Javascript 如何使用非英语字符串创建日期

Question

var date = new Date ("Mai 15, 2018 10:41:48"); 

该字符串是德语。正如预期的那样，我收到错误“无效日期”，因为 JS 希望我输入英文。

我不想使用toLocaleString()，因为我正在尝试从不同的语言初始化日期。

您可以使用moment.js https://momentjs.com/docs/#/i18n/

let localLocale = moment();

localLocale.locale('de'); // set this instance to use German
let date = localLocale.date("Mai 15, 2018 10:41:48").toDate();
console.log(date);

// if you don't want to add this dependency, you can do something like this 


let str = 'Mai 15, 2018 10:41:48';
const months = {
  Januar: 'January',
  Februar: 'February',
  'März': 'Macrh',
  Marz: 'March',
  April: 'April',
  Mai: 'May',
  Juni: 'June',
  Juli: 'July',
  August: 'August',
  September: 'September',
  Oktober: 'October',
  November: 'November',
  Dezember: 'December'
};

let month = str.split(' ')[0];
console.log(new Date(str.replace(month, months[month])));

// I am leaving timezone handling to you. Put some effort
