getInfo(idCard) {
        let sex = null;
        let birth = null;
        let myDate = new Date();
        let month = myDate.getMonth() + 1;

        let age = 0;

        if (idCard.length === 18) {

          birth = idCard.substring(6, 10) + "-" + idCard.substring(10, 12) + "-" + idCard.substring(12, 14);
          if (idCard.substring(10, 12) < month || idCard.substring(10, 12) === month && idCard.substring(12, 14) <= day)
            age++;

        }
        if (idCard.length === 15) {

            age++;
        }

        if (sex % 2 === 0)
          sex = 0; // 性别代码 1代表男，0代表女，暂时不涉及其他类型性别
        else
          sex = 1;
        return {
          age,
          sex,

getBirthday(idCard) {
        let birthday = "";
        if (idCard != null && idCard !== "") {

          } else if (idCard.length === 18) {
            birthday = idCard.substr(6, 8);
          }
          birthday = birthday.replace(/(.{4})(.{2})/, "$1-$2-");
        }
        return birthday;
