Evaluating a variable that contains a variable

[cheftimo]

Hello, all:

I have a bindable variable that contains the name of another variable that I
want to return. Example:

[Bindable]
var price:String = "dollars";
[Bindable]
var dollars: Number = "10.00"

If I use {price} in some expression, the output is 'dollars'. I am looking for
a way to use {price} and have it output '10.00'. How would I do this in AS 3?

This would be like the ColdFusion function 'Evaluate()', where
#Evaluate(price)#, which would return '10.00'.

Any ideas would be highly appreciated. Thanks,

Carlos

I thought this might work, but it does not:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[
[Bindable]
private var price:String = String(dollars);
[Bindable]
private var dollars: Number = 10.00;

private function clickHandler():void{
dollars = 20.00;
}
]]>
</mx:Script>

<mx:Button label="Click Me" click="clickHandler()"/>
<mx:TextArea id="txtArea" width="300" height="200" text="{price}"/>
</mx:Application>

You can do it like so.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[

[Bindable]
private var price:String;
private var currencyString:String = "dollars";
private var dollars: Number = 10.00;

private function clickHandler():void{
price = this[currencyString];
}
]]>
</mx:Script>

<mx:Button label="Click Me" click="clickHandler()"/>
<mx:TextArea id="txtArea" width="300" height="200" text="{price}"/>
