Intl.Collator()
Collator
对象。
Intl.Collator.supportedLocalesOf()
Returns an array containing those of the provided locales that are supported without having to fall back to the runtime's default locale.
Intl.Collator.prototype.compare
Intl.Collator
对象。
Intl.Collator.prototype.resolvedOptions()
Returns a new object with properties reflecting the locale and collation options computed during initialization of the object.
Collator
The following example demonstrates the different potential results for a string occurring before, after, or at the same level as another:
console.log(new Intl.Collator().compare('a', 'c')); // → a negative value
console.log(new Intl.Collator().compare('c', 'a')); // → a positive value
console.log(new Intl.Collator().compare('a', 'a')); // → 0
Note that the results shown in the code above can vary between browsers and browser versions. This is because the values are implementation-specific. That is, the specification requires only that the before and after values are negative and positive.
locales
The results provided by
Collator.prototype.compare()
vary between languages. In order to get the sort order of the language used in the user interface of your application, make sure to specify that language (and possibly some fallback languages) using the
locales
argument:
// in German, ä sorts with a
console.log(new Intl.Collator('de').compare('ä', 'z'));
// → a negative value
// in Swedish, ä sorts after z
console.log(new Intl.Collator('sv').compare('ä', 'z'));
// → a positive value
options
The results provided by
Collator.prototype.compare()
can be customized using the
options
argument:
// in German, ä has a as the base letter
console.log(new Intl.Collator('de', { sensitivity: 'base' }).compare('ä', 'a'));
// → 0
// in Swedish, ä and a are separate base letters
console.log(new Intl.Collator('sv', { sensitivity: 'base' }).compare('ä', 'a'));
// → a positive value
