[AS3]as3.0的双击事件全面解析(2)

mc_test1.doubleClickEnabled=true;  
mc_test1.addEventListener(MouseEvent.DOUBLE_CLICK,Test1Handler);  
function Test1Handler(e:MouseEvent):void  
{  
txt.text="test1双击";  
} 

mc_test2.doubleClickEnabled=true;  
mc_test2.mouseChildren=false;  
mc_test2.addEventListener(MouseEvent.DOUBLE_CLICK,Test2Handler);  
function Test2Handler(e:MouseEvent):void  
{  
txt.text="test2双击";  
trace(e.target.name);  
} 

果然这时候一切正常。为了再验证下是否真的发生在子项。添加以下输出信息。

mc_test1.doubleClickEnabled=true;  
mc_test1.addEventListener(MouseEvent.DOUBLE_CLICK,Test1Handler);  
function Test1Handler(e:MouseEvent):void  
{  
txt.text="test1双击";  
}  
 
mc_test2.doubleClickEnabled=true;  
mc_test2.addEventListener(MouseEvent.DOUBLE_CLICK,Test2Handler);  
mc_test2.addEventListener(MouseEvent.MOUSE_DOWN,TestDownHandler);  
mc_test2.addEventListener(MouseEvent.MOUSE_UP,TestUpHandler);  
mc_test2.addEventListener(MouseEvent.CLICK,TestClickHandler);  
function Test2Handler(e:MouseEvent):void  
{  
txt.text="test2双击";  
trace(e.target.name);  
}  
function TestDownHandler(e:MouseEvent):void  
{  
trace("按下2");  
trace(e.target.name);//instance4  
}  
function TestUpHandler(e:MouseEvent):void  
{  
trace("弹起2");  
trace(e.target.name);//instance4  
}  
function TestClickHandler(e:MouseEvent):void  
{  
trace("单击2");  
trace(e.target.name);//instance4  
} 

并没有输出mc_test2，而输出instance4，这应该就是自动命名的子项影片剪辑吧。
