How to format default date in javascript?

Question

I'm trying to format an string date that looks like this:

Tue Mar 13 2018 00:00:00 GMT-0600 (Mountain Daylight Time)}

to:

"2018-03-13T00:00:00",

Can anyone tell me what I'm missing or need to add? Thanks a lot in advance!

 let someDate = 'Tue Mar 13 2018 00:00:00 GMT-0600 (Mountain Daylight Time)}'; console.log(someDate.replace(/T.+$/, "T00:00:00")); 

Answer 1

 let someDate = 'Tue Mar 13 2018 00:00:00 GMT-0600 (Mountain Daylight Time)'; console.log(new Date(someDate).toISOString().replace(/T.+$/, "T00:00:00")); 

Answer 2

someDate.toISOString（）将为您提供ISO格式的日期
