js根据身份证号码解析获取出生年月日、性别、年龄

function getAnalysisIdCard(card, num) {

    //获取性别
    if (parseInt(card.substr(16, 1)) % 2 == 1) {
      //男
      return "男";
    } else {
      //女
      return "女";

    }
  }
  if (num == 3) {

    //获取年龄

    var myDate = new Date();

    var month = myDate.getMonth() + 1;

    var day = myDate.getDate();

    var age = myDate.getFullYear() - card.substring(6, 10) - 1;

    if (card.substring(10, 12) < month || card.substring(10, 12) == month && card.substring(12, 14) <= day) {

      age++;
