Convert time to 24 hours format in Javascript [closed]

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
}
