Merhabalar,
Bu yazıda input text alanına alınan değerlerin bir buton yardımıyla güncellenerek outputtext komutuyla xhtml sayfasında gösteriminin bir örneğini uyguladım. Aynı zamanda update komutunun da birden fazla id’yi boşluk bırakarak güncellediğini yine örneğimizin xhtml sayfasında görebileceğiz. Görsel olarak detaylara takılmadan komutların nasıl çalıştıklarını örnek üzerinden göstermeye çalışıyorum.
