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) {

if (num == 1) {

//获取出生日期

let birth = card.substring(6, 10) + "-" + card.substring(10, 12) + "-" + card.substring(12, 14);

return birth;

}

if (num == 2) {

//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++;

}

return age;

}

}

/** 小程序或VUE框架加入下面这句*/

module.exports = {

getAnalysisIdCard: getAnalysisIdCard

}
