JavaScript sonu

Örnekler

3 yaşındayken bir döngüden çık:

let text = "";
for (let i = 0; i < 5; i++) {
  if (i === 3) break;
  text += i + "<br>";
}
let text = "";i = 0;
while (i < 5) {
  text += i + "<br>";
  i++;
  if (i === 3) break;
}

Aşağıda daha fazla örnek.


Tanım ve Kullanım

İfade breakbir anahtardan veya döngüden çıkar.

Bir anahtarda, anahtar bloğundan çıkar. Bu, anahtarın içinde daha fazla kodun yürütülmesini durdurur.

Bir döngüde, döngüden çıkar ve (varsa) döngüden sonra kodu yürütmeye devam eder.


Etiketleri Kullanma

İfade break, herhangi bir JavaScript kod bloğundan çıkmak için bir etiket referansı kullanabilir (aşağıdaki "Daha Fazla Örnek"e bakın).

Bir etiket olmadan, kesme yalnızca bir döngü veya anahtar içinde kullanılabilir.


Sözdizimi

break;

İsteğe bağlı etiket referansını kullanma:

break labelname;


Daha fazla örnek

Bir vaka doğru olduğunda bir anahtar bloğundan çıkın:

let day;
switch (new Date().getDay()) {
  case 0:
    day = "Sunday";
    break;
  case 1:
    day = "Monday";
    break;
  case 2:
    day = "Tuesday";
    break;
  case 3:
    day = "Wednesday";
    break;
  case 4:
    day = "Thursday";
    break;
  case 5:
    day = "Friday";
    break;
  case 6:
    day = "Saturday";
    break;
}

Listeden çıkmak:

let text = "";
const cars = ["BMW", "Volvo", "Saab", "Ford"];

list: {
  text += cars[0] + "<br>";
  text += cars[1] + "<br>";
  text += cars[2] + "<br>";
  break list;
  text += cars[3] + "<br>";
}

Örnek

Yuvalanmış bir döngüden çıkın:

// The first for loop is labeled "Loop1"
Loop1:
for (let i = 0; i < 3; i++) {

// The second for loop is labeled "Loop2"
Loop2:
  for (let i = 10; i < 15; i++) {
    if (i === 12) break Loop1;
  }
}
