在Javascript中本地化字符串

window.navigator.language // 获取当前系统的语言
window.navigator.userLanguage // 获取当前系统的区域 

console.log(window.navigator.language.toLowerCase()); // 获取当前系统的语言
console.log(window.navigator.userLanguage.toLowerCase()); // 获取当前系统的区域

var language = window.navigator.language.toLowerCase();

// 本地化字符串中的月份
var month = "month";
console.log(month + " " + getLocalizedWord(language, "month", "mony"));

function getLocalizedWord(locale, word, replacement) {
  var words = locale.toLowerCase().split(",");
  if (words.indexOf(word) >= 0) {
    return words[words.indexOf(word)].split("=")[1].replace('*',replacement);
  }
  return word;
}
