JavaScript Dize değiştir()

Örnekler

Microsoft'u değiştirin:

let text = "Visit Microsoft!";
let result = text.replace("Microsoft", "W3Schools");

Küresel bir değiştirme:

let text = "Mr Blue has a blue house and a blue car";
let result = text.replace(/blue/g, "red");

Aşağıda daha fazla örnek.


Tanım ve Kullanım

Yöntem replace(), bir değer veya normal ifade için bir dize arar.

Yöntem replace(), değiştirilen değer(ler)le yeni bir dize döndürür.

Yöntem replace(), orijinal dizeyi değiştirmez.


Not

Bir değeri değiştirirseniz, yalnızca ilk örnek değiştirilir. Tüm örnekleri değiştirmek için g değiştirici seti ile normal bir ifade kullanın.

Düzenli ifadeler hakkında daha fazla bilgiyi şuramızda okuyun:


Sözdizimi

Daha fazla örnek

Küresel, büyük/küçük harfe duyarsız bir değiştirme:

let text = "Mr Blue has a blue house and a blue car";
let result = text.replace(/blue/gi, "red");

Değiştirilen metni döndürme işlevi:

let text = "Mr Blue has a blue house and a blue car";
let result = text.replace(/blue|house|car/gi, function (x) {
  return x.toUpperCase();
});
