JavaScript-tekenreeks split()

Voorbeelden

Splits de woorden:

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

Splits de woorden en retourneer het tweede woord:

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

Splits de karakters, inclusief spaties:

const myArray = text.split("");

Gebruik de limietparameter:

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

Hieronder meer voorbeelden.


Definitie en gebruik

De split()methode splitst een string op in een array van substrings.

De split()methode retourneert de nieuwe array.

De split()methode verandert niets aan de originele string.

Als (" ") als scheidingsteken wordt gebruikt, wordt de tekenreeks tussen woorden gesplitst.


Syntaxis

string.split(separator, limit)

Parameters:

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.

Winstwaarde

Type Beschrijving
ArrayEen array met de gesplitste waarden.


Meer voorbeelden

Splits een tekenreeks in tekens en retourneer het tweede teken:

const myArray = text.split("");

Gebruik een letter als scheidingsteken:

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

Als de parameter separator wordt weggelaten, wordt een array met de oorspronkelijke tekenreeks geretourneerd:

const myArray = text.split();

Browserondersteuning

split()is een ECMAScript1 (ES1)-functie.

ES1 (JavaScript 1997) wordt volledig ondersteund in alle browsers:
