身份证，港澳通行证，台胞证，记一下三个常用的正则判断

正则判断

    15: '内蒙古',
    21: '辽宁',
    22: '吉林',

解析身份证，判断生日，性别，年龄

// 解析身份证信息
export function parseIdCard(value: string): any {
  let birthday, sex, age;
  if (checkIdCard(value)) {
    birthday = `${value.substring(6, 10)}-${value.substring(
      10,
      12
    )}-${value.substring(12, 14)}`;
    sex = parseInt(value.substr(16, 1)) % 2 == 1 ? '1' : '2';

    const myDate = new Date();
    const month = myDate.getMonth() + 1;
    const day = myDate.getDate();
    age = myDate.getFullYear() - value.substring(6, 10) - 1;
    if (
      value.substring(10, 12) < month ||
      (value.substring(10, 12) == month && value.substring(12, 14) <= day)
    ) {
      age++;
    }
  }

  return { birthday, sex, age };
