Question

flex 4.6

I am wondering how to access/change an object using a var passed to a function, for example if I have the id vg1Text, using

Application.application.vg1Text.text = txt2chg+":"+id2chg;

works but

Application.application.id2chg.text = txt2chg+":"+id2chg;

fails with

ReferenceError: Error #1069: Property id2chg not found

thx Art

module

public function chgFuncB1(txt2chg, id2chg):void {
    Application.application.id2chg.text = txt2chg+":"+id2chg;
    }
public function myFunc() : void{
   chgFuncB1("New Text", "vg1Text");
   }

Main Application

<s:VGroup id="vg1">
    <s:Label id="vg1Text" text="Module loaded in Spark VGroup container:"/>  
</s:VGroup>

To make this work, you can use the array notation (hope that’s the correct name for it). In this way, the String contained in the variable id2chg can be used as a property name.

public function chgFuncB1(txt2chg:String, id2chg:String):void {
    Application.application[id2chg].text = txt2chg+":"+id2chg;
    }
