谁能帮我在 JavaScript 中将公历日期更改为波斯语？我想在 HTML 和 JavaScript 中使用它。

您可以使用toLocaleDateString();

let today = new Date().toLocaleDateString('fa-IR');
console.log(today);

fa-IR是波斯语-伊朗，

其他日期如下：

en-US: 英语

hi-IN: 对于印地语

...

您也可以将选项设置为第二个参数，例如：

let options = { year: 'numeric', month: 'long', day: 'numeric' };
new Date().toLocaleDateString('fa-IR', options);

为了将字符转换为拉丁数字，您可以执行以下操作：


let today = new Date().toLocaleDateString('fa-IR');
today.replace(/([۰-۹])/g, token => String.fromCharCode(token.charCodeAt(0) - 1728));

要获得波斯数字：

new Date().toLocaleDateString('fa-IR');
// ۱۳۹۹/۱/۲۳

要获得拉丁数字：

new Date().toLocaleDateString('fa-IR').replace(/([۰-۹])/g, token => String.fromCharCode(token.charCodeAt(0) - 1728));
// 1399/1/23

您可以像以下代码一样简单地使用jalali-moment

import * as moment from 'jalali-moment';
let persianDate = moment("1989/1/24").locale('fa').format('YYYY/M/D'); // 1367/11/4

您可以使用jalaali-js

贾拉里 JavaScript

一些用于将 Jalaali（Jalali、Persian、Khayyami、Khorshidi、Shamsi）和公历系统相互转换的 javascript 函数。

你也可以看看这个：JalaliJSCalendar ( github )

JalaliJSCalendar 是一个 JavaScript 日期选择器和日历小部件，基于 Mihai Bazon 的“Dynarch DHTML 日历”。两者的主要区别在于 JalaliJSCalendar 也支持波斯（AKA Hijri Shamsi）日历，这是伊朗官方日历。

它包含转换器 ( jalali.js ) 和 HTML datepicker/calendar

此页面中的答案都不是正确的，它在某些情况下有效，但并不总是正确的！这适用于两种转换方法：

function gregorian_to_jalali(gy,gm,gd){
        var g_d_m=[0,31,59,90,120,151,181,212,243,273,304,334];
        var jy=(gy<=1600)?0:979;
        gy-=(gy<=1600)?621:1600;
        var gy2=(gm>2)?(gy+1):gy;
        var days=(365*gy) +(parseInt((gy2+3)/4)) -(parseInt((gy2+99)/100))
                +(parseInt((gy2+399)/400)) -80 +gd +g_d_m[gm-1];
        jy+=33*(parseInt(days/12053));
        days%=12053;
        jy+=4*(parseInt(days/1461));
        days%=1461;
        jy+=parseInt((days-1)/365);
        if(days > 365)days=(days-1)%365;
        var jm=(days < 186)?1+parseInt(days/31):7+parseInt((days-186)/30);
        var jd=1+((days < 186)?(days%31):((days-186)%30));
        return [jy,jm,jd];
    }
function jalali_to_gregorian(jy,jm,jd){
        var gy=(jy<=979)?621:1600;
        jy-=(jy<=979)?0:979;
        var days=(365*jy) +((parseInt(jy/33))*8) +(parseInt(((jy%33)+3)/4))
                +78 +jd +((jm<7)?(jm-1)*31:((jm-7)*30)+186);
        gy+=400*(parseInt(days/146097));
        days%=146097;
        if(days > 36524){
            gy+=100*(parseInt(--days/36524));

        days%=1461;
        gy+=parseInt((days-1)/365);
        if(days > 365)days=(days-1)%365;
        var gd=days+1;

从此链接获取“jalali.js” 。

如果您的数字是波斯语格式，首先您必须将它们更改为英文格式，从此链接

var
        persianNumbers = [/۰/g, /۱/g, /۲/g, /۳/g, /۴/g, /۵/g, /۶/g, /۷/g, /۸/g, /۹/g],
        arabicNumbers = [/٠/g, /١/g, /٢/g, /٣/g, /٤/g, /٥/g, /٦/g, /٧/g, /٨/g, /٩/g],
        fixNumbers = function (str) {
            if (typeof str === 'string') {
                for (var i = 0; i < 10; i++) {
                    str = str.replace(persianNumbers[i], i).replace(arabicNumbers[i], i);
                }
            }
         return str;
        };

并使用下面的函数“getGregorian()”来转换日期。例如，我转换 '13۹۸/01/24' 日期：

function getGregorian () {
            var date = ("۱۳۹۸/۰۱/۲۴").split('/');
            y = Number( fixNumbers(date[0]) );
            m = Number( fixNumbers(date[1]) );
            d = Number( fixNumbers(date[2] ));

            gDate = toGregorian(y, m, d)
            gDate = gDate .gy + '/' + gDate .gm + '/' + gDate .gd;

        }

你可以为 node js 安装这个 npm 包：

npm i jdate.js

或者为 javascript 和 html 导入这个脚本：

<script src="https://cdn.jsdelivr.net/npm/jdate.js"></script>

用法：

var date = new Date();
console.log( date.echoFa() );
console.log( date.echo() );
console.log( date );

您还可以使用以下函数返回 JSON 中的所有选项。在这里阅读更多。

options:
    weekday      -> [long | short | narrow]
    era          -> [long | short | narrow]
    timeZoneName -> [long | short]

    year         -> [numeric | 2-digit]
    month        -> [numeric | 2-digit | long | short | narrow]
    day          -> [numeric | 2-digit]
    hour         -> [numeric | 2-digit]
    minute       -> [numeric | 2-digit]
    second       -> [numeric | 2-digit]
