[RESOLVED] Regex help matching 1:23.456

harmor

I'm trying to create a Mario Kart Wii script where users enter their time trials.
I'm trying to write a regex to match this format - 1:23.345
The following is the maximum amount of time an user can enter - 4.59.999

Here is the pattern I messed around with but never got it to work - /[0-4]:[0-5][0-9].[0-9]{3}/

You might need to "anchor" it with "^" at the beginning of the pattern and "$" at the end.

Nevermind. It was messing up because I had another field with the same name.

Is "1:2.345" a valid time, or must it be "1:02.345" ? Also, can it be "1:23.34" (or less) or must exactly 3 digits follow the decimal?

It looks like your pattern should work just fine, although I might add '^' and '$' so that the time can not contain other data.

EDIT: Oops.. both of you posted while I was typing/messing with the pattern. :o

It has to be "X:YY.ZZZ".

The regex works properly so no need to reply.

As you have it written above or with Nog's and I suggested addition? Because as it is in your first post, things such as "912323523528374:32.456" or "My kart is better than yours.4:12.345" will match the pattern.

Here is my new regex - /^{[0-4]:[0-5][0-9].[0-9]{3}$/}
Do I have the dollar sign in the correct spot?

Yup; placing it at the end of the pattern makes it match the end of the line (or string).
