Flash AS3 text =错误#2124:导入XML时,加载文件是未知类型？

Question

我似乎无法在任何符合我需求的地方找到一个帖子,所以如果在其他地方已经回答,请指导我.

目前正在把我的头发拉出一个不应该发生的错误.我正在制作一个flash网站,里面有一个XML库,正如我之前在很多很多项目中所做的那样(比如这个).但是,当我加载XML文件时,我收到以下错误:

Error #2044: Unhandled IOErrorEvent:. text=Error #2124: Loaded file is an unknown type.

在这个项目中与以前的项目唯一不同的是我在文档类编码中完成所有这些,但到目前为止,这根本不是问题.我真的很困惑为什么flash不喜欢XML文件,我认为还有其他东西会出现这个错误,或者我没有导入一些东西,而不是Flash字面意义上没有识别文件类型.

这是相关的代码:

    public function pg3_setup():void
    {
        trace("Page 3 setup in progress...");
        p3_gallery_loader.load(new URLRequest("flash_scripts/gallery.xml"));
        p3_gallery_loader.addEventListener(Event.COMPLETE,process_gallery);

        function process_gallery(e:Event):void
        {
            trace("Gallery loaded");
            var gallery_xml:XML = new XML(e.target.data);
            image_list = gallery_xml.IMAGE;
            number_of_images = image_list.length();
            container_mask_width = bg.width - p_pad_left - p_pad_right;
            create_container();
            load_thumbs();
        }
    }

我从未进入process_gallery函数,因此从未跟踪"Gallery loaded".对此(可能非常明显)问题的任何帮助都会很棒!

更新:应该也可能包含有问题的XML,尽管据我所知,它与我用于此类事物的每个其他XML文件相同.

没有看到整个代码,我无法确定,但我的猜测是,当它应该 p3_gallery_loader是一个Loader类时,你的对象是一个URLLoader类.

此外,最好在调用load方法之前添加事件侦听器.在连接监听器之前,完整事件可能会触发.

还有一点需要注意:为了避免收到Unhandled IOErrorEvent错误,您应该添加一个事件监听器来处理此错误.否则,如果用户碰巧安装了Flash调试播放器,则会弹出一个丑陋的弹出窗口.

更新的代码块:

p3_gallery_loader.addEventListener(IOErrorEvent.IO_ERROR, onError);
p3_gallery_loader.addEventListener(Event.COMPLETE,process_gallery);
p3_gallery_loader.load(new URLRequest("flash_scripts/gallery.xml"));
