Question

I’m terrible with Regular Expressions but I believe in this case I must create one.

Basically, a user needs to type a date of format: MM/DD/YYYY into a TextInput and I need to verify it.

Can anyone point me in the direction of those old Flex regular expression testers that I can no longer find, please?

Thanks!

UPDATE:

Here’s the regular expression just in case it’ll help someone:

var pattern:RegExp = /^(0[1-9]|1[012])[- \/.](0[1-9]|[12][0-9]|3[01])[- \/.](19|20)\d\d$/;

\d{2}/\d{2}/\d{4} for DD/DD/DDDD
\d\d?/\d\d?/\d{4} for D/D/DDDD and DD/DD/DDDD
