您好可以任何人帮我改变从Gregorian到波斯语javascript的日期。我想在html javascript中使用它
答案 0 :(得分：12)
您可以使用：toLocaleDateString（）;
例如：
let today = new Date().toLocaleDateString('fa-IR');
console.log(today);
fa-IR适用于波斯语和波斯语， 别人就像在吼叫：
“ zh-CN”：对于英语
“ hi-IN”：对于印地语
。

以波斯数字获取它：
new Date().toLocaleDateString('fa-IR');
// ۱۳۹۹/۱/۲۳
要获取其拉丁数字：
new Date().toLocaleDateString('fa-IR').replace(/([۰-۹])/g, token => String.fromCharCode(token.charCodeAt(0) - 1728));
// 1399/1/23

获取'jalali.js'from this link。
如果您的电话号码是波斯格式，则首先必须将其更改为英语格式，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，我将“ ۱۳۹۸/۰۱/۲۴”日期转换为：
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;
}
