如何将字符串从 SWF 传递到另一个 SWF [英] How to pass a String from a SWF into another SWF

问题描述

希望这是一个足够简单的问题:)

hoping this is an easy enough question :)

一些细节:我使用的是 Flash CS5，从未接触过 Flex.此外，正在加载的 SWF 将是一个客户端 SWF，因此希望有一个可以使用简单几行代码的解决方案.

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.

基本上在我正在处理的 SWF 中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);

现在我一直在研究一个测试加载器 SWF，它将加载我的字符串 SWF 并以最简单的方式获取变量.有什么想法吗?以下是我当前损坏的代码:

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]

我在 Stack 上搜索并发现了类似的问题，但没有一个是我需要的:

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

跟踪视频文件 - 将 flv 嵌入到 swf

^ 基本上我也在尝试做的，还没有答案

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

将变量从一个 swf 传递到as3 中的另一个 swf

^ 听起来就像我的问题，但答案是一个 Flex 应用程序示例

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

将 var 值从一个 swf 传递到另一个加载在 AS3 中的第一个 swf 中的 swf

^ 这已经很接近了，但我不确定如何实现所选的答案，而且似乎比我需要的更复杂

^ 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.加载器swf，我们会调用父.2. 父级加载的swf，我们将调用子级.

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.

Child 包含一个字符串，并且您希望父级能够读取该字符串>所以...Child 必须为字符串定义一个公共变量.(这意味着您必须为此使用 Class 文件，因为您不能在时间轴上声明属性为 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，父级将尝试获取该属性.您可能希望将其包装在 try/catch 中以处理不存在字符串的情况.

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.

这是一个示例子类.

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");
    }

}

}

这是父加载器类:

 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:父初始化儿童装载儿童装载这是孩子的价值

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