[align=center]积少成多Flash(12) - Flex 3.0 验证控件(Validator), 缓动效果(easing) [/align]

作者：webabcd

介绍
演示 Flex 3.0 中的验证控件的应用，以及各种缓动效果(easing)的应用
Validator - 各种验证控件的基类，其可用于必填验证
DateValidator - 日期验证控件
EmailValidator - Email 验证控件
RegExpValidator - 正则表达式验证控件
缓动（easing） - 系统自带的动画缓动效果，以及自定义缓动效果
加密/解密 - 常用加密算法的 AS3 库的应用
其他 - 其他一些常用的东西

在线DEMO
