在moment.js中本地化日期和月份 [英] Localizing day and month in moment.js

问题描述

如何在moment.js中本地化当前日期和月份(无年份)?我想要的只是moment().format('LL')的输出，但没有年份部分.

How can I localize current day and month (without year) in moment.js? What I want is exactly the output of moment().format('LL') but without the year part.

请考虑以下示例:

moment().locale('tr').format('LL') // "1 Haziran 2017"
moment().locale('en').format('LL') // "June 1, 2017"

我想要的是这些

moment().locale('tr').format('??') // "1 Haziran"
moment().locale('en').format('??') // "June 1"

推荐答案

对于所有受支持的语言环境的易于出错的解决方案，您需要使用.replace删除year并检查是否留有不必要的符号:

For error prone solution for all supported locales, you need to remove year with .replace and check for unnecessary symbols left:

function getCurrDayAndMonth(locale) {
  var today = locale.format('LL');
  return today
    .replace(locale.format('YYYY'), '') // remove year
    .replace(/\s\s+/g, ' ')// remove double spaces, if any
    .trim() // remove spaces from the start and the end
    .replace(/[рг]\./, '') // remove year letter from RU/UK locales
    .replace(/de$/, '') // remove year prefix from PT
    .replace(/b\.$/, '') // remove year prefix from SE
    .trim() // remove spaces from the start and the end
    .replace(/,$/g, ''); // remove comma from the end
}
