javascript - display day and month, without a year according to locale

Question

Is there any better way for getting only day and month from a date including location appropriate separator?

I have a solution that gets separator first:

 function getDateSep() {
   var temp = moment().format('L');
   var locale = moment().locale;
   var datesep = temp.substring(5, 6);
   return datesep;
}

and then builds the date like this:

var sep = function getDateSep()
var date = date.format('D' + sep + 'M'+ sep)

Is there a solution that builds the whole date dynamically?

The result I want to achieve would be like: 31.01 (dd.mm) 31/01 (dd/mm) 01.31 (mm.dd) 01/31 (mm/dd) etc

Answer 1

Have you considered using Date#toLocaleDateString instead of monentjs?

It takes a JS Date object and options to output a locale date in the format you specify.

Example:

var date = new Date();
var options = { day: 'numeric', month: 'short' };

console.log(date.toLocaleDateString('en-GB', options));
// outputs: Feb 24

var numeric = { day: 'numeric', month: 'numeric' };

console.log(date.toLocaleDateString('en-GB', numeric));
// outputs: 24/02

As pointed out in the comments, it's worth ensuring that your targeted platforms support the toLocaleDateString approach above with options. For instance, this approach isn't currently supported by Android webview as detailed here for toLocaleDateString's Browser_compatibility
