I need an example of how to validate an identification number in the Cuban identification card format. I'm looking for the regex validation in html5.
The format description:
Date of Birth (yymmdd) and 5 digits There are 11 total digits. Example: 89103024100
Note: this is uses rough date validation via pure RegEx (ie. any month can have up to 31 days):
[0-9]{2}(?:0[0-9]|1[0-2])(?:0[1-9]|[12][0-9]|3[01])[0-9]{5} You can test if a string matches via JavaScript like so:
/[0-9]{2}(?:0[0-9]|1[0-2])(?:0[1-9]|[12][0-9]|3[01])[0-9]{5}/.test('82061512345'); // returns true because it is valid If you need true date validation I would do something like the following:
var id1 = '82061512345'; // example valid id var id2 = '82063212345'; // example invalid id function is_valid_date(string) { var y = id.substr(0,2); // 82 (year) var m = id.substr(2,2); // 06 (month) var d = id.substr(4,2); // 15/32 (day) if (isNaN(Date.parse(y + '-' + m + '-' + d)) { return false; } else { return true; } } is_valid_date(id1); // returns true is_valid_date(id2); // returns false And you can tack on the following for full id validation:
function is_valid_id(id) { if (/[0-9]{11}/.test(id) && is_valid_date(id)) { return true; } else { return false; } } is_valid_id(id1); // returns true is_valid_id(id2); // returns false /(\d{2}((0[1-9]|1[012])(0[1-9]|1\d|2[0-8])|(0[13456789]|1[012]) (29|30)|(0[13578]|1[02])31)|([02468][048]|[13579][26])0229)[0-9]{5}/.test('00023012345'); return false //is not a leap year
/(\d{2}((0[1-9]|1[012])(0[1-9]|1\d|2[0-8])|(0[13456789]|1[012]) (29|30)|(0[13578]|1[02])31)|([02468][048]|[13579][26])0229)[0-9]{5}/.test('00022912345'); return true //a leap year
