My challenge involves an input field with a value (model) in microseconds (e.g. 1950), and a filter that converts the microseconds into a human-readable format such as 00:19.50 (which is displayed in the input field). How can I ensure or enforce that the user maintains this format?
To achieve this, you can utilize the pattern attribute which accepts a regular expression.
For more information, you can refer to this link:
Here is an example they provide:
<input type="url" name="website" required pattern="https?://.+">
I trust that this information is beneficial to you.
@gapvision has offered you an answer with a suitable pattern for your requirements
pattern='\d\d:\d\d.\d\d'
To set a specific time format, you can use the pattern='\d\d:\d\d:\d\d':
<input type="text" pattern="\d\d:\d\d:\d\d" required>
