        /* 
            In our real app, we would load in the categories from our database (via a JSON)

        filePath = "getCategories.php"; //declare path and file name
        myReq = new URLRequest(filePath); //create URLRequest to access the file

        myLoader = new URLLoader(); //create URLLoader to load the file

        myLoader.removeEventListener(Event.COMPLETE, loadComplete);

        myLoader.load(myReq); //start loading a file with our URLLoader instance

            trace(aCategory.categoryid);
        }

        ///////////////
        // Consider that it would be more responsible to add these to an array and maintain 
        // which are being added/deleted, then we could create a print function!
        ///////////////
    }

    //if any error was thrown, event was also dispatched and now you can print
    //the error description to the text field.
    public function ioErrorHandler(e:IOErrorEvent):void
    {
         trace("There was a problem loading "+filePath+": "+e);
    }

}

}

        // for each "category" in our list (Array)...
        for (var count in categories)
        {
            // Create a button for each of the categories that exist in our Array
            var aCategory:BtnCategory = new BtnCategory(categories[count].category);

            // Add the BtnCategory to the stage
            aCategory.x = 0;
            aCategory.y = lastButtonEndedY;
            aCategory.name = categories[count].id; // give it a unique name!
            addChild(aCategory);

            lastButtonEndedY += (aCategory.getHeight() + 1);
        }

        addEventListener(MouseEvent.CLICK, mouseClicked);

这应该适用于移动应用的动作脚本3，我需要一个类别列表，将我带到产品列表和产品....但我首先在类别列表上工作从JSON读取值，我已经有一个getCategory.php文件，我的json正确返回.....但当我运行swf它说错误....

对我来说，filePath = "getCategories.php";似乎是你的问题当您在本地或在您的开发环境中运行时，它将在SWF所在的同一目录中查找该页面，这可能对您有用。但是当你发布到不再是php页面位置的手机时因此，您可能会收到IO错误，因为服务器不存在。

[编辑] 那么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

声明无法找到Event类查看您的代码也不会导入它。
你最接近它的是MouseEvent 因此，不要只是导入MouseEvent，而是尝试这个。

import flash.events.*;

我有一个错误，它不起作用，这是错误
