index}`);
  },
  onAction: (action: number, dialogId: string, value: string | string[]) => {
    if (action === DialogAction.SURE) {
