               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

    <s:VGroup horizontalCenter="0" verticalCenter="0">

       <s:Label text="输入你的名字"/>

2StringValidate

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

               xmlns:s="library://ns.adobe.com/flex/spark"

               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

    <fx:Declarations>

        <mx:StringValidator source="{username}"  property="text" minLength="3" maxLength="20"

                             trigger="{submitButton}" triggerEvent="click"

                             tooShortError="最少要有3个字符"

                            >

        </mx:StringValidator>

    </fx:Declarations>

    <s:VGroup horizontalCenter="0" verticalCenter="0">

       <s:Label text="输入你的名字"/>

        <s:TextInput id="username"/>

        <s:Button label="Submit" id="submitButton"/>

    </s:VGroup>

</s:Application>

3 NumberValidator

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

               xmlns:s="library://ns.adobe.com/flex/spark"

               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="" minHeight="">

    <fx:Declarations>

          <mx:NumberValidator source="{age}" property="text" allowNegative="false"

                               negativeError="年龄不太对昂"

                               minValue="" maxValue="" domain="int"

                               trigger="{submitButton}" triggerEvent="click"

              />

    </fx:Declarations>

<s:VGroup horizontalCenter="" verticalCenter="">

    <s:Label text="输入你的年龄"/>

    <s:TextInput id="age" />

    <s:Button label="Submit" id="submitButton"/>
