Question

有多个MovieClip将动态放置在舞台上。这些MovieClip被编码为按钮。我想弄清楚 - 当用户点击MovieClip时...找出用户点击的flash舞台上的哪个对象。

内部函数toggleClick我把trace语句：

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

在OUTPUT窗口中：

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

这似乎不是获取被点击的MovieClip名称的方法。

getChildByName（）是这样做的吗？如果是这样，任何想法如何使用getChildByName（）来获取被点击的MovieClip的名称？

Answer 1

在向舞台添加按钮之前，您可以将其命名为

  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';

用你的例子你可以这样做：

  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，当你动态创建一个MovieClip flash时，它会像你看到的那样只读一个实例名（例如instance12）。查找单击哪个movieclip的最佳方法是简单地使用MouseEvent的currentTarget / target（请参阅这两者之间的差异：http://www.wastedpotential.com/?p=10）。

你会像这样使用它：

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;
}

如何在动态创建的Flash舞台上获取MovieClip的名称？
