You can also easily generate any numbers using the Luhn algorithm: useDragonCode\CardNumber\CardNumber; CardNumber::generate(1);// 18CardNumber::generate(2);// 26CardNumber::generate(10);// 109CardNumber::generate(90);// 901CardNumber::generate(908);// 9084 ...
// takes the form field value and returns true on valid number function valid_credit_card(value) { // accept only digits, dashes or spaces if (/[^0-9-\s]+/.test(value)) return false; // The Luhn Algorithm. It's so pretty. var nCheck = 0, nDigit = 0, bEven = false; value...
