jquery通过身份证号获取性别和生日

项目中有遇到需要根据用户输入的身份证号码自动获取出身日期及性别。在网上搜了一些方法在项目中使用。现整理记录一下，方便后面使用。

card.js代码，用于判断身份证号格式是否正确（主要是长度和出身日期）：

//判断身份证格式function isIdCardNo(num) {var factorArr = new Array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2, 1);var parityBit = new Array("1", "0", "X", "9", "8", "7", "6", "5", "4", "3", "2");var varArray = new Array();var lngProduct = 0;var intCheckDigit;var intStrLen = num.length;var idNumber = num;// initializeif ((intStrLen != 15) && (intStrLen != 18)) {return false;}// check and set valuefor (var i = 0; i < intStrLen; i++) {varArray[i] = idNumber.charAt(i);if ((varArray[i] < '0' || varArray[i] > '9') && (i != 17)) {return false;} else if (i < 17) {varArray[i] = varArray[i] * factorArr[i];}}//判断18位长度if (intStrLen == 18) {//check datevar date8 = idNumber.substring(6, 14);if (isDate8(date8) == false) {return false;}// calculate the sum of the productsfor (var i = 0; i < 17; i++) {lngProduct = lngProduct + varArray[i];}// calculate the check digitintCheckDigit = parityBit[lngProduct % 11];// check last digitif (varArray[17] != intCheckDigit) {return false;}//判断18位长度}else {//check datevar date6 = idNumber.substring(6, 12);if (isDate6(date6) == false) {return false;}}return true;}//15位长度判断生日function isDate6(sDate) {if (!/^[0-9]{6}$/.test(sDate)) {return false;}var year, month, day;year = sDate.substring(0, 4);month = sDate.substring(4, 6);if (year < 1700 || year > 2500) return false;if (month < 1 || month > 12) return false;return true;}//18位长度判断生日function isDate8(sDate) {if (!/^[0-9]{8}$/.test(sDate)) {return false;}var year, month, day;year = sDate.substring(0, 4);month = sDate.substring(4, 6);day = sDate.substring(6, 8);var iaMonthDays = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]if (year < 1700 || year > 2500) return false;if (((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0)) iaMonthDays[1] = 29;if (month < 1 || month > 12) return false;if (day < 1 || day > iaMonthDays[month - 1]) return false;return true;}

js中的根据日期获取生日和性别的方法：

function getSexAndbirthday (IdCard) {var birthday = "";var sexNo = "";var sex = "";if(IdCard.length === 15) {birthday = '19'+IdCard.substr(6,2)+'-'+IdCard.substr(8,2)+'-'+IdCard.substr(10,2);sexNo = IdCard.substring(14,15)} else if (IdCard.length === 18) {birthday = IdCard.substr(6,4)+'-'+IdCard.substr(10,2)+'-'+IdCard.substr(12,2);sexNo = IdCard.substring(16,17)}if (sexNo%2==0){sex = 'FEMALE';}else {sex = 'MALE';}return {sex: sex, birthday: birthday};}
