Flash / Flex / ActionScript/TextField/text event

Calling ActionScript from Hyperlinks

 

package {
  import flash.display.Sprite;
  import flash.text.TextField;
  import flash.events.*;
  
  public class Main extends Sprite {
    public function Main(  ) {
      var field:TextField = new TextField(  );
      field.htmlText = "<a href="event:http://www.wbex.ru">Website</a>";
      field.addEventListener(TextEvent.LINK, onClick);
      addChild(field);
    }
    private function onClick(event:TextEvent):void {
      trace("click");
    }    
  }
}

Listening to TextField Events

 
textInput Event
package
{
    import flash.text.TextField;
    import flash.display.Sprite;
    import flash.events.TextEvent;
    public class Main extends Sprite
    {
        private var inputText:TextField;
        private var regex:RegExp;
        private var dict:Array;
        public function Main()
        {
            dict = new Array("flash", "java", "C#", "python", "ruby", "C++");
            inputText = new TextField();
            inputText.type = "input";
            inputText.addEventListener(TextEvent.TEXT_INPUT, predictText);
            inputText.border = true;
            addChild(inputText);
        }
        private function predictText(textEvent:TextEvent):void
        {
            this.regex = new RegExp(textEvent.text, "i");
            for each(var term:String in dict)
            {
                if(regex.test(term))
                {
                    inputText.text = term.substring(textEvent.text.length);
                }
            }
        }
    }
}

Prevent Default Test

 
package {
     
     import flash.display.Sprite;
     import flash.text.TextField;
     import flash.text.TextFieldType;
     import flash.events.TextEvent;
     
     [SWF(width=550, height=400)]
     public class Main extends Sprite {
     
          public function Main() {
               var tf:TextField = new TextField();
               addChild(tf);
               
               tf.width = stage.stageWidth;
               tf.height = stage.stageWidth;
               tf.type = TextFieldType.INPUT;
               tf.wordWrap = true;
               
               tf.addEventListener(TextEvent.TEXT_INPUT, onTextFieldTextInput);
          }
          
          private function onTextFieldTextInput(event:TextEvent):void {
               var tf:TextField = event.target as TextField;
               if (tf.text.indexOf(event.text) > -1) {
                    event.preventDefault();
               }
          }
     
     }
}

Responding to User Text Entry: field.addEventListener(TextEvent.TEXT_INPUT, onTextInput);

 
package {
  import flash.display.Sprite;
  import flash.text.TextField;
  import flash.text.TextFieldType;
  import flash.events.TextEvent;
  import flash.events.TextEvent;
  public class Main extends Sprite {
    private var _field:TextField = new TextField(  );
    public function Main(  ) {
      _field.border = true;
      _field.background = true;
      _field.type = TextFieldType.INPUT;
      addChild(_field);
      _field.addEventListener(TextEvent.TEXT_INPUT, onTextInput);
    }
    
    private function onTextInput(event:TextEvent):void {
      if(event.text == "a" && _field.length == 0) {
          event.preventDefault(  );
      }
    }
  }
