公民身份号码是特征组合码，由十七位数字本体码和一位数字校验码组成。
排列顺序从左至右依次为：六位数字地址码，八位数字出生日期码，三位数字顺序码和一位数字校验码
以下是通过身份证号码获取到一个人的籍贯、生日、年龄、性别：
<script type="text/javascript"> //给身份证文本框添加一个失去焦点事件： $("#idNumber").blur(function() { //获取身份证号码，例如：412702199301010000，这里不再判断身份证号是否合法 var idNumber = $("#idNumber").val(); //定义籍贯、出生日期、性别、年龄等变量 var provinces,province,birthday,currDate,month,date,age,sex; //一、获取籍贯，由于数据量比较大，所以这里只获取到省： //定义地区数组 provinces = { 11: "北京", 12: "天津", 13: "河北", 14: "山西", 15: "内蒙古", 21: "辽宁", 22: "吉林", 23: "黑龙江", 31: "上海", 32: "江苏", 33: "浙江", 34: "安徽", 35: "福建", 36: "江西", 37: "山东", 41: "河南", 42: "湖北", 43: "湖南", 44: "广东", 45: "广西", 46: "海南", 50: "重庆", 51: "四川", 52: "贵州", 53: "云南", 54: "西藏", 61: "陕西", 62: "甘肃", 63: "青海", 64: "宁夏", 65: "新疆", 71: "台湾", 81: "香港", 82: "澳门", 91: "国外" }; province = provinces[parseInt(idNumber.substr(0, 2))]; //二、出生日期 birthday = idNumber.substring(6, 10) + "-" + idNumber.substring(10, 12) + "-" + idNumber.substring(12, 14); //三、计算年龄 currDate = new Date(); month = currDate.getMonth() + 1; date = currDate.getDate(); age = currDate.getFullYear() - idNumber.substring(6, 10) - 1; //判断年龄 if (idNumber.substring(10, 12) < month || (idNumber.substring(10, 12) == month && idNumber.substring(12, 14) <= date)) { age++; } //四、获取性别 if (parseInt(idNumber.substr(16, 1)) % 2 == 1) { //男 sex = "man"; } else { //女 sex = "woman"; } //赋值 $("#province").val(province); $("#birthday").val(birthday); $("#age").val(age); $("input[name='sex'][type=radio][value='" + sex + "']").attr("checked", true); }); </script>
