How to validate with Javascript an Input text with Hours and Minutes

Question

I have to build an HTML Form with an Input text field for Hours and Minutes.
Something like:

Name : [Foo]
Surname

Answer 1

You can use something like jQuery.maskedit

Answer 2

You can use this function to check for time format:

function validateTime (time) {
  const timeReg = /^([0-9]|0[0-9]|1[0-9]|2[0-3]):[0-5][0-9]:[0-5][0-9]$/
  return time.match(timeReg)
}

If you want to have just hour and minute please replace timeReg with this:

const timeReg = /^([0-9]|0[0-9]|1[0-9]|2[0-3]):[0-5][0-9]$/

And this one for the date format:

function validateDate (date) {
  try {
    new Date(date).toISOString()
    return true
  } catch (e) {
    return false
  }
}
