Clearing the TextArea texts when I press Enter key

Question

How to clear the texts that I have typed into the TextArea when I press Enter Key?
I have now added a TextArea instance called input_txt to the stage and added an component event listener to detect when I press enter key. Then an event fires up which first reads the input to a string variable.
But next I need to automatically clear the texts in the TextArea.
How to do that?
function readInput(event:Event):void
    input = input_txt.text;
    trace(input);
    // removing texts in the text input area-------- how?
input_txt.addEventListener(ComponentEvent.ENTER, readInput);
Please help.
Thank You

ComponentEvent.ENTER occurs before the line feed is added to the text, and is not cancelable, so you'll probably need to set a flag and do the clearing in an Event.CHANGE handler. Something like this:
import fl.events.ComponentEvent;
input_text.addEventListener(ComponentEvent.ENTER, readInput);
input_text.addEventListener(Event.CHANGE, changeHandler);
var clearing:Boolean=false;
function readInput(event:Event):void
    input = input_txt.text;
    trace(input);
    clearing=true;
function changeHandler(event:Event)
if(clearing)
  input_text.text="";
  clearing=false;
