HTML markup <input type="text" value="00:00:00" class="datepicker-time" aria-invalid="false"> does not display the leading zero in a text input with time format hh:mm:ss. Even though the value for the input is 00:00:00, the page shows 0:00:00. How can I force the leading zero to display?
As @Paulie_D said - use type='time' instead of text..
<input type="time" value="00:00" class="datepicker-time" aria-invalid="false"/>
One thing to note is that developer.mozilla.org has a lot of good info on how you can use this, both in JS and the general HTML items.
