Question

I have a date sting in the format as below: 2017-05-25T08:00:00.0000000+00:00

How to Extract the time in hh:ss format from the ISO format?

Answer 1

由于严格定义了ISO8601，因此只需一个简单的substr就可以了

 console.log('2017-05-25T08:00:00.0000000+00:00'.substr(11,8)); 

Answer 2

You can use a regular expression with .match() method:

 var date = "2017-05-25T08:00:00.0000000+00:00"; console.log(date.match(/(\\d+:\\d+:\\d+)+/)[0])
