How can i set variable inside addEventListener Clicked Event?

I want to make a clicked function that recognized the item being click, is that possible? Could you teach me ?^^

Here is my try, but It didn't work:

package  {

import flash开发者_高级运维.display.MovieClip;
import flash.events.MouseEvent;


public class main extends MovieClip {
    private var _s1:s1Mc;
    private var _s2:s2Mc;


    public function main() {
        _s1=new s1Mc();
        this.addChild(_s1);
        _s2=new s2Mc();
        this.addChild(_s2);

        _s1.addEventListener(MouseEvent.CLICK,ClickedF(_s1));
        _s2.addEventListener(MouseEvent.CLICK,ClickedF(_s2));
    }
    public function ClickedF(e:MouseEvent,$varMc:MovieClip)
    {
        if($varMc==_s1)
        trace("_s1");
        if($varMc==_s2)
        trace("_s2");
    }
}

}

Here is the Errors:

F:\test\click test\main.as, Line 18 1067: Implicit coercion of a value of type s1Mc to an unrelated type flash.events:MouseEvent.
F:\test\click test\main.as, Line 18 1136: Incorrect number of arguments.  Expected 2.
F:\test\click test\main.as, Line 19 1067: Implicit coercion of a value of type s2Mc to an unrelated type flash.events:MouseEvent.
F:\test\click test\main.as, Line 19 1136: Incorrect number of arguments.  Expected 2.

I understand that I should set 2 things inside the ClickedF of addEventListener but I really don't know how to do it T_T

You can only have one argument in an event handler, but the Event object that comes in has a property currentTarget, which is that object that dispatched the event.

public function main() {
    _s1=new s1Mc();
    this.addChild(_s1);
    _s2=new s2Mc();
    this.addChild(_s2);

    _s1.addEventListener(MouseEvent.CLICK,ClickedF);
    _s2.addEventListener(MouseEvent.CLICK,ClickedF);
}
public function ClickedF(e:MouseEvent)
{ 
    if(e.currentTarget==_s1)
    trace("_s1");
    if(e.currentTarget==_s2)
    trace("_s2");
}

Also, by convention you should start your function names with a lowercase character. Only Class names should start with an uppercase character. This makes your code easier for others to understand, because by convention ClickedF looks like you are passing a reference to a class, not a function. When working in a team of developers sticking to these standards is essential for productivity and is usually a workplace requirement, so it's best to get into the habit now.

Try this:

package  {

import flash.display.MovieClip;
import flash.events.MouseEvent;


public class main extends MovieClip {
    private var _s1:s1Mc;
    private var _s2:s2Mc;


    public function main() {
        _s1=new s1Mc();
        this.addChild(_s1);
        _s2=new s2Mc();
        this.addChild(_s2);

        _s1.addEventListener(MouseEvent.CLICK,ClickedF);
        _s2.addEventListener(MouseEvent.CLICK,ClickedF);
    }
    public function ClickedF(e:MouseEvent):void
    {
        var $varMc:MovieClip = MovieClip(e.currentTarget);
        if($varMc==_s1)
        trace("_s1");
        if($varMc==_s2)
        trace("_s2");
    }
}
}
