使用javascript获取区域设置短日期格式

lel*_*lol 66 javascript datetime

反正我们可以使用JavaScript控制面板中使用的短日期格式 - >区域和语言设置吗？

我知道使用以下组合我们可以获得Locale Long Name格式

toString()
toLocaleString()
toLocaleDateString()
toLocaleTimeString()

但是在JavaScript中没有直接的功能toLocaleShortDateString().

是否有任何脚本可以找出用户设置是什么？

谢谢.

我在尝试弄清楚如何显示日期选择器字段的占位符时偶然发现了这个线程。最终，我希望看到基于浏览器区域设置的用户友好格式字符串（例如，'en-AU'我想显示'dd/mm/yyyy'）。

多年来，似乎有多种方法可以实现这一目标。new Intl.DateTimeFormat("en-AU")).resolved.pattern看起来它曾经得到了相当好的支持，但现在已被删除以支持formatToParts.

使用formatToParts将日期分成其组成部分可以让我们推断出模式字符串 - 这是我编写的一个基本函数来做到这一点：

/**
 * Get the date format pattern for the given locale. 
 * @example 
 *     getDateFormatPattern('en-AU');   // dd/mm/yyyy
 *     getDateFormatPattern('en-US');   // m/d/yyyy
 */
const getDateFormatPattern = (locale: string) => {
    const getPatternForPart = (part: Intl.DateTimeFormatPart) => {
        switch (part.type) {
            case 'day':
                return 'd'.repeat(part.value.length);
            case 'month':
                return 'm'.repeat(part.value.length);
            case 'year':
                return 'y'.repeat(part.value.length);
            case 'literal':
                return part.value;
            default:
                console.log('Unsupported date part', part);
                return '';
        }
    };

    return new Intl.DateTimeFormat(locale).formatToParts(new Date('2021-01-01'))
        .map(getPatternForPart)
        .join('');

无法做到.

跨浏览器JavaScript无法使用用户在提供此类区域自定义的平台上选择的实际短日期格式.此外,JavaScript存在巨大的漏洞,其中涉及任何类型的格式.看看零填充是多么麻烦!

您可以不遗余力地获取语言设置,并获得该语言环境的典型格式.当你甚至不知道它是否是正确的语言环境时(我打赌国际语言标题通常不正确或不够具体),或者如果用户已将格式定制为其他内容,那么这是很多工作.

您可以尝试使用客户端VBScript(它具有所有这些区域格式排列的功能),但这不是一个好主意,因为它是一种垂死的(死的？)特定于IE的技术.

您还可以尝试使用Java/Flash/Silverlight来挖掘格式.这也是一项额外的工作,但可能是获得成功的最佳机会.您希望为会话缓存它以最小化开销.

希望HTML5 <time>元素可以为i18n日期/时间显示提供一些缓解.

如果你有关于<input type="date">字段的问题,这里是获取字段的脚本value=""属性:

(new Date()).toISOString().split('T')[0]
Run Code Online (Sandbox Code Playgroud)

您可以使用Intl对象(ecma-402)来获取data-date-pattern="":

(new Intl.DateTimeFormat()).resolved.pattern // "M/d/y" for "en-US" in Google Chrome
Run Code Online (Sandbox Code Playgroud)

最后,要格式化当前l10n中的日期,data-date="":

(new Intl.DateTimeFormat()).format(new Date());

  • `(new Intl.DateTimeFormat()).resolved.pattern` 在 Google Chrome 中生成错误。`(new Intl.DateTimeFormat()).resolved` 是 `undefined`。这不是获取格式字符串的解决方案，但您可以使用`((new Intl.DateTimeFormat()).format(new Date());` 来获取格式化的日期字符串。 (2认同)

https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/DateTimeFormat

Intl.DateTimeFormat对象是对象的构造函数,用于启用语言敏感的日期和时间格式.

var date = new Date(2014, 11, 31, 12, 30, 0);

var formatter = new Intl.DateTimeFormat("ru");
console.log( formatter.format(date) ); // 31.12.2014

var formatter = new Intl.DateTimeFormat("en-US");

console.log(formatter.format(date)); // 12/31/2014

console.log(new Intl.DateTimeFormat(Intl.DateTimeFormat().resolvedOptions().locale).

我不知道如何做到这一点(你可以获得语言并尝试从中扣除语言环境).

我尝试做一些尝试做的事情(仅在具有一个语言环境的Firefox上测试).只要短日期字符串包含日期作为数字,就应该工作,所以它可能会失败,比如阿拉伯语.它可能还有其他错误,我不知道所有不同的locales特性,这只是一个概念......

function getShortDateFormat() {
    var d = new Date(1992, 0, 7);
    var s = d.toLocaleDateString();

    function formatReplacer(str) {
        var num = parseInt(str);
        switch (num % 100) {
            case 92:
                return str.replace(/.{1}/g, "Y");
            case 1:
                return str.length == 1 ? "mM" : "MM"
            case 7:
                return str.length == 1 ? "dD" : "DD"
        }
    }

    shortDateFormat = s.replace(/\d+/g, formatReplacer);
    return shortDateFormat;
}

getShortDateFormat();

输出的格式为:

  • Y:表示年份的位数
  • dD =短日(即尽可能只使用一位数)
  • DD =长日格式(即总是两位数)
  • mM/MM - 几个月相同

所以在我的浏览器中,你得到的shortDateformat是"MM/DD/YYYY".
