示例

¥Examples

基本示例

¥Basic Example

const myLoc = new Intl.Locale("fr-Latn-CA"); // Sets locale to Canadian French

console.log(myLoc.baseName); // Prints out "fr-Latn-CA"

输入字符串中包含选项的示例

// Sets language to Japanese, region to Japan,

// calendar to Gregorian, hour cycle to 24 hours
const japan = new Intl.Locale("ja-JP-u-ca-gregory-hc-24");
console.log(japan.toString()); // Prints out "ja-JP-u-ca-gregory-hc-h24"
console.log(japan.baseName); // Prints out "ja-JP"

// Input string indicates language as Dutch and region as Belgium,

// but options object overrides the region and sets it to the Netherlands
