Flex 数据的三种绑定方式

1、直接在控件属性里关联绑定：

??? <s:TextInput id="ti1" />
?? ?<s:TextInput id="ti2" text="{ti1.text}"/>

2、Flex标签声明绑定：

???<fx:Binding source="ti1.text" destination="ti2.text"/>

??? <s:TextInput id="ti1" />
?? ?<s:TextInput id="ti2" />

3、AS代码绑定

???<fx:Script>
?? ??? ?<![CDATA[
?? ??? ??? ?
?? ??? ??? ?[Bindable]
?? ??? ??? ?private var t:String;
?? ??? ??? ?
?? ??? ??? ?private function changeText(ti:TextInput):void {
?? ??? ??? ??? ?t = ti.text;
?? ??? ??? ?}

?? ??? ?]]>
???</fx:Script>

??? <s:TextInput id="ti1" change="changeText(ti1)"/>
?? ?<s:TextInput id="ti2" text="{t}"/>

示例：CheckBox全选与取消全选

??? <s:CheckBox label="{c1.selected==true? '取消全选':'全选'}" id="c1"/> ?? ?<s:CheckBox label="CheckBox" id="c2" selected="{c1.selected}"/> ?? ?<s:CheckBox label="CheckBox" id="c3" selected="{c1.selected}"/> ?? ?<s:CheckBox label="CheckBox" id="c4"/> ?? ?<s:CheckBox label="CheckBox" id="c5"/>
