Append text to TextField

   <source lang="java">

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);
   }
 }

}

       </source>
   
  

Displaying Text

   <source lang="java">

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);
   }
 }

}

       </source>
   
  

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

   <source lang="java">

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);
   }
 }

}

       </source>
   
  

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

   <source lang="java">

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);
   }
 }

}

       </source>
   
  

Retrieving Strings from a TextField

   <source lang="java">

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));
      }
   }

}

       </source>
   
  

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

   <source lang="java">

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);
   }
 }

}

       </source>
   
  

The getLineIndexOfChar()/getLineLength()

   <source lang="java">

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);
       }
   }

} }

       </source>
   
  

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

   <source lang="java">

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);
   }
 }

}

       </source>
   
  

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

   <source lang="java">

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);
   }
 }

}

       </source>
