Get localized month name using native JS
It’s possible to do this to get the localized full month name using native javascript.
var objDate = new Date("10/11/2009"),
locale = "en-us",
month = objDate.toLocaleString(locale, { month: "long" });
But this only gets the month number for a given date. I’d simply like to get the month name corresponding to a month number. For example, if I do getMonth(2) it would return February. How can I implement getMonth using native javascript(no libraries like moment)?
You are already close:
var getMonth = function(idx) {
var objDate = new Date();
objDate.setDate(1);
objDate.setMonth(idx-1);
var locale = "en-us",
month = objDate.toLocaleString(locale, { month: "long" });
return month;
}
console.log(getMonth(1));
console.log(getMonth(12));To get all the months of a year and days of the week, loop over a set of dates and use toLocaleString with appropriate options to get the required values:
function getLocalDayNames() {
let d = new Date(2000,0,3); // Monday
let days = [];
for (let i=0; i<7; i++) {
days.push(d.toLocaleString('default',{weekday:'long'}));
d.setDate(d.getDate() + 1);
}
return days;
}
console.log(getLocalDayNames());
function getLocalMonthNames() {
let d = new Date(2000,0); // January
let months = [];
for (let i=0; i<12; i++) {
months.push(d.toLocaleString('default',{month:'long'}));
d.setMonth(i + 1);
}
return months;
}
console.log(getLocalMonthNames());The language default means toLocaleString uses the default language of the implementation that the code is running in.
