Wow, works like a charm; big thanks.
And if I want to test it against IDs with 3 characters I'm thinking that
RegExes are the way to go. Here's what I've got that isn't quite working.
var currentID:String = item.id.toString();
var pattern:RegExp = /^<currentID>/;
if ( pattern.test( activeID ) )
return true;
else
return false;
I'm thinking my pattern will test for the currentID (no matter how many
characters) at the beginning of the activeID. But it's not making any matches.
Am I that far off?
