Append text to TextField

 
package {
  import flash.display.Sprite;
  import flash.text.TextField;
  public class Main extends Sprite {
    public function Main(  ) {
      var field:TextField = new TextField(  );
    field.autoSize = flash.text.TextFieldAutoSize.LEFT;
    field.text = "A";
    field.text += "\n";
    field.text += "B."; addChild(field);
    }
  }
}

Displaying Text

 
package {
  import flash.display.Sprite;
  import flash.text.TextField;
  public class Main extends Sprite {
    public function Main(  ) {
      var field:TextField = new TextField(  );
      field.type = flash.text.TextFieldType.INPUT;
      field.border = true;
      field.background = true; 
      field.text = "this will display in the field";
      addChild(field);
    }
  }
}

If beginIndex and endIndex are equal, the newText is inserted immediately before the specified beginIndex

 
package{
  import flash.display.Sprite;
  import flash.text.*;
  public class Main extends Sprite{
    public function Main(){
        var t:TextField = new TextField(  );
        t.text = "mat";
        t.replaceText(2, 2, "s");
        trace(t.text);  // Displays: mast
        addChild(t);
    }
  }
}

Replaces the characters "bcd" in the text "abcde" with the new text "x"

 

package{
  import flash.display.Sprite;
  import flash.text.*;
  public class Main extends Sprite{
    public function Main(){
        var t:TextField = new TextField(  );
        t.text = "abcde";
        t.replaceText(1, 4, "x");
        trace(t.text);  // Displays: axe
        addChild(t);
    }
  }
}

Retrieving Strings from a TextField

 
package {
    import flash.text.TextField;
    import flash.events.MouseEvent;
    import flash.display.Sprite;
    
    public class WidthHeightTest extends Sprite
    {
       private var txt:TextField;
       public function WidthHeightTest()
       {
    
             txt = new TextField();
             txt.autoSize = "left";
             addChild(txt);
             txt.text = "conductor.";
             txt.addEventListener(MouseEvent.MOUSE_MOVE, getTextUnderMouse);
       }
    
       private function getTextUnderMouse(mouseEvent:MouseEvent):void
       {
             var charInt:int = txt.getCharIndexAtPoint(mouseEvent.stageX, mouseEvent.stageY);
             trace(txt.text.charAt(charInt));
       }
    }
}

Special characters, such as \t for tab and \n for newline, can be used within a text string.

 
package {
  import flash.display.Sprite;
  import flash.text.TextField;
  public class Main extends Sprite {
    public function Main(  ) {
      var field:TextField = new TextField(  );
 
      field.text = "this will \n display in the field";
      addChild(field);
    }
  }
}

The getLineIndexOfChar()/getLineLength()

 
package
{
import flash.display.Sprite;
import flash.text.TextField;
import flash.text.TextFormat;
import flash.events.TextEvent;
public class Main extends Sprite
{
    private var input:TextField;
    private var text:TextField;
    private var regex:RegExp;
    private var selectedFormat:TextFormat;
    private var defaultFormat:TextFormat;
    public function Main()
    {
        defaultFormat = new TextFormat();
        defaultFormat.bold = false;
        defaultFormat.color = 0x00000;
        selectedFormat = new TextFormat();
        selectedFormat.color = 0xFF0000;
        selectedFormat.bold = true;
        input = new TextField();
        input.type = "input";
        input.border = true;
        input.height = 20;
        addChild(input);
        input.addEventListener(TextEvent.TEXT_INPUT, checkInput);
        text = new TextField();
        text.text = "development.";
        text.wordWrap = true;
        text.multiline = true;
        addChild(text);
        text.y = 200;
    }
    private function checkInput(textEvent:TextEvent):void
    {
        text.setTextFormat(defaultFormat);
        var indexOfInt:int;
        var lineIndex:int;
        var firstChar:int;
        var lastChar:int;
        if((indexOfInt = text.text.indexOf(input.text)) != -1)
        {
            lineIndex = text.getLineIndexOfChar(indexOfInt);
            firstChar = text.getLineOffset(lineIndex);
            lastChar = firstChar + text.getLineLength(lineIndex);
            text.setTextFormat(selectedFormat, firstChar, lastChar);
        }
    }
}
}

The url property allows you to add a hyperlink to text.

 

package{
  import flash.display.Sprite;
  import flash.text.*;  
  public class Main extends Sprite{
    public function Main(){
        var tContent:TextField = new TextField();
        tContent.multiline = true;
        
        tContent.border = true;
        tContent.wordWrap = true;
        tContent.text = "Visit the Web site";
        var tfFormatter:TextFormat = new TextFormat();
        tfFormatter.url = "http://thefactoryfactoryfactory.ru/wordpress";
        tfFormatter.target = "_blank";
        tfFormatter.underline = true;
        tContent.setTextFormat(tfFormatter,2,5);
        addChild(tContent);
    }
  }
}

You can append text by using the += operator or the appendText( ) method

 
package {
  import flash.display.Sprite;
  import flash.text.TextField;
  public class Main extends Sprite {
    public function Main(  ) {
      var field:TextField = new TextField(  );
     field.appendText("new text");
     addChild(field);
    }
  }
}
