Answer 1

看起来像德文语言环境格式，因此可以将Date.toLocaleDateString()和Date.toLocaleTimeString()与德文语言环境设置（de-DE）一起使用：

const date = new Date();

const dateString = date.toLocaleDateString('de-DE');
const timeString = date.toLocaleTimeString('de-DE');

const string = `${dateString} ${timeString}`;

console.log(string);

您可以根据需要使用momentjs库。

constructor(  ) { 
  let now = moment().format("YYYY-MM-DD HH:mm:ss");
  let now2 = moment().format("DD.MM.YYYY");
     this.format1 = now;
     this.format2 = now2;
     console.log(now);

    this.date = moment(this.format1, "YYYY-MM-DD HH:mm:ss");

  }

Answer 3

您可以使用Date对象的方法来构建日期字符串：

const now = new Date();

const formattedDate = now.getDate() + "." + ('0' + (now.getMonth()+1)).slice(-2) + "." + now.getFullYear();

const formattedDateTime = formattedDate + " " + now.getHours() + ":" + now.getMinutes() + ":" + now.getSeconds();

console.log(formattedDate); // 28.05.2019

console.log(formattedDateTime); // 28.05.2019 13:19:43

Javascript（ES6）日期为字符串格式
