Re: [flexcoders] Is there a way to find an object if you know the name

[Marlon Moyer]

sorry, I didn't phrase the question correctly.  I have the name of a component in a string variable (e.g. I've named a component 'name="repeater_state_{divisionRepeater.currentItem.id
}") and now I want to be able to refer to that component dynamically.  On 10/16/06, Gordon Smith <[EMAIL PROTECTED]

You simply refer to components by their
id. You don't have to "look them up" by it. For example, if you have

 

MyApp.mxml:

 

<mx:Application>

    <mx::Canvas id="c1">

        <mx:Button id="b1">

       ...

 

then in the Application's
<mx:Script> methods you can write expressions like b1.label.

 

Technically, what is happening is that the
MXML compiler autogenerates

 

var c1:Canvas;

var b1:Button;

 

as instance vars of a MyApp class which
extends Application. The methods you write in the <mx:Script> become
methods of this MyApp class, so they can acess these instance vars.

 

To access components inside components,
you simply use the dot operator.

What's
the equivalent of _javascript_'s getElementById in Flex? I've
searched the help files numerous times and can't seem to find it.

Thanks
