Re: [flexcoders] Re: Dynamically creating item IDs
Believe you need to pass the event object:
mx:TextInput preinitialize=assignID(event)/
But, that's a pretty good idea!

RE: [flexcoders] Re: Dynamically creating item IDs
Are you talking about the id=... attribute on MXML tags? All it does it autogenerate a public var in the class. For example, if you write mx:Button id=b/ in an MXML component then the autogenerated AS class has the instance var public var b:Button; So if you plan on dynamically instantiating components instead of statically declaring them with tags, you simply declare your own var as above and then do b = new Button(); The difference between this approach and AJAX is that AS3 gets its performance gain over Javascript by having non-dynamic classes (where all properties and methods are declared at compilation time) in addition to to dynamic ones. Flex components are mostly non-dynamic for speed. So you simply declare variables to be the id's of the components you're going to create later. - Gordon From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of thetexaspsycho2003 Sent: Thursday, March 01, 2007 1:12 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Dynamically creating item IDs --- In flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com , thetexaspsycho2003 [EMAIL PROTECTED] wrote: Is there a way to dynamically create an item's ID?

Re: [flexcoders] Re: Dynamically creating item IDs
I'm not mr. actionscript but a class like this should facilitate what
you need.
class Idgen {
static var nextid:int = 0 ;
static function getNext:String() {
return id + nextid;
nextid++;
}
static function reset:void() {
nextid = 0;
}
}
Then call Idgen.getNext() to get a series of unique ids.

Re: [flexcoders] Re: Dynamically creating item IDs
You can also check out Flex's NameUtil class (mx.utils.NameUtil I believe).
It basically does what Jason suggested but tracks a separate series of id's
per class name. Thus, you get get series such as Button1, Button2, Button3,
HList1, HList2, etc.
If you're talking about globally unique ID (or universally unique ID),
there's a function somewhere in the API (search IUUID or UUID in the docs)
that'll do a best attempt at generating an ID in AS based on the random
number generator and the clock (which is the practically the best you can do
without the Flash Player being able to provide something like a NIC serial
number or CPU ID).
