描述

Object 's toLocaleString returns the result of calling toString() .

This function is provided to give objects a generic toLocaleString method, even though not all may use it. See the list below.

Objects overriding toLocaleString

• Array : Array.prototype.toLocaleString()
• Number : Number.prototype.toLocaleString()
• Date : Date.prototype.toLocaleString()
• TypedArray : TypedArray.prototype.toLocaleString()
• BigInt : BigInt.prototype.toLocaleString()

范例

Array toLocaleString() override

On Array objects, toLocaleString() can be used to print array values as a string, optionally with locale-specific identifiers (such as currency symbols) appended to them:

例如：

const testArray = [4, 7, 10];
let euroPrices = testArray.toLocaleString('fr', { style: 'currency', currency: 'EUR'});
// "4,00 €,7,00 €,10,00 €"
					

Date toLocaleString() override

On Date objects, toLocaleString() is used to print out date displays more suitable for specific locales:

例如：

const testDate = new Date(Date.now());
// "Date Fri May 29 2020 18:04:24 GMT+0100 (British Summer Time)"
let deDate = testDate.toLocaleString('de');
// "29.5.2020, 18:04:24"
var frDate = testDate.toLocaleString('fr');
//"29/05/2020 à 18:04:24"
					

Number toLocaleString() override

On Number objects, toLocaleString() is used to print out number displays more suitable for specific locales, e.g. with the correct separators:

例如：

const testNumber = 2901234564;
// "2901234564"
let deNumber = testNumber.toLocaleString('de');
// "2.901.234.564"
let frNumber = testNumber.toLocaleString('fr');
// "2 901 234 564"
