flex数据绑定

 

1、方法绑定

   [Bindable(event="myFlagChanged")]
private function isEnabled():String {
if (myFlag)return 'true';
else return ‘false';

}

<mx:TextArea id="myTA" text="{isEnabled()}"/>

2、对象绑定

[Bindable]

publicvar expenses:ArrayCollection = new ArrayCollection(

[{Month:"01",Profit:2000,Expenses:1500,Amount:450}]

);

<mx:LineChart id="lineChart" dataProvider="{expenses}“>

</mx:LineChart>
