Script ini untuk membuat background halaman situs dengan tampilan seperti layaknya di angkasa luar pada malam hari.
Terlihat cahaya/bintang beterbangan dengan cepat.
Scriptnya adalah ;
1. Menambambahkan TAG onLoad="fly()" pada <BODY>
<BODY onLoad="fly()">
1. Memasukan Java Script di antara TAG <BODY></BODY>

Cek Kode Warna 2
Script ini untuk melakukan pengecekan kode warna dengan script yang lebih simple.
Bisa juga dipakai sebagai pengganti background color oleh pengunjung halaman situs.
Langkahnya adalah sebagai berikut;
1. Masukan kode js di antara <HEAD></HEAD>
<SCRIPT LANGUAGE="JavaScript">
function color(form) {
if (form.text.value == "")
alert("Cek Kode Warna")
else {
document.bgColor=(""+form.text.value+"");
}
}
</SCRIPT>
2. Buat Form dengan input box, diantara tag <BODY></BODY>
<form name=Interface>
<input type="text" name="text">
<input type="button" name="button" value="Cek Warna" onClick="color(this.form)">
</form>

Java Script Untuk Yang Lagi Belajar
Secara ringkas saja, java script itu adalah bahasa script yang biasanya di pakai di halaman-halaman situs yang fungsinya untuk memperbagus situs atau menambahkan menu-menu yang dinamis.
Langkah dalam penggunaan Java Script adalah dengan menyisipkan script tersebut pada tag html sebuah halaman.
Biasanya di awali dengan <SCRIPT LANGUAGE="JavaScript">
ISI SCRIPT DI SINI
Dan di akhiri </SCRIPT>
Dan penempatan script tersebut terdapat di antara TAG <HEAD></HEAD>
dan atau <BODY></BODY>
Atau Bisa juga menyimpan script tersebut menjadi sebuah file berekstensi .js (dot js).
Dan penyisipannya dengan cara merujukan file js tersebut diantara TAG <BODY></BODY>
Misal : <BODY><SCRIPT LANGUAGE="JavaScript" src="URL FILE.JS></SCRIPT></BODY>
