句法

new Intl.Collator([locales[, options]])
					

参数

locales

Optional. A string with a BCP 47 language tag, or an array of such strings. For the general form and interpretation of the locales argument, see the Intl page . The following Unicode extension keys are allowed:

co

Variant collations for certain locales. Possible values include: "big5han" , "dict" , "direct" , "ducet" , "gb2312" , "phonebk" , "phonetic" , "pinyin" , "reformed" , "searchjl" , "stroke" , "trad" , "unihan" 。 "standard" and "search" values are ignored; they are replaced by the options property usage (see below).

kn

Whether numeric collation should be used, such that "1" < "2" < "10". Possible values are "true" and "false" . This option can be set through an options property or through a Unicode extension key; if both are provided, the options property takes precedence.

kf

Whether upper case or lower case should sort first. Possible values are "upper" , "lower" ，或 "false" (use the locale's default). This option can be set through an options property or through a Unicode extension key; if both are provided, the options property takes precedence.

options

Optional. An object with some or all of the following properties:

localeMatcher

The locale matching algorithm to use. Possible values are "lookup" and "best fit" ; the default is "best fit" . For information about this option, see the Intl page .

usage

Whether the comparison is for sorting or for searching for matching strings. Possible values are "sort" and "search" ; the default is "sort" .

sensitivity

Which differences in the strings should lead to non-zero result values. Possible values are:

• "base" : Only strings that differ in base letters compare as unequal. Examples: a ≠ b , a = á , a = A .
• "accent" : Only strings that differ in base letters or accents and other diacritic marks compare as unequal. Examples: a ≠ b , a ≠ á , a = A .
• "case" : Only strings that differ in base letters or case compare as unequal. Examples: a ≠ b , a = á , a ≠ A .
• "variant" : Strings that differ in base letters, accents and other diacritic marks, or case compare as unequal. Other differences may also be taken into consideration. Examples: a ≠ b , a ≠ á , a ≠ A .

默认为 "variant" for usage "sort" ; it's locale dependent for usage "search" .

ignorePunctuation

Whether punctuation should be ignored. Possible values are true and false ; the default is false .

numeric

Whether numeric collation should be used, such that "1" < "2" < "10". Possible values are true and false ; the default is false . This option can be set through an options property or through a Unicode extension key; if both are provided, the options property takes precedence. Implementations are not required to support this property.

caseFirst

Whether upper case or lower case should sort first. Possible values are "upper" , "lower" ，或 "false" (use the locale's default); the default is "false" . This option can be set through an options property or through a Unicode extension key; if both are provided, the options property takes precedence. Implementations are not required to support this property.

范例

使用 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.
