Intl.Locale.prototype.collation property is an accessor property that returns the collation type 为 Locale , which is used to order strings according to the locale's rules.

描述

Collation is the process of ordering strings of characters. It is used whenever strings must be sorted and placed into a certain order, from search query results to ordering records in a database. While the idea of placing strings in order might seem trivial, the idea of order can vary from region to region and language to language. The collation property helps to make it easier for JavaScript programmers to access the collation type used by a particular locale.

Below is a table with the available collation types, taken from the Unicode collation specification .

Valid collation types

Collation Type	描述
big5han	Pinyin ordering for Latin, big5 charset ordering for CJK characters (used in Chinese)
compat	A previous version of the ordering, for compatibility

范例

Like other locale subtags, the collation type can be added to the Intl.Locale object via the locale string, or a configuration object argument to the constructor.

Adding a collation type via the locale string

在 Unicode locale string spec , collation types are locale key "extension subtags". These subtags add additional data about the locale, and are added to locale identifiers by using the -u extension. Thus, the collation type can be added to the inital locale identifier string that is passed into the Locale constructor. To add the collation type, first add the -u extension to the string. Next, add the -co extension to indicate that you are adding a collation type. Finally, add the collation to the string.

let stringColl = new Intl.Locale("en-Latn-US-u-co-emoji");
console.log(stringColl.collation); // Prints "emoji"
					

Adding a collation type via the configuration object argument

Intl.Locale constructor has an optional configuration object argument, which can contain any of several extension types, including collation types. Set the collation property of the configuration object to your desired collation type, and then pass it into the constructor.

let configColl = new Intl.Locale("en-Latn-US", {collation: "emoji"});
console.log(configColl.collation); // Prints "emoji"
