这应该适用于移动应用程序的动作脚本 3，我需要一个类别列表，将我带到产品列表和产品....但我首先在读取值的类别列表上工作从 JSON，我已经有一个 getCategory.php 文档，其中我的 json 被正确返回......但是当我运行 swf 时它说错误......

对我来说，这看起来像是filePath = "getCategories.php";你的问题。
当您在本地或在您的开发环境中运行时，它会在 SWF 所在的同一目录中查找该 php 页面，这可能对您来说可以正常工作。但是当您发布到不再是 php 页面位置的手机时。
因此，由于服务器不存在，您可能会收到 IO 错误。

[编辑] 现在你终于发布了错误，我可以看到你的问题是什么。

type was not found or was not a compile-time constant: Event

说明它找不到 Event 类。
查看您的代码，您也没有导入它。
最接近它的是 MouseEvent。
因此，不要只导入 MouseEvent 试试这个。
