Object.prototype.toLocaleString()
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since juillet 2015.
La méthode toLocaleString() renvoie une chaine de caractères représentant l'objet. Cette méthode est destinée à être surchargée par les objets dérivés à des fins spécifiques pour prendre en compte les locales.
Exemple interactif
const date1 = new Date(Date.UTC(2012, 11, 20, 3, 0, 0));
console.log(date1.toLocaleString("ar-EG"));
// Expected output: "٢٠/١٢/٢٠١٢ ٤:٠٠:٠٠ ص"
const number1 = 123456.789;
console.log(number1.toLocaleString("de-DE"));
// Expected output: "123.456,789"
Syntaxe
js
obj.toLocaleString();
Valeur de retour
Une chaîne de caractères qui représente l'objet en tenant compte de la locale.
Description
La méthode toLocaleString renvoie le résultat de l'appel à la méthode toString().
