如何在 JavaScript 中将公历日期更改为波斯日期
How to change Gregorian date to Persian date in JavaScript?
本文关键字：日期 JavaScript 更新时间：2023-09-26
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是波斯伊朗，
其他日期如下：
en-US ： 英语
hi-IN ： 印地语
。
您还可以将选项设置为第二个参数，例如：
let options = { year: 'numeric', month: 'long', day: 'numeric' };
let today = new Date().toLocaleDateString('fa-IR', options);
console.log(today);为了将字符转换为拉丁数字，您可以这样做（如Amir Fo所提到的）：
let today = new Date().toLocaleDateString('fa-IR-u-nu-latn');
console.log(today);波斯日期类
更新：这是我为处理波斯日期而编写的一个方便且轻量级的类：
class PersianDate extends Date {
constructor(...args) {
super(...args);
}
toLocaleDateString = () => super.toLocaleDateString('fa-IR-u-nu-latn');
getParts = () => this.toLocaleDateString().split("/")
getDay = () => super.getDay() === 6 ? 0 : super.getDay() + 1
getDate = () => this.getParts()[2];
getMonth = () => this.getParts()[1] - 1;
getYear = () => this.getParts()[0];
getMonthName = () => this.toLocaleDateString("fa-IR", { month: 'long' });
getDayName = () => this.toLocaleDateString("fa-IR", { weekday: 'long' });
}
用法：你可以在 js 中使用像Date类一样。支持其所有功能。
let date = new PersianDate();
date.getYear() // 1399
date.getMonth() // 1
date.getDate() // 23
date.getDay() // 0
date.getDayName() // شنبه
date.getMonthName() // اردیبهشت
date.getHours() // 18
date.getMinutes() // 59
date.getSeconds() // 30
date.setTime(1469854231000);
date.getYear() // 1395
date.getMonthName() // مرداد
getPersianDate = (format) => {

let today = new Date();
let d = today.getDay();
let day = today.getDate();

if(format==="d/m/y")
return `${day}/${month}/${year}`;
}
console.log(getPersianDate());
console.log(getPersianDate("y/m/d"));
console.log(getPersianDate("d/m/y"));您可以使用 jalali-moment 就像以下代码一样简单
import * as moment from 'jalali-moment';
let persianDate = moment("1989/1/24").locale('fa').format('YYYY/M/D'); // 1367/11/4
普伦克中的演示
您可以使用 jalaali-js
Jalaali JavaScript
一些用于转换 Jalaali 的 JavaScript 函数（Jalali、波斯语、 海亚米、霍尔希迪、沙姆西）和公历系统各有 其他。
此页面中没有答案工作正常，在某些情况下有效，但并不总是正确的！ 这是双向工作 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%=36524;
if(days >= 365)days++;
}
gy+=4*(parseInt((days)/1461));

你也可以看看这个： JalaliJSCalendar （github）
JalaliJSCalendar 是一个基于 JavaScript 日期选择器和日历小部件 在Mihai Bazon的"Dynarch DHTML Calendar"上。主要区别 两者之间是JalaliJSCalendar支持波斯语（又名回历） 沙姆西）日历也是，这是伊朗的官方日历。
它包含转换器（jalali.js）和HTML日期选择器/日历
从这个链接获取'jalali.js'。
如果您的数字是波斯语格式，首先您必须从此链接将它们更改为英语格式
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"۱۳۹۸/۰۱/۲۴"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;
}
您还可以
使用以下函数返回 JSON 中的所有选项。在此处阅读更多内容。
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]
to convert digits to Latin digits
.replace(/([۰-۹])/g, token => String.fromCharCode(token.charCodeAt(0) - 1728));
function PersianDate(raw_date) {
date = new Date(raw_date);
json_date = {
'weekday': {
'long': date.toLocaleDateString('fa-IR', { weekday: 'long' }),
'short': date.toLocaleDateString('fa-IR', { weekday: 'short' }),
'narrow': date.toLocaleDateString('fa-IR', { weekday: 'narrow' }),
},
'era': {
'long': date.toLocaleDateString('fa-IR', { era: 'long' }),
'short': date.toLocaleDateString('fa-IR', { era: 'short' }),
'narrow': date.toLocaleDateString('fa-IR', { era: 'narrow' }),
},
'timeZoneName': {

},

'2-digit': date.toLocaleDateString('fa-IR', { second: '2-digit' }),
}
}
return json_date;
}
date = PersianDate(new Date())
// Customize the output format
console.log(date['weekday']['narrow'] + ' ' + date['day']['2-digit'] + ' ' + date['month']['long'] + ' ' + date['year']['numeric']);
// Replatece Farsi digits with Latin ones, e.g. ۲۵ -> 25
console.log(date['day']['2-digit'].replace(/([۰-۹])/g, token => String.fromCharCode(token.charCodeAt(0) - 1728)));你可以为节点 js 安装这个 npm 包：
npm i jdate.js
或者为 javascript 和 html 导入此脚本：
<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 );

})();
</script>function convertDate(stringArg) {
const ETF = '۰۱۲۳۴۵۶۷۸۹';
const ans = g2j(...stringArg.split('/').map(elem => +elem))
.map(elem =>

.map(subElem => ETF[+subElem])
.join('')
)
.join('/');
return ans;
