Question

ActionScript3.0的问题

import flash.display.Sprite;
import flash.events.*;
var a:Sprite =new Sprite ();
var b:Sprite =new Sprite ();
var c:Sprite =new Sprite ();
a.graphics.beginFill(0xcccccc,1);
a.graphics.drawRect(100,100,100,100);
b.graphics.beginFill(0x212090,1);
b.graphics.drawRect(400,100,100,100);
c.graphics.beginFill(0x000000,1);
c.graphics.drawCircle(300,100,50);
a.buttonMode = true;
b.buttonMode = true;
addChild(b);
addChild(a);
addChild(c);
a.addEventListener(MouseEvent.CLICK,fun1);
b.addEventListener(MouseEvent.CLICK,fun1);
function fun1(evt:MouseEvent)
{
event.currentTarget.addChild(c);
}
function fun1(evt:MouseEvent)
{
event.currentTarget.addChild(c);
}
看一下有什么问题

Answer 1

你把event.currentTarget.addChild(c);
改成evt.currentTarget.addChild(c);就对了。

Answer 2

这个就是画三个图形，a,b是按钮，注册了点击事件，点击后c就添加到相应的按钮中

Answer 3

function fun1(evt:MouseEvent)
{
evt.currentTarget.addChild(c);
}

Answer 4

function fun1(evt:MouseEvent)
{
event.currentTarget.addChild(c);
}
改成
function fun1(evt:MouseEvent)
{
evt.currentTarget.addChild(c);
}
