You could use regex. Since dot (.) has special meaning in regex you need to put 'escape' character before: yourString.search(/\./); Should work. HTH FTQuest

Exactly the same problem, creating email validation function and it got stuck on the period returning 0. This works perfectly!! – BestAnswer Aug 01 '14 at 05:12

search() accepts a pattern, and . just means "a single character", so it is probably returning the first single character, which would most likely be at index 0.

You could try search("\.")

I have never written in flash, but I'd try `search("\\.")`. – moinudin Jan 01 '11 at 17:31

I try with search(/[.]/) and it worked well in javascript, I think that It would work in the same mode in as3
