希望这是一个很容易的问题：）

hoping this is an easy enough question :)

一些细节： 我使用Flash CS5，从来没有碰过的Flex。同样是做加载的SWF将是一个客户端 SWF，所以希望这可以与一个简单的几行的解决方案。

Some details: I am using Flash CS5, never touched Flex. Also the SWF that is doing the loading will be a client SWF, so hoping for a solution that could work with a simple couple of lines.

基本上里面我工作的SWF只包含一个简单的字符串：

Basically inside the SWF I am working on contains just a simple string:

var theString = "theString";
trace("theString = "+theString);

现在我一直在测试加载器SWF，将载入我的字符串SWF并获得最简单的方法变量。有什么想法吗？下面是我目前的破code：

Now I've been working on a test loader SWF that will load my String SWF and get the variable in the simplest way. Any thoughts? Below is my current broken code:

function loaderComplete(event:Event)
    {
        trace("... in loaderComplete");

        getString = loader.content.toString();

        trace("loader.content = "+loader.content);
        trace("... getString    = "+getString);
    }

这是我的输出窗口：

theString = theString
... in loaderComplete
loader.content = [object MainTimeline]
... getString  = [object MainTimeline]

我搜索的堆栈，发现类似的问题，但没有一个是正是我需要的：

I've searched on Stack and found similar questions, but none are exactly what I need:

跟踪的视频文件 - 嵌入FLV到SWF

^基本上我想要做的一样好，没有解答

^ Basically what I'm trying to do as well, no answers yet

to从一个SWF传递变量，以在AS3 另一个SWF

^听起来就像我的问题，但答案是Flex应用程序的例子

^ sounded just like my problem, but answer was a Flex application example

pass VAR值从一个SWF谁是firts人在里面装在AS3 另一个SWF

^这是接近，但我不知道如何实现所选择的答案，也似乎更多的是有点复杂的话，我需要

^ This was close, but am not sure how to implement the chosen answer, also seems a bit more intricate then I need

请帮忙！

推荐答案

让我们澄清一下：  1.装载器SWF，我们将调用父。  2.父加载的SWF中，我们将调用子。

Let's clarify a bit: 1. The loader swf, we will call the parent. 2. The swf loaded by the parent we will call the child.

孩子包含字符串，并且希望家长能够读取该字符串> 所以... 孩子必须定义字符串公共变量。 （这意味着你必须使用一个类文件吧，因为你不能在时间轴上声明属性public。）

The Child contains a string, and you want the parent to be able to read that string> So... The Child must define a public variable for the string. (This means you have to use a Class file for it, since you cannot declare a property public on the timeline.)

最后，家长将尝试并获得该属性。您可能需要包装在一个try / catch来处理情况，该字符串不会以present。

Finally, the parent will try and get that property. You may want to wrap that in a try/catch to handle cases where the string will not be present.

下面是一个例子子类。

Here is an example Child Class.

package  
{
import flash.display.Sprite;

/**
 * ...
 * @author Zach Foley
 */
public class Child extends Sprite 
{
    public var value:String = "This is the child Value";
    public function Child() 
    {
        trace("Child Loaded");
    }

}

}

这里是父类加载器：

 package  
{
import flash.display.Loader;
import flash.display.Sprite;
import flash.events.Event;
import flash.net.URLRequest;

/**
 * ...
 * @author Zach Foley
 */
public class Parent extends Sprite 
{
    private var loader:Loader;

    public function Parent() 
    {
        trace("PArent Init");
        loader = new Loader();
        loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaded);
        loader.load(new URLRequest("child.swf"));
    }

    private function onLoaded(e:Event):void 
    {
        trace("Child Loaded");
        trace(loader.content['value']);
    }

}

}

输出将是： 家长初始化 儿童加载 儿童加载 这是孩子的价值

The Output will be: PArent Init Child Loaded Child Loaded This is the child Value
