Flex学习--为一个事件建立多个监听

 

<?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>
