使用原生 JS 获取本地化月份名称

问题描述

可以使用本机 javascript.

var objDate = new Date("10/11/2009"),
    locale = "en-us",
    month = objDate.toLocaleString(locale, { month: "long" });

但这只会获取给定日期的月份数.我只想获取与月份编号相对应的月份名称.例如，如果我执行 getMonth(2)，它将返回 February.如何使用本机 javascript 实现 getMonth(没有像 moment 这样的库)?

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)?

推荐答案

你已经很接近了:

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));
