Control the format

[Daviso]

Hello.
I have an <input> into a html page. In this box, the user must introduce the
hour by hand. I want to control that the format is correct, for example:
10.35
22:50
etc... (just, one of them)
I have been looking for code to do this, but I can't find.
Anybody knows about this???
Thanks
David

You should not try to control the format as it is being constructed;
it's better to check that the field is valid before it is used. See
<URL:http://www.merlyn.demon.co.uk/js-valid.htm> and use something like
OK = /^\d\d[:\.]\d\d$/.test(S)

If those are times, maybe /^[0-2]\d[:\.][0-5]\d$/ - it's scarcely worth
bothering to rule out hours 24..29.
