ActionScript 3: get the first character from the first element of an array

Question

I am learning AS3 (coming from a PHP background) and I have hit a wall.

Basically I have this code:

var activeNotesNames:Array; activeNotesNames = new Array; activeNotesNames.push("ABC");

and doing a

trace(activeNotesNames[0])

gives me "ABC" but if I just want the first character (in this case that would be "A") how do I get that?

I tried trace(activeNotesNames[0][0] but that gives me an error.

The problem with [0][0] is that the String "ABC" is not an array. As Pan pointed out, you need to use a method of the String class to access individual characters. That syntax would work if instead of having a String you had another array in there. — Pier

3

activeNotesNames[0].charAt(0);

Or you can try substr

Thank you! Can you tell me which is an easy place to look up methods like this? Compared to php.net finding this stuff for AS3 is quite hard... but I think I am looking in the wrong places. (I have to wait 9 mins to accept your answer)

You can find the api in adobe livedoc, it helps a lot when you are not familiar with the api. help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/…
