JavaScript stringa split()

Esempi

Dividi le parole:

let text = "How are you doing today?";
const myArray = text.split(" ");

Dividi le parole e restituisci la seconda parola:

let text = "How are you doing today?";
const myArray = text.split(" ");
let word = myArray[1];

Dividi i caratteri, inclusi gli spazi:

const myArray = text.split("");

Usa il parametro limite:

const myArray = text.split(" ", 3);

Altri esempi di seguito.


Definizione e utilizzo

Il split()metodo divide una stringa in una matrice di sottostringhe.

Il split()metodo restituisce il nuovo array.

Il split()metodo non modifica la stringa originale.

Se (" ") viene utilizzato come separatore, la stringa viene suddivisa tra parole.


Sintassi

string.split(separator, limit)

Parametri

Parameter Description
separator Optional.
A string or regular expression to use for splitting.
If omitted, an array with the original string is returned.
limit Optional.
An integer that limits the number of splits.
Items after the limit are excluded.

Valore di ritorno

Tipo Descrizione
VettoreUna matrice contenente i valori divisi.


Altri esempi

Dividi una stringa in caratteri e restituisce il secondo carattere:

const myArray = text.split("");

Usa una lettera come separatore:

const myArray = text.split("o");

Se il parametro separator viene omesso, viene restituita una matrice con la stringa originale:

const myArray = text.split();
