如何在動態創建的Flash舞臺上獲取MovieClip的名稱？

Question

有多個動態放置在舞臺上的動畫片段。這些影片剪輯被編碼爲按鈕。我試圖弄清楚 - 當用戶點擊MovieClip時...找出用戶點擊Flash階段的哪個對象。

內部功能toggleClick我把跟蹤聲明：

trace("movieClip Instance Name = " + e.target.name); 

在輸出窗口：

movieClip Instance Name = instance5 
movieClip Instance Name = instance12 
movieClip Instance Name = instance5 
movieClip Instance Name = instance32 
movieClip Instance Name = instance5 
movieClip Instance Name = instance59 

似乎不是得到一個名字被點擊的影片剪輯的方式。

是getChildByName（）的方式嗎？如果是這樣，任何想法如何使用getChildByName（）來獲取被點擊的MovieClip的名稱？

Answer 1

添加一個按鈕到舞臺前，你其實可以將其命名爲

var myButton:MovieClip = new MovieClip(); 
    myButton.name = 'button1'; 

或

var myButton:MovieClip = new MyButton(); //if you assigned a class name to your MovieClip 
    myButton.name = 'button1'; 

與您例如，你可以做這樣的事情：

var comp:Comp = new Comp(); 
    var monitor:Monitor = new Monitor(); 

    addItemButton(comp, "comp" , {x:100, y:200}); 
    addItemButton(monitor, "monitor" , {x:30 , y:50}); 


    private function addItemButton(item:MovieClip , itemName:String , params:Object):void 
    { 
    item.addEventListener(MouseEvent.CLICK , clickHandler); 
    item.name = itemName; 

    // of course params is not necessary, just making a point of 
    // how to centralize your concerns 
    item.x = params.x; 
    items.y = params.y; 

    addChild(item); 
    } 

    private function clickHandler(event:MouseEvent):void 
    { 
    trace("button clicked:" + event.currentTarget.name); 
    }

在AS3中，當您創建MovieClip動態Flash時，會將它視爲只讀實例名稱，如您所見（例如，instance12）。找到哪個movieclip被點擊的最好方法是簡單地使用MouseEvent的currentTarget/target（請參閱這兩者之間的區別：http://www.wastedpotential.com/?p=10）。

你會使用它，像這樣：

var foo:MovieClip = new MovieClip(); 
foo.graphics.drawRect(0, 0, 100, 50); 
stage.addChild(foo); 
foo.addEventListener(MouseEvent.CLICK, clickHandler); 

var bar:MovieClip = new MovieClip(); 
bar.graphics.drawRect(0, 0, 100, 50); bar.y = 100; 
stage.addChild(bar); 
bar.addEventListener(MouseEvent.CLICK, clickHandler); 

//this function will set the x to 100 and the width to 50 of the clicked MovieClip 
function clickHandler(e:MouseEvent):void 
{ 
    e.currentTarget.x = 100; 
    e.currentTarget.width = 50; 
}
