Flex的 focusOut和focusIn的用法

得到焦点、失去焦点

<s:TextInput id="textInput1" text="{_task.name}" focusOut="_task.name=textInput2.text"/>
    <s:TextInput id="textInput2"/>-->
    <!--<s:layout>
        <s:VerticalLayout paddingLeft="5" paddingTop="5"/>
    </s:layout>
    <s:TextInput id="textInput1" text="{_task.name}" />
    <s:TextInput id="textInput2" text="{_task.name}" focusIn="textInput1.text='444'" />
    <s:TextInput id="textInput3" />
