从身份证号码中获取相关信息，比如生日，省：
function checkID(ID) {
if(typeof ID !== ‘string‘) return ‘非法字符串‘;
var city = {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"};
var birthday = ID.substr(6, 4) + ‘/‘ + Number(ID.substr(10, 2)) + ‘/‘ + Number(ID.substr(12, 2));
var d = new Date(birthday);
var newBirthday = d.getFullYear() + ‘/‘ + Number(d.getMonth() + 1) + ‘/‘ + Number(d.getDate());
var currentTime = new Date().getTime();
var time = d.getTime();
var arrInt = [7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2];
var arrCh = [‘1‘, ‘0‘, ‘X‘, ‘9‘, ‘8‘, ‘7‘, ‘6‘, ‘5‘, ‘4‘, ‘3‘, ‘2‘];
var sum = 0, i, residue;
if(!/^\d{17}(\d|x)$/i.test(ID)) return ‘非法身份证‘;
if(city[ID.substr(0,2)] === undefined) return "非法地区";
if(time >= currentTime || birthday !== newBirthday) return ‘非法生日‘;
for(i=0; i<17; i++) {
sum += ID.substr(i, 1) * arrInt[i];
}
residue = arrCh[sum % 11];
if (residue !== ID.substr(17, 1)) return ‘非法身份证哦‘;
return city[ID.substr(0,2)]+","+birthday+","+(ID.substr(16,1)%2?" 男":"女")
}
验证香港身份证的格式或真实性：
function IsHKID(str) {
var strValidChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
// basic check length
if (str.length < 8)
return false;
// handling bracket
if (str.charAt(str.length-3) == ‘(‘ && str.charAt(str.length-1) == ‘)‘)
str = str.substring(0, str.length - 3) + str.charAt(str.length -2);
// convert to upper case
str = str.toUpperCase();
// regular expression to check pattern and split
var hkidPat = /^([A-Z]{1,2})([0-9]{6})([A0-9])$/;
var matchArray = str.match(hkidPat);
// not match, return false
if (matchArray == null)
return false;
// the character part, numeric part and check digit part
var charPart = matchArray[1];
var numPart = matchArray[2];
var checkDigit = matchArray[3];
// calculate the checksum for character part
var checkSum = 0;
if (charPart.length == 2) {
checkSum += 9 * (10 + strValidChars.indexOf(charPart.charAt(0)));
checkSum += 8 * (10 + strValidChars.indexOf(charPart.charAt(1)));
} else {
checkSum += 9 * 36;
checkSum += 8 * (10 + strValidChars.indexOf(charPart));
}
// calculate the checksum for numeric part
for (var i = 0, j = 7; i < numPart.length; i++, j--)
checkSum += j * numPart.charAt(i);
// verify the check digit
var remaining = checkSum % 11;
var verify = remaining == 0 ? 0 : 11 - remaining;
return verify == checkDigit || (verify == 10 && checkDigit == ‘A‘);
}
在网上找了很久都没合意的验证方式，最后通过Google找到一个国外写的js验证，发现可以使用。
上面那段验证的很精密，包含身份证真实性的校验，如果只是想验证输入的香港身份证格式，请使用下面的这段js。
function IsHKID(str) {
var strValidChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
// basic check length
if (str.length < 8)
return false;
// handling bracket
if (str.charAt(str.length-3) == ‘(‘ && str.charAt(str.length-1) == ‘)‘)
str = str.substring(0, str.length - 3) + str.charAt(str.length -2);
// convert to upper case
str = str.toUpperCase();
// regular expression to check pattern and split
var hkidPat = /^([A-Z]{1,2})([0-9]{6})([A0-9])$/;
var matchArray = str.match(hkidPat);
// not match, return false
if (matchArray == null)
return false;
return true;
}
