范例

使用 compare for array sort

使用 compare getter function for sorting arrays. Note that the function is bound to the collator from which it was obtained, so it can be passed directly to Array.prototype.sort() .

var a = ['Offenbach', 'Österreich', 'Odenwald'];
var collator = new Intl.Collator('de-u-co-phonebk');
a.sort(collator.compare);
console.log(a.join(', '));
// → "Odenwald, Österreich, Offenbach"
					

使用 compare getter function for finding matching strings in arrays:

var a = ['Congrès', 'congres', 'Assemblée', 'poisson'];
var collator = new Intl.Collator('fr', { usage: 'search', sensitivity: 'base' });
var s = 'congres';
var matches = a.filter(v => collator.compare(v, s) === 0);
console.log(matches.join(', '));
// → "Congrès, congres"
