Trigger event from child to parent in AS3

问题

I have a MovieClip with a MouseEvent function associated to CLICK event. Inside of this MovieClip I have a TextField.

So, when I click on my MovieClip, the handler works fine. Now I need the same behaviour when I click on this TextField, but without change my handler function. I mean, I don't want to change e.target to e.target.parent if user clicked on TextField instead of MovieClip.

How can I do this?

Some of my source code:

public function Main(){
   var m = new menu();
   menuMng.addChild(m);
   m.addEventListener(MouseEvent.CLICK, openMenu);
}

private function openMenu(e:MouseEvent):void{
   // Do some stuff
}

Thanks in advance!

This is a fairly common question - you can use the event.currentTarget property instead of event.target to reference the object to which you added the event listener.

For a more detailed answer check out this question (don't worry about the Flex aspect of it - this relates to standard Actionscript 3 behaviour): What is the difference between target and currenttarget in flex?

You can fix problem setting mouseChildren property to false on MovieClip m. In this case click on textfield will trigger MouseEvent like if user click on m. For clarity:

var m = new menu();
m.mouseChildren = false;
...

I hope this will be usefull to you!
