How can I isolate and convert the local time format in JavaScript's new Date() to a 24 hour format?
Example: 2016-09-22T23:21:56.027Z just becomes 22:56 in local time.
回答1:
new Date("2000-01-01 10:30 AM").getHours() // 10
This is 24 hours:
new Date("2000-01-01 10:30 PM").getHours() // 22
If you want a more general thing:
function get_hours(time_string) {
return new Date("2000-01-01 " + time_string).getHours() // 22
}
回答2:
theDate.format("H:MM")
