Is there a code that can find on which movieclip I clicked?

I'm making a game in AS3.

I've got a scene with empty space. There are empty space 1, empty space 2...etc

When the player click on an empty space, a usebox appear with 2 buttons. It the same usebox for all the empty spaces. When the player click on the buttons "buy" a windows appears where he can choose between different buildings (same windows for all the empty spaces).

When he clicks on the building that he wants, the function "build" is called (someBuilding.visible = true) and the building appears on the scene.

But, I don't how to tell the code to make the building corresponding to the empty space visible..

If the player has clicked on the empty space 2 for example, how can I tell the code to make someBuilingInEmptySpace2.visible = true? If he has clicked on the empty space 3 --> someBuilingInEmptySpace3.visible = true?

something like:

function build():void{
if clicked on emptyspace2 {
 someBuilingInEmptySpace2.visible = true ; }
if clicked on emptyspace3 {
..
.

EDIT

Thank you for your answers, but I don't really see where to put it. Here's my code:

I've got Engine.as where the elements of the game are:

private function createBackground(thisBack:String):void{
for (i in usableItems){
                var thisClip = usableItems[i];
                thisClip.buttonMode = true;
                thisClip.addEventListener(MouseEvent.CLICK, examine, false, 0, true);
                thisClip.gotoAndStop(1);
            }
private function createUI():void{
            
            toolbar = new Toolbar(stage);
            addChild(toolbar);
            toolbar.x = 0;
            toolbar.y = 400;
                        
            buildings = new Buildings(stage);
            addChild(buildings);
            buildings.visible = false;
            
puzzle = new Puzzle(stage);
            
            stage.addEventListener("endGame", endGame, false, 0, true);
        }

private function examine(e:MouseEvent):void{
                stage.dispatchEvent(new Event("itemClicked"));
                    useBox = new UseBox(stage, e.currentTarget);
                    useBox.x = mouseX;
                    useBox.y = mouseY;
                    stage.addChild(useBox);
                }

So when the player clicks on an empty space (emptyspace2 for exemple), the function examine is called and the useBox appears.

In my UseBox.as :

public function UseBox(stageRef:Stage, thisThing:Object){
this.stageRef = stageRef;
this.thisThing = thisThing;
this.visible = true;
            useButton.buttonMode = true;
            lookButton.buttonMode = true;
            lookButton.addEventListener(MouseEvent.CLICK, lookAt, false, 0, true);
            useButton.addEventListener(MouseEvent.CLICK, useThing, false, 0, true);

private function useThing(e:MouseEvent):void{
Engine.buildings.visible = true;
        useButton.removeEventListener(MouseEvent.CLICK, useThing);
            }

In my Buildings.as

public function Batiments(stageRef:Stage){
houseBtn.addEventListener(MouseEvent.CLICK, houseConstruction, false, 0, true);

}
private function houseConstruction(e:MouseEvent):void{
            var house;
            var emptyspace1;
                    trace("choix");
                stage.dispatchEvent(new Event("itemClicked"));
            Engine.buildings.visible = false;
            Engine.puzzle.houseBuilt();
            toolbar.money.text = String( Number(toolbar.money.text ) - 100 );
                }

And, finally, in my Puzzle.as

public function Puzzle(stageRef:Stage){
allPuzzles = new Object;
allPuzzles.tundra.maisonBought = false;
}

public function maisonBuilt():void{
            var house;
            var emptyspace1;
            for (var i in Engine.usableItems){
            if (Engine.usableItems[i].displayName == "HOUSE")
                house = Engine.usableItems[i];
            if (Engine.usableItems[i].displayName == "EMPTYSPACE1")
                emptyspace1= Engine.usableItems[i];
                    }
            allPuzzles.tundra.houseBought = true;
            house.visible = true;
            house.gotoAndStop("contruction");
            house.lookTag = "1";
            timeConstruction.addEventListener(TimerEvent.TIMER_COMPLETE, constructionFini);
                    timeConstruction.start();
            emptyspace1.visible = false;
}

Where should I put the emptyspace listeners? Have I made too many classes?

addEventListener(MouseEvent.CLICK, onSpaceClicked);
function onSpaceClicked(event:MouseEvent):void 
{
    if ( event.target === emptySpace1 ) {
      // case 1...
    } else if ( event.target === emptySpace2 ) {
      // case 2...
    } else if ( event.target === emptySpace3 ) {
      // case 3...
    } 
}

This can be accomplished by checking either the target or currentTarget property of the Event:

// you should probably do this part in a loop of some sort.
emptySpace1.addEventListener(MouseEvent.CLICK, onSpaceClicked);
emptySpace2.addEventListener(MouseEvent.CLICK, onSpaceClicked);
emptySpace3.addEventListener(MouseEvent.CLICK, onSpaceClicked);

function onSpaceClicked(evt:MouseEvent):void 
{
    var clickedSpace:MovieClip = evt.currentTarget as MovieClip;
    //... perform the actions you need to perform on the clickedSpace
}
