这里是根据 @J_A_X 中的解释示例，但它使用 default MouseEvent 您可以扩展 *MouseEvent* 类来保存您的自定义数据

Here is sample according to explanation in @J_A_X but its using default MouseEvent You can extent *MouseEvent* Class to hold your custom data

<?xml version="1.0" encoding="utf-8"?>
<mx:Application 
    xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
    click="{clicked(event)}">
    <mx:Script>
        <![CDATA[
            import mx.controls.LinkButton;
            import mx.core.UIComponent;
            import mx.controls.Alert;
            public function clicked(event:MouseEvent):void
            {
                if (event.target is LinkButton)
                {
                    var innerLinkButon:LinkButton = event.target as LinkButton;
                    Alert.show("Application : "+innerLinkButon.label);
                }
            }
        ]]>
