Get 'jalali.js' from this link.

If your numbers is in Persian format, at first you have to change them to English format, 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;
        };

and use such as the function 'getGregorian()' below to convert date. For instance I convert '۱۳۹۸/۰۱/۲۴' date:

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;

        }
