根据身份证计算年龄

const getIdcardAge = (UUserCard) => {//计算身份证年龄

    (UUserCard + '' ).substring(6, 10) + "-" + (UUserCard + '' ).substring(10, 12) + "-" + (UUserCard + '' ).substring(12, 14)

    //获取年龄

    var myDate = new Date();

    var month = myDate.getMonth() + 1;

    var day = myDate.getDate()

    var age = myDate.getFullYear() - (UUserCard + '' ).substring(6, 10) - 1

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

        age++

    }

    return age

  }
