actionscript-3 - AS3 #1063: var count 不匹配 onSym01() 预期为 0，得到 1

Question

我正在尝试向舞台添加一个符号，但我遇到了参数错误。

我的代码：

symHolder.mc.sym01_mc.addEventListener(MouseEvent.MOUSE_DOWN, startDragHandler);

function startDragHandler(event:MouseEvent):void {
    var ClassReference:Class = getDefinitionByName("Sym" + event.target.name.charAt(3) + event.target.name.charAt(4)) as Class;
    var s:MovieClip = (new ClassReference("s" + num) as MovieClip);
    s.x = mouseX;
    s.y = mouseY;
    toggleSymHolder(null);
    addChild(s);
    s.name = "s" + num;
    stage.addEventListener(MouseEvent.MOUSE_UP, stopDragHandler);
    s.startDrag();
    s.addEventListener(MouseEvent.MOUSE_DOWN, nextDrag);
    num ++;
}

Answer 1

类构造函数是否接受任何参数？如果不"s"+num从构造函数中删除。

(new ClassReference("s" + num) as MovieClip); 

应该 ：

(new ClassReference() as MovieClip);
