嗨，任何人都可以帮我改变从Gregorian到波斯语javascript的日期。我想在html javascript中使用它
week = new Array("يكشنبه", "دوشنبه", "سه شنبه", "چهارشنبه", "پنج شنبه", "جمعه", "شنبه")
months = new Array("فروردين", "ارديبهشت", "خرداد", "تير", "مرداد", "شهريور", "مهر", "آبان", "آذر", "دي", "بهمن", "اسفند");
today = new Date();
d = today.getDay();
day = today.getDate();
month = today.getMonth() + 1;
year = today.getYear();
year = (window.navigator.userAgent.indexOf('MSIE') > 0) ? year : 1900 + year;
if (year == 0) {
year = 2000;
}
if (year < 100) {
year += 1900;
}
y = 1;
for (i = 0; i < 3000; i += 4) {
if (year == i) {
y = 2;
}
}
for (i = 1; i < 3000; i += 4) {
if (year == i) {
y = 3;
}
}
if (y == 1) {
year -= ((month < 3) || ((month == 3) && (day < 21))) ? 622 : 621;
switch (month) {
case 1:
(day < 21) ? (month = 10, day += 10) : (month = 11, day -= 20);
break;
case 2:
(day < 20) ? (month = 11, day += 11) : (month = 12, day -= 19);
break;
case 3:
(day < 21) ? (month = 12, day += 9) : (month = 1, day -= 20);
break;
case 4:
(day < 21) ? (month = 1, day += 11) : (month = 2, day -= 20);

year -= ((month < 3) || ((month == 3) && (day < 20))) ? 622 : 621;
switch (month) {
case 1:
(day < 21) ? (month = 10, day += 10) : (month = 11, day -= 20);
break;
case 2:
(day < 20) ? (month = 11, day += 11) : (month = 12, day -= 19);

case 3:
(day < 20) ? (month = 12, day += 10) : (month = 1, day -= 19);

if (y == 3) {
year -= ((month < 3) || ((month == 3) && (day < 21))) ? 622 : 621;
switch (month) {
case 1:
(day < 20) ? (month = 10, day += 11) : (month = 11, day -= 19);

}
}
console.log(week[d] + " " + day + " " + months[month - 1] + " " + year);你也可以看一下：JalaliJSCalendar（github）
JalaliJSCalendar是一个基于Mihai Bazon的“Dynarch DHTML Calendar”的JavaScript日期选择器和日历小部件。两者之间的主要区别在于JalaliJSCalendar也支持波斯语（AKA Hijri Shamsi）日历，这是伊朗的官方日历。
它包含转换器（jalali.js）和HTML datepicker / calendar
你可以像下面的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
你可以使用jalaali-js
水是JavaScript
一些javascript函数用于将Jalaali（Jalali，Persian，Khayyami，Khorshidi，Shamsi）和Gregorian日历系统相互转换。
获取'jalali.js'from this link。
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from this link
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'1398/01/24'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;
}
