I am trying to create a regular expression for matching dates. After finding
that my regex pattern didn't work I decided to pare it down and see if I
could figure out why. Now I can't get the test to just match a single
character and reject multiple characters.

So in my test I have myRegex.pattern = "[0-9]" and myRegex.test("15"), if I
am not mistaken that regular expression should just match 1 digit right? But
15 returns true because it finds at least 1 of the digits that matches.

Am I doing something wrong? thanks.

I would think that you'd get two matches, the 1 and the 5. Perhaps it was
the way you were accessing the matches that returned the full number. But
since you didn't post any code....

icccapital was thinking very hard :

Cool... Also, you can drop the quantifier :) I don't know why I put
that in. Rusty, I guess :)

^/d$
