如何将DateTime字符串格式转换为其他DateTime？

Question

I have a string that is: Thu, 16 May 2019 08:45:15 GMT and I need to cast it to two strings: 16/05/2019 and 08:45:15 .

I have tryed many ways (I have seen other post of StackOverFlow) but I did not achieve that.

How could I do that?

EDIT 1:

I have tryed, for example, this code:

console.log(
  new Intl.DateTimeFormat(
    'en-US', { year: 'numeric', month: '2-digit', day: '2-digit', hour: '2-digit', minute: '2-digit', second: '2-digit' }
  ).format("Thu, 16 May 2019 08:45:15 GMT"))

The problem is all examples I see are from Date.now() (typeof Datetime) not a custom string like mine

Answer 1

You just need to convert that string

note: Since you are using GMT time, you'll want to call the .getUTC* function names

Also note that months are zero-indexed, so you'll need to add one to that.

 var d = new Date("Thu, 16 May 2019 08:45:15 GMT"); var dateStr = d.getUTCDate() + '/' + (d.getUTCMonth() + 1) + '/' + d.getUTCFullYear(); var timeStr = d.getUTCHours() + ':' + d.getUTCMinutes() + ':' + d.getUTCSeconds(); console.log(dateStr); console.log(timeStr); 

or given your example using Intl.DateTimeFormat you can just add a new Date() object in there (instead of a plain string) and you're good to go.

 var d = new Date("Thu, 16 May 2019 08:45:15 GMT"); var formatted = Intl.DateTimeFormat( 'en-US', { year: 'numeric', month: '2-digit', day: '2-digit', hour: '2-digit', minute: '2-digit', second: '2-digit' }).format(d); console.log(formatted);
