Action Script 3.0中的呼叫按钮

Question

I am trying to make button panel. each button have two type btn_home and btn_home_white I am trying to reach those buttons.It is work if I write for each button their own methods like

btn_home.addEventListener(MouseEvent.MOUSE_OVER,overEffect);
btn_home_white.addEventListener(MouseEvent.MOUSE_OUT,outEffect);

   function overEffect(e:MouseEvent)
{
var myTweenHight:Tween = new Tween( btn_home,"height",Bounce.easeOut,25,0,3,true);

var myTweenHight2:Tween = new        Tween(btn_home_white,"height",Bounce.easeOut,0,25,3,true);
var myTweenAlpha:Tween = new Tween(btn_home_white,"alpha",Strong.easeOut,0,1,2,true);

}

function outEffect(e:MouseEvent)
{
var myTweenHight:Tween = new Tween btn_home,"height",Bounce.easeOut,0,25,3,true);

var myTweenHight2:Tween = new Tween(btn_home_white,"height",Bounce.easeOut,25,0,3,true);
var myTweenAlpha:Tween = new Tween(btn_home_white,"alpha",Strong.easeOut,1,0,2,true);

}

But I have 10 buttons as btn_buttonname and btn_buttonname_white . I tryed to create Event listener on stage for all.It works for firts type buttons btn_buttonname but How can I get second type buttons? I tryed e.target["_white"] but it does not work .

stage.addEventListener(MouseEvent.MOUSE_OVER , overEffect);
stage.addEventListener(MouseEvent.MOUSE_OUT , outEffect);

function overEffect(e:MouseEvent)
{
var myTweenHight:Tween = new Tween(e.target,"height",Bounce.easeOut,25,0,3,true);
trace("height");
var myTweenHight2:Tween = new        Tween(e.target["_white"],"height",Bounce.easeOut,0,25,3,true);
var myTweenAlpha:Tween = new Tween(e.target["_white"],"alpha",Strong.easeOut,0,1,2,true);

}

function outEffect(e:MouseEvent)
{
var myTweenHight:Tween = new Tween(e.target,"height",Bounce.easeOut,0,25,3,true);

var myTweenHight2:Tween = new Tween(e.target["_white"],"height",Bounce.easeOut,25,0,3,true);
var myTweenAlpha:Tween = new Tween(e.target["_white"],"alpha",Strong.easeOut,1,0,2,true);

}

EDIT: I made it work as Daniel Carvalho sad adding for each buttons event listener.Now it works but if I move out mouse on button to other button previous button does not turn original form .

btn_home.addEventListener(MouseEvent.MOUSE_OVER,overEffect);
btn_home_white.addEventListener(MouseEvent.MOUSE_OUT,outEffect);
btn_contact.addEventListener(MouseEvent.MOUSE_OVER,overEffect);
btn_contact_white.addEventListener(MouseEvent.MOUSE_OUT,outEffect);
btn_menu.addEventListener(MouseEvent.MOUSE_OVER,overEffect);
btn_menu_white.addEventListener(MouseEvent.MOUSE_OUT,outEffect);
btn_restaurant.addEventListener(MouseEvent.MOUSE_OVER,overEffect);
btn_restaurant_white.addEventListener(MouseEvent.MOUSE_OUT,outEffect);
btn_rezervation.addEventListener(MouseEvent.MOUSE_OVER,overEffect);
btn_rezervation_white.addEventListener(MouseEvent.MOUSE_OUT,outEffect);

Answer 1

Your e.target should work, though you don't (as far as I can see) need the [_"white"] after e.target for your _white buttons. The reason the e.targets aren't working is because you're just adding event listeners to the stage, and not the individual buttons.

I see two choices (perhaps there are others): manually go through writing event listeners for each button, or put all the buttons that will use the overEffect function into one Array, and all the buttons using the outEffect function into another Array.

Then create two for loops, and go through those Arrays adding the event listeners to each child of the array. Your e.target code should work at that point.

Let me know if you have any trouble with that, hope it helps.

Here is a quick example that may help you:

http://wonderfl.net/c/vhay

function createButton():MovieClip{
    var button:MovieClip=new MovieClip();
    var stateA:Shape=new Shape();
    var g:Graphics = stateA.graphics;
    g.beginFill(0xFF0000);
    g.drawRect(0, 0, 10, 10);
    g.endFill();
    button["stateA"] = stateA;
    button.addChild(stateA);
    var stateB:Shape=new Shape();
    g = stateB.graphics;
    g.beginFill(0x00FF00);
    g.drawRect(0, 0, 10, 10);
    g.endFill();
    button["stateB"] = stateB;
    button.addChild(stateB);
    stateB.visible=false;
    return button;
}
var nbButtons:int=10;
var buttons:Array=[];
var selectButton:MovieClip;
for (var i : int = 0;i < nbButtons; i++) {
    var button:MovieClip=createButton();
    addChild(button);
    button.y=10;
    button.x=i*12+10;
    addChild(button);
    buttons.push(button);
    setUpButton(button);
}
function setUpButton(button:MovieClip):void {
    button.buttonMode=true;
    button.addEventListener(MouseEvent.ROLL_OVER, buttonRollOver);
    button.addEventListener(MouseEvent.ROLL_OUT, buttonRollOut);
    button.addEventListener(MouseEvent.CLICK, buttonClick);
}
function buttonClick(e:Event):void{
    switchButtonStateToNotSelected();
    switchButtonStateToSelected(e.currentTarget as MovieClip);
}
function switchButtonStateToSelected(button:MovieClip):void{
    button.buttonMode=true;
    button.removeEventListener(MouseEvent.ROLL_OVER, buttonRollOver);
    button.removeEventListener(MouseEvent.ROLL_OUT, buttonRollOut);
    button.removeEventListener(MouseEvent.CLICK, buttonClick);
    button["stateA"]["visible"]=false;
    button["stateB"]["visible"]=true;
    selectButton=button;
}
function switchButtonStateToNotSelected():void{
    if(selectButton) {
        setUpButton(selectButton);
        selectButton["stateA"]["visible"]=true;
        selectButton["stateB"]["visible"]=false;
        selectButton=null;
    }
}
function buttonRollOver(e:Event):void{
    e.currentTarget["stateA"]["visible"]=false;
    e.currentTarget["stateB"]["visible"]=true;
}
function buttonRollOut(e:Event):void{
    e.currentTarget["stateA"]["visible"]=true;
    e.currentTarget["stateB"]["visible"]=false;
}
