setStyle to Variable's id

Question

I want to apply a font style to the objectSelect that hold id. I know currentTarget.id or Target.id do the job but any way to make the setStyle apply to "text1"?

private function changeFontStyleFromCombobox(e:Event):void {
    trace(objectSelect); //it hold "text1" value from one of the textarea.id
    if(objectSelect != null) { // shown text1
    objectSelect.setStyle("fontFamily", e.target.selectedLabel);
    }
}

e.target.selectedLabel value come from combobox.
