HTML input time in 24 format
As stated in this answer not all browsers support the standard way. It is not a good idea to use for robust user experience. And if you use it, you cannot ask too much.
Instead use time-picker libraries. For example: TimePicker.js is a zero dependency and lightweight library. Use it like:
var timepicker = new TimePicker('time', {
lang: 'en',
theme: 'dark'
});
timepicker.on('change', function(evt) {
var value = (evt.hour || '00') + ':' + (evt.minute || '00');
evt.element.value = value;
});<script src="https://cdn.jsdelivr.net/timepicker.js/latest/timepicker.min.js"></script>
<link href="https://cdn.jsdelivr.net/timepicker.js/latest/timepicker.min.css" rel="stylesheet"/>
<div>
<input type="text" id="time" placeholder="Time">
</div>More info about the time input can be found on MDN Web Docs
<!DOCTYPE html>
<html>
<body>
Time: <input type="time" id="myTime" value="16:32:55">
<p>Click the button to get the time of the time field.</p>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction() {
var x = document.getElementById("myTime").value;
document.getElementById("demo").innerHTML = x;
}
</script>
</body>
</html>I found that by setting value field (not just what is given below) time input will be internally converted into the 24hr format.
You can't do it with the HTML5 input type. There are many libs available to do it, you can use momentjs or some other jQuery UI components for the best outcome.
