Đây là code dịch ngược viết bằng java, em dùng ChatGPT để convert về js giúp anh với nhé, nếu không được thì anh sẽ convert về js giúp em sau:

public class VietQRDecoder {

    private static final String PREFIX = "000201010212";
    private static final String SUFFIX = "6304";
    private static final String PART_11_PREFIX = "0010A00000072701";
    private static final String PART_2_PREFIX = "530370454";
    private static final String PART_21_PREFIX = "5802VN62";
    private static final int CHECK_SUM_LENGTH = 4;

    public static void main(String[] args) {
        Map<String, String> information = new HashMap<>();
        String input = "00020101021238540010A00000072701240006970436011010137721710208QRIBFTTA530370454061000005802VN62090805Hello63049F12";
        String parts = input.substring(
            PREFIX.length(),
            input.length() - SUFFIX.length() - CHECK_SUM_LENGTH
        );
        parts = parts.substring(2);
        int part1Length = Integer.parseInt(parts.substring(0, 2));
        parts = parts.substring(2);
        String part1 = parts.substring(0, part1Length);

        part1 = part1.substring(PART_11_PREFIX.length());
        int part12Length = Integer.parseInt(part1.substring(0, 2));
        part1 = part1.substring(2);
        String part12 = part1.substring(0, part12Length);

        part12 = part12.substring(2);
        int bankIdLength = Integer.parseInt(part12.substring(0, 2));
        part12 = part12.substring(2);
        String bankId = part12.substring(0, bankIdLength);
        information.put("bankId", bankId);

        part12 = part12.substring(bankIdLength);
        part12 = part12.substring(2);
        int bankAccountLength = Integer.parseInt(part12.substring(0, 2));
        part12 = part12.substring(2);
        String bankAccount = part12.substring(0, bankAccountLength);
        information.put("bankAccount", bankAccount);

        parts = parts.substring(part1Length);
        String part2 = parts.substring(PART_2_PREFIX.length());
        int amountLength = Integer.parseInt(part2.substring(0, 2));
        part2 = part2.substring(2);
        String amount = part2.substring(0, amountLength);
        information.put("amount", amount);

        part2 = part2.substring(amountLength);
        part2 = part2.substring(PART_21_PREFIX.length());
        int part21Length = Integer.parseInt(part2.substring(0, 2));
        part2 = part2.substring(2);
        String part21 = part2.substring(0, part21Length);

Em sẽ cần if else các trường hợp không có dữ liệu ở các trường số tiền, message, ví dụ:

public class VietQRDecoderV2 {

    private static final String SUFFIX = "6304";

    private static final String AMOUNT_HEADER = "54";
    private static final String PART_21_PREFIX = "5802VN62";
    private static final int CHECK_SUM_LENGTH = 4;

    public static void main(String[] args) {

        String parts = input.substring(
            PREFIX.length(),
            input.length() - SUFFIX.length() - CHECK_SUM_LENGTH
        );
        parts = parts.substring(2);
        int part1Length = Integer.parseInt(parts.substring(0, 2));
        parts = parts.substring(2);
        String part1 = parts.substring(0, part1Length);

        part1 = part1.substring(PART_11_PREFIX.length());

        part12 = part12.substring(2);
        int bankIdLength = Integer.parseInt(part12.substring(0, 2));
        part12 = part12.substring(2);
        String bankId = part12.substring(0, bankIdLength);

        String bankAccount = part12.substring(0, bankAccountLength);
        information.put("bankAccount", bankAccount);

        parts = parts.substring(part1Length);
        String part2 = parts.substring(PART_2_PREFIX.length());
        if (part2.startsWith(AMOUNT_HEADER)) {
            part2 = part2.substring(2);
            int amountLength = Integer.parseInt(part2.substring(0, 2));
            part2 = part2.substring(2);
            String amount = part2.substring(0, amountLength);
