嗨，我对 AS3 很陌生，我正在尝试将一些数据从 php 解析为 VO 文件，然后将数据字符串传输到另一个 .as 文件中，它将数据放入框中。我被困在如何将VO文件中的数据解析到另一个.as文件中（将数据从php提取到BookVO，然后将BookVO解析到VectorTest）。我尝试在 BookVO 中跟踪数据，它工作正常，但我无法将数据从 BookVO 获取到 VectorTest。

请帮忙，谢谢

首先，你的课做得很好。比大多数自称是 AS3 新手的人要好得多。;)

那就是说...

  • 在VectorTest中，您正在调用super()MovieClip。你不需要这个。
  • 如果您不使用 MovieClip 的时间线（我建议您不要使用它），请Sprite改为扩展；它很轻，因为它不携带 MovieClip 的时间线包袱。
  • 您for loop在 VectorTest 构造函数中的第一个循环到length... 没有数组。
  • 您正在覆盖该循环中的属性，BookVO该循环应由您的URLLoader. 这是多余的。
  • 您的第二个循环引用 4 个属性BookVO，既不报告也不设置变量（即books[j].nobed1;）。可能想删除它。
  • 在BookVO中，您编写了一个嵌套函数。除非您要处理大量变量并且变量范围存在问题，否则不要这样做。就目前而言，唯一Jandler()正在访问的变量已经是类级别的全局变量。

加载数据是一个异步操作，这意味着数据不会立即填充（LoadRequest > Wait > ProgressEvent > Wait > LoadComplete）。因为您BookVO在同一个函数中实例化和读取属性，所以您将得到的只是空属性。与VectorTest构造函数不同，因为Jandler()是Event.COMPLETE（异步）调用的，所以它可以访问您要查找的变量。

试试这个...

您仍然需要解决length要实例化的书籍数量，但是，我已经将您从构造函数中读取的属性分开，并添加了对加载完成时调用的方法的引用。

它会打印出所有变量，如果它是 Vector 中的最后一本书，它会调用finish()which... um... 完成您正在做的其他事情。:)
