js 微信小程序根据身份证号计算年龄

封装成js文件

function getAge(identify) {var UUserCard = identify;if (UUserCard != null && UUserCard != '') {//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;//}}export {getAge}

页面引入

使用

let age = getAge(‘身份证号’);
