使用原生 JS 获取本地化月份名称

Question

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));
