Assuming strings:
If (currentID.charAt(0) == activeID) { //if the first
character matches the activeId
return true;
}
Else {
return false;
}
If the ids are numbers then the logic will be different.

Subject: [flexcoders] Re: Sorting VBox elements based on an XML ID
I'm creating an ArrayCollection based on the XML loaded in. I iterate over
that and build the UI. I have a simple conditional that decides whether to
run one block of code and create a button or run another and create a radio
button. I think that part is fine as it is right now.
I've never worked with a Filter function before but what I'm understanding
is that I can get the ID for the button clicked without a problem. I've
tested that and it works. I just don't know how to compare that ID with all
the other IDs and return only the ones I want.
This is what I have so far for the Filter function:
private function stateFilterFunc(item:Object):Boolean {
var currentID:String = item.id; // The ID of the current item in the
DataProvider
var activeID:String = buttonID; // The ID of the button clicked on
if ( (activeID< currentID) )
return true;
else
return false;
}
So, how do I build the conditional that'll allow me to, in the case where ID
= 1, filter to show IDs that have 1, 11, 12, 13, etc...
And the IDs are 1 and 2 characters.
Thank you for your help.
Matt
