您好。根据上面的代码，我试图将点击的BitmapImage的id传递给handleClick函数。我这样做的最佳方式是什么？

无法处理BitmapImage的点击，您需要将其放在Group或其他可以处理它的容器中，下面的示例将适合您：

<![CDATA[   
            import mx.controls.Alert;
            private function handleClick(event:Event):void {
                var id:String = event.target.id;
                trace("id clicked: " + id);
                if(id == "1") {
                    trace("1 clicked");
                } else if(id=="2") {
                    trace("2 clicked");
                } else {
                    trace("Nothing");
                }
            }
        ]]>
    </fx:Script>

    <s:Group width="100%" height="100%" click="handleClick(event)" >
        <s:Group id="b1" >
            <s:BitmapImage />
        </s:Group>
        <s:Group id="b2" >
            <s:BitmapImage />
        </s:Group>
    </s:Group>

Answer 2

click="handleClick(event)"

...handleClick(event:Event)
{
   trace(event.target.id); // this is what you want
}

获取组内单击对象的ID
