关于flex 的几种绑定
第一种，使用{}绑定
<mx:TextInput
id=
"input"
/>
<mx:Label
text=
"{input.text}"
/>
第二种，<mx:Binding> 绑定
<mx:Application
xmlns:mx=
"http://www.adobe.com/2006/mxml"
layout=
"vertical"
>
<mx:TextInput
id=
"inputSource"
/>
<mx:Label
id=
"labelTarget"
/>
<mx:Binding
source=
"inputSource.text"
destination=
"labelTarget.text"
/>
</mx:Application>
第三种，使用 BindingUtils工具类
BindingUtils
.
bindProperty
(
target
,
"targetProperty"
,
source
,
"sourceProperty"
);
target:Object - 目标
targetProperty:目标属性，String类型
source:Object - 绑定源
sourceProperty:源属性，String类型
<mx:Application
xmlns:mx=
"http://www.adobe.com/2006/mxml"
layout=
"vertical"
>
<mx:TextInput
id=
"inputSource"
/>
<mx:Label
id=
"labelTarget"
/>
</mx:Application>
<script>
BindingUtils
.
bindProperty
(labelTarget,"text",inputSource,"text");
</script>
