How can i Convert persian digits to english digits?-CodePudding

I just want to change the shape of the numbers from Persian to English(i mean like this 1400/06/31). I mean to keep it Persian. Only the text font should be English. How can I do this?

 var today = new Date().toLocaleDateString('fa-IR');
  var field = document.querySelector('#tday');
  field.value = today;

<input type="text" name="tday" class="form-control w-100 text-center d-inline-block" id="tday">

You can use this function to convert Persian numbers to English numbers

export default function toEnglishDigits(num) {

  const id = {
    '۰': '0',
    '۱': '1',
    '۲': '2',
    '۳': '3',
    '۴': '4',
    '۵': '5',
    '۶': '6',
    '۷': '7',
    '۸': '8',
    '۹': '9',
  }
  return num ? num.toString().replace(/[^0-9.]/g, function (w) {
    return id[w] || w
  }) : null
}

and use this to convert English numbers to Persian numbers

export default function toPersianDigits (num) {
  if (num?.toString()) {
    const persianNumbers =
      '\u06F0\u06F1\u06F2\u06F3\u06F4\u06F5\u06F6\u06F7\u06F8\u06F9'
    return new String(num).replace(/[0123456789]/g, (d) => {
      return persianNumbers[d]
    })
  }
  return num
}

you can also pass strings to these functions with any format.

If you are okay with adding a package, use Persian Tools digitsFaToEn function:

var englishNumber = digitsFaToEn("۱۴۰۰/۰۶/۳۱")  // englishNumber = 1400/06/31
