当数字发生改变时，数字变大则呈现绿色的闪烁，变小则呈现红色闪烁。
只是把以前JavaScript对DOM的操作，改用as3写了一个共用类，不限于更改文字颜色。

以截图中的demo为例：
1: import com.tool.NotifyManager;
2: import flash.events.MouseEvent;
3: import flash.events.Event;
4:
5: btn1.buttonMode = true;
6: btn2.buttonMode = true;
7:
8: var txtNotify:NotifyManager;
9:
10: btn1.addEventListener(MouseEvent.CLICK, onClickHandler1);
11: btn2.addEventListener(MouseEvent.CLICK, onClickHandler2);
12:
13: function onClickHandler1(evt:MouseEvent):void
14: {
15: notifyHandler(0xFF0000);
16: }
17:
18: function onClickHandler2(evt:MouseEvent):void
19: {
20: notifyHandler(0x00FF00);
21: }
22:
23: function notifyHandler(color:uint):void
24: {
25: NotifyManager.clear(txtNotify);
26:
27: txtNotify = null;
28: txtNotify = NotifyManager.notify(changeTxtColorHandler, [color], null, null);
29: }
30:
31: function changeTxtColorHandler(color:uint, bool:Boolean):void
32: {
33: var tf:TextFormat = new TextFormat();
34: tf.color = bool ? color : 0x000000;
35:
36: //txt.setStyle("textFormat", tf);
37: txt.setTextFormat(tf);
38: }
