将PHP代码转换为Javascript以将数字读入句子

Question

I want to convert my PHP code to JavaScript. The code's purpose is for read numbers into sentence. The problem is the sentence won't showing into input text. Here is the code:

JavaScript

function pembilang(angka) {
    var bilangan =[
            '',
            'SATU',
            'DUA',
            'TIGA',
            'EMPAT',
            'LIMA',
            'ENAM',
            'TUJUH',
            'DELAPAN',
            'SEMBILAN',
            'SEPULUH',
            'SEBELAS'
    ];

    if (angka < 12) {
        $('#NILAI_HURUF').val(bilangan[angka]);
    } else if (angka < 20) {
        $('#NILAI_HURUF').val(bilangan[angka - 10] + ' BELAS');
    } else if (angka < 100) {
        hasil_bagi == (angka / 10);
        hasil_mod == angka % 10;
        $('#NILAI_HURUF').val(trim(sprintf('%s PULUH %s', bilangan[hasil_bagi], bilangan[hasil_mod])));
    } else if (angka < 200) {
        $('#NILAI_HURUF').val('SERATUS %s', terbilang(angka - 100));
    } else if (angka < 1000) {
        hasil_bagi == (angka / 100);
        hasil_mod == angka % 100;
        $('#NILAI_HURUF').val(trim(sprintf('%s RATUS %s', $bilangan[hasil_bagi], terbilang(hasil_mod))));
    } else if (angka < 2000) {
        $('#NILAI_HURUF').val(trim(sprintf('SERIBU %s', terbilang(angka - 1000))));
    } else if (angka < 1000000) {
        hasil_bagi == (angka / 1000);
        hasil_mod == angka % 1000;
        $('#NILAI_HURUF').val(sprintf('%s RIBU %s', terbilang(hasil_bagi), terbilang(hasil_mod)));
    } else if (angka < 1000000000) {
        hasil_bagi == (angka / 1000000);
        hasil_mod == angka % 1000000;
        $('#NILAI_HURUF').val(trim(sprintf('%s JUTA %s', terbilang(hasil_bagi), terbilang(hasil_mod))));
    } else if (angka < 1000000000000) {
        hasil_bagi == (angka / 1000000000);
        hasil_mod == fmod(angka, 1000000000);
        $('#NILAI_HURUF').val(trim(sprintf('%s MILYAR %s', terbilang(hasil_bagi), terbilang(hasil_mod))));
    } else if (angka < 1000000000000000) {
        hasil_bagi == angka / 1000000000000;
        hasil_mod == fmod(angka, 1000000000000);
        $('#NILAI_HURUF').val(trim(sprintf('%s TRILIYUN %s', terbilang(hasil_bagi), terbilang(hasil_mod))));
    } else {
        alert('Too many digits.');
    }
}

Then this is where I input the numbers:

html

<input onkeypress="return isNumberKey(event);" onChange="pembilang(this.value);" class="form-control" placeholder="Masukan nilai angka..." name="NILAI_ANGKA_AKHIR" type="number" required>

And this is where the sentence must be displayed:

html

<input id="NILAI_HURUF" value="" class="form-control disabled" placeholder="Masukan no induk..." name="NILAI_HURUF" type="text" required>

Answer 1

Okay, I solved it by myself.

I just give a variable like this into JavaScript function :

angka = angka;

The solution is implementing/add JavaScript module from phpjs.org/functions/sprintf. Then the code for displaying that sentences is like this:

JavaScript

function pembilang(angka) {
    var angka = angka;

    var bilangan =[
            '',
            'SATU',
            'DUA',
            'TIGA',
            'EMPAT',
            'LIMA',
            'ENAM',
            'TUJUH',
            'DELAPAN',
            'SEMBILAN',
            'SEPULUH',
            'SEBELAS'
    ];

    if (angka < 12) {
        $('#NILAI_HURUF').val(bilangan[angka]);
    } else if (angka < 20) {
        $('#NILAI_HURUF').val(bilangan[angka - 10] + ' BELAS');
    } else if (angka < 100) {
        hasil_bagi = Math.floor(angka / 10);
        hasil_mod = angka % 10;
        //   example 4: sprintf("%s", 123456789012345);
        var x = sprintf("%s PULUH %s", bilangan[hasil_bagi], bilangan[hasil_mod]);
        $('#NILAI_HURUF').val(x);
    } else if (angka < 101) {
        var x = sprintf("SERATUS %s", bilangan[angka - 100]);
        $('#NILAI_HURUF').val(x);
    }else {
        alert('Maksimal nilai 100.');
    }
}
