JavaScript RegExp i Modifier


Lakukan pencarian case-insensitive untuk "is":

let text = "Visit W3Schools";
let pattern = /w3schools/i;
let result = text.match(pattern);

Definisi dan Penggunaan

Pengubah "i" menentukan kecocokan case-insenitive.

Dukungan Peramban

/regexp/iadalah fitur ECMAScript1 (ES1).

ES1 (JavaScript 1997) didukung penuh di semua browser:

Chrome IE Edge Firefox Safari Opera
Yes Yes Yes Yes Yes Yes

Sintaksis

new RegExp("regexp", "i")

or simply:

/regexp/i

Lebih Banyak Contoh

Lakukan pencarian case-insensitive untuk "w3schools" dalam sebuah string:

Menggunakan fungsi RegExp exec()::

let text = "Visit W3Schools";
let pattern = /w3schools/i;
let result = pattern.exec(text);

Menggunakan tes fungsi RegExp()::

let text = "Visit W3Schools";
let pattern = /w3schools/i;
let result = pattern.test(text);

Menggunakan fungsi String match():

let text = "Visit W3Schools";
let pattern = /w3schools/i;
let result = text.match(pattern);


Tip

Anda dapat menggunakan properti abaikanCase untuk memeriksa apakah pengubah "i" telah disetel.

Contoh

let pattern = /W3S/i;
let result = pattern.ignoreCase;

Metode Pencarian Ekspresi Reguler

Dalam JavaScript, pencarian teks ekspresi reguler, dapat dilakukan dengan metode yang berbeda.

Dengan pola sebagai ekspresi reguler, ini adalah metode yang paling umum:

ContohKeterangan
text.match( pola )Metode String cocok()
teks.pencarian ( pola )Pencarian metode String()
pola .exec(teks)Metode RexExp exec()
pola .test(teks)Tes metode RegExp()
