给TextField.text复制后，htmlText属性也联动有了值；反之亦然

package {import flash.display.Sprite;import flash.text.TextField;public class ddddd extends Sprite{public function ddddd(){var tf:TextField = new TextField();//tf.text = "11";//trace(tf.htmlText);tf.htmlText = "<u><b>11</b></u>";trace(tf.text);addChild(tf);}}}
