使用鼠标事件操作获取 flex 组件 ID

Question

在flex应用程序中如何使用鼠标事件获取特定显示组件的ID。例如，如果我想获得一个按钮的 ID，当我点击按钮时应该显示它

Answer 1

用 event.currentTarget.id 这样做：

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

    <fx:Script>
        <![CDATA[
            import mx.controls.Alert;
            protected function niceButton_clickHandler(event:MouseEvent):void
            {
                Alert.show(" the button id is: "+event.currentTarget.id)

            }
        ]]>
    </fx:Script>

    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>
    <s:HGroup width="100%" height="100%" verticalAlign="middle" horizontalAlign="center">
        <s:Button id="niceButton" label="click me" click="niceButton_clickHandler(event)" />
    </s:HGroup>
</s:Application>
