Limit the number of lines in an input textfield

I made one adjustment to the code because I was getting one scrolling extra line.

inputfield.textHeight > inputfield.height
to:

inputfield.textHeight >= inputfield.height

Expand | Embed | Plain Text

Copy this code and paste it in your HTML 
  1. var prevText:String;
  2. inputfield.addEventListener(Event.CHANGE, onUpdate);
  3.  
  4. private function onUpdate(e:Event):void {
  5.      if (inputfield.textHeight >= inputfield.height){
  6.            inputfield.text = prevText;
  7.      }else prevText= inputfield.text;
  8. }
