代码:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
 layout="vertical"
 verticalAlign="middle"
 backgroundColor="white"
 creationComplete="init();"> <mx:Script>
 <![CDATA[
 import mx.controls.Alert;
 import mx.styles.StyleManager; private var alert:Alert;
 private var alertCSS:CSSStyleDeclaration; private function init():void {
 alertCSS = StyleManager.getStyleDeclaration("Alert");
 } private function showAlert(color:Object):void {
 alertCSS.setStyle("modalTransparencyColor", color);
 alertCSS.setStyle("themeColor", color);
 alert = Alert.show("The quick brown fox...");
 }
