moment.js: how to get short date format?

Question

My application sends an HTML file with javascript like this:

$(function () {
    moment.locale('fr');
    $('#datetimepicker9').datetimepicker({
        viewMode: 'years',
        locale: 'fr',
        format: '' /* <========= problem! */
    });
});

With moment, when I set to a locale, is there a way to get the short date format of the configuration like "'j F Y'" for fr?

I found it but it's hack-ish:

moment()['_locale']['_longDateFormat']['L']

So my code now:

$(function () {
    moment.locale('fr');
    $('#datetimepicker9').datetimepicker({
        viewMode: 'years',
        locale: 'fr',
        format: moment()['_locale']['_longDateFormat']['L']
    });
});

I dont like that, is there a clean way to get the format?

Answer 1

You can retrieve locale-specific format strings with the longDateFormat() of the current localeData():

moment.locale('fr');

var localeData = moment.localeData();
var dateFormat = localeData.longDateFormat('LL');

console.log(dateFormat); // D MMMM YYYY
