Flex 内置验证器—验证用户输入
今晚对于Flex中的Validator类（所有验证器的父类）测试一下
----》其中常用的验证类有StringValidator，NumberValidator，DateValidator 测试如下：
1 <?xml version="1.0" encoding="utf-8"?> 2 <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 3 xmlns:s="library://ns.adobe.com/flex/spark" 4 xmlns:mx="library://ns.adobe.com/flex/mx" 5 width="867" height="530" minWidth="955" minHeight="600"> 6 7 <fx:Script> 8 <![CDATA[ 9 import mx.controls.Alert; 10 protected function click(event:MouseEvent):void 11 { 12 Alert.show("你的姓名:"+test1.text+"\n你的年龄:"+test2.text+"\n你的生日:"+test3.text); 13 } 14 ]]> 15 </fx:Script> 16 <fx:Declarations> 17 <!-- 将非可视元素（例如服务、值对象）放在此处 --> 18 <mx:StringValidator source="{test1}" property="text" minLength="3" maxLength="20" 19 trigger="{test_btn}" triggerEvent="click" 20 tooShortError="字符数不能少于3！" tooLongError="字符数不能多于20！" /> 21 <s:NumberValidator source="{test2}" property="text" allowNegative="false" 22 negativeError="不允许为负数" trigger="{test_btn}" triggerEvent="click" 23 domain="int"/> 24 <mx:DateValidator source="{test3}" property="text" inputFormat="yyyy/mm/dd" 25 allowedFormatChars="/" trigger="{test_btn}" triggerEvent="click"/> 26 </fx:Declarations> 27 <s:VGroup width="381" height="215" horizontalCenter="0" verticalCenter="0"> 28 <s:Label width="289" height="25" fontSize="20" text="Enter your name:"/> 29 <s:TextInput id="test1" /> 30 <s:Label width="289" height="25" fontSize="20" text="Enter your age:"/> 31 <s:TextInput id="test2"/> 32 <s:Label width="289" height="25" fontSize="20" text="Enter your birth date:"/> 33 <s:TextInput id="test3"/> 34 <s:Button id="test_btn" width="109" height="25" label="提交" click="click(event)"/> 35 </s:VGroup> 36 </s:Application>
此外还有EmailValida、CreditValidator、CurrencyValidator、PhoneNumberValidator等都是常用的内置验证器~
