var textInput:TextInput = new TextInput();
textInput.x = 100;
textInput.y = 10;
addChild(textInput);

var t:Timer = new Timer(100);
t.addEventListener(TimerEvent.TIMER, caretindex);

function caretindex(e:TimerEvent):void {
	var caretIndex:Number = textfield.getCharIndexAtPoint(textfield.mouseX, textfield.mouseY)
	if(caretIndex == -1) {
		return;
	}
	var str:String = textfield.text;
	var words:Array = str.split(' ');
	var n:Number = 0;
	while(n<=words.length){
		var subset:Array = words.slice(0, n);

Get Even or Odd – getParity using Action Script AS

The below code shows how to use the class


import druva.NumberUtil;

trace('500', NumberUtil.getParity(500));
// true

    public function NumberUtil(){
    }

    public static function getParity(num:Number):String {
		return (num % 2) ? 'odd' : 'even';
