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

function readInput(event:Event):void{ input = input_txt.text; trace(input); input_txt.text = "";}

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;
}
}
