Flex学习 为一个事件建立多个监听

方法一：
<?xml version="1.0"?>
<!-- events/MultipleEventHandlersInline.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script><![CDATA[
private function submitForm(e:Event):void {
// Handle event here.
}
private function debugMessage(e:Event):void {
// Handle event here.
}
]]></mx:Script>

<mx:Button id="b1"
label="Do Both Actions"
click='submitForm(event); debugMessage(event);'

/>

</mx:Application>
方法二：
<?xml version="1.0"?>
<!-- events/MultipleEventHandlersAS.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="createHandlers(event)">
<mx:Script><![CDATA[
public function createHandlers(e:Event):void {
b1.addEventListener(MouseEvent.CLICK, submitForm);
b1.addEventListener(MouseEvent.CLICK, debugMessage);
}
private function submitForm(e:Event):void {
// Handle event here.
}
private function debugMessage(e:Event):void {
// Handle event here.
}
]]></mx:Script>
<mx:Button id="b1" label="Click Me"/>
</mx:Application>
