javascript for automatic time format

[Elsje2002]

Hello my dears, I'm looking for a script for a text box in which I enter the time. At the moment I have assigned the field a format (HH: MM), and if the user enters HH.MM he gets an alert. But I would like the field to automatically switch to my chosen format (similar to an Excel spreadsheet). So:  the user types 9.30 and in my text field appears 09:30. Is there a script for it? (Acrobat Pro DC 2018) Can someone help? Thanks in advance!

To do that you would need to create your own Keystroke, Format and possibly Validation scripts.

I thought so. Unfortunately, my javascript is not good enough to do that. I thought maybe someone knows a script, which I can then enter in the calculation ...

At the moment the user just gets this message "The entered value does not match the format of the field"- and that is not user friendly...

Set the format to "None" and see what happens.

that's not what I want - I want HH: MM to always be in the filled-in format - no matter how the user types it...

You should be aware that some users track time in decimal hours, so 9.30 might mean 9:18 (30/100 of an hour) and not 9:30.  How would you treat values like 9-30, 9 30 or 9.50?

This might not be as simple as you would like.There are some good reasons there is a different format for time from decimal numbers.
