preventDefault() Metode Acara

Contoh

Mencegah tautan membuka URL:

document.getElementById("myAnchor").addEventListener("click", function(event){
  event.preventDefault()
});

Lebih banyak contoh "Coba Sendiri" di bawah ini.


Definisi dan Penggunaan

Metode preventDefault() membatalkan acara jika dapat dibatalkan, artinya tindakan default yang termasuk dalam acara tidak akan terjadi.

Misalnya, ini dapat berguna ketika:

  • Mengklik tombol "Kirim", mencegahnya mengirimkan formulir
  • Mengklik tautan, mencegah tautan mengikuti URL

Catatan: Tidak semua acara dapat dibatalkan. Gunakan properti yang dapat dibatalkan untuk mengetahui apakah suatu acara dapat dibatalkan.

Catatan: Metode preventDefault() tidak mencegah penyebaran lebih lanjut dari suatu peristiwa melalui DOM. Gunakan metode stopPropagation() untuk menangani ini.
