如何以指定的格式在 javascript 中获取日期：day. 月年？

Question

I am converting a UNIX timestamp to a date object. I managed to do the splitting of the returned date with split() . This is what I have:

var randomDate = new Date(1571990933 * 1000).toString().split('T');
console.log(randomDate[0]);

What I get: Wed Oct 30 2019 14:30:30 GM

What I want: 30. October 2019

How can I achieve this?

Answer 1

Create a months array mapping (index to human readable month name), then build your string using date.get methods for day month and year

const getDate = () => {
  const months = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'];
  const date = new Date(1571990933 * 1000);
  return `${date.getDay()}. ${months[date.getMonth()]} ${date.getFullYear()}`
}

如果包含像moment.js这样的库是一种选择，它会为您整理好一切：

 console.log( moment( new Date(1571990933 * 1000) ).format('D[.] MMMM YYYY') )
