Customize numeric values in Moment Arabic localization

问题

I want to create my own locale in moment.js, its parent should be the Arabic local but I want only to change to numeric format to display 0-9, not the default display.

As per documentation, I can start with that:

moment.defineLocale('ar-sa-mine', {
  parentLocale: 'ar-sa',
  /*
     here I need to specify the numeric: change **this ٢٩ to 29**
  */
});

If you look at locale/ar-sa.js code you will note that moment uses preparse and postformat to convert from numeric characters to arabic.

You can simply restore default behaviour resetting preparse and postformat (e.g. see moment code: function preParsePostFormat (string) { return string; })

Here a live sample:

console.log( moment().format() );
console.log( moment().format('dddd DD MMMM YYYY') );

moment.defineLocale('ar-sa-mine', {
  parentLocale: 'ar-sa',
  preparse: function (string) {
    return string;
  },
  postformat: function (string) {
    return string;
  }
});

console.log( moment().format() );
console.log( moment().format('dddd DD MMMM YYYY') );
