membuat program, ada kalanya kita ingin agar data yang diinput tidak
salah. Teknik Validasi yang anda terapkan pun, misalnya validasi nama
tidak boleh angka terkadang tidak maksimal. Kalau misalnya kita salah
mengetik nama “Ivan” dengan “Ivam”, pasti nama akan lansung tersimpan
bukan? Bukan hanya itu, biasanya seorang user tidak sengaja menekan
tombol “enter”. Padahal belum selesai mengetik. Ada cara untuk
mengatasi hal diatas, yakni dengan membuat pertanyaan konfirmasi.
Pertanyaan konfirmasi berfungsi untuk menampilkan pertanyaan “ok” dan
“cancel”. Ini untuk memastikan apakah data yang diinput sudah benar
dengan melakukan pengecekan ulang.
style="text-align: justify; text-indent: 0.5in; line-height:
normal;">Pertanyaan konfirmasi
sepeti diatas dapat dibuat dengan javascript.
pertanyaan.js lalu ketikkan script berikut :
pertanyaan.js
normal;">lang="IN">function pertanyaan()
color: rgb(0, 112, 192);" lang="IN">{

kode diatas :
Pada
pertanyaan.js, dibuatkan perintah confirm untuk menampilkan kotak pesan
ok dan cancel. Karena menggunakan function, kita gunakan return TRUE
jika benar dan return FALSE jika salah. Lalu pada bagian yang ingin
dimunculkan pertanyaan, tambahkan perintah onclick. Maksudnya ketika
diklik,event apa yang terjadi.
