files.browse([new FileFilter("图片", "*.jpg;*.gif;*.png", "bmp")]);

protected function onSelectFiles(event:Event):void
{

    for each (var f:FileReference in files.fileList)
    {

        var fileItem:Object=new Object;
        fileItem.file=f;
        fileItem.name="NoName";
        fileItem.typeid=11;
        fileItem.filename=f.name;
        selectFiles.addItem(fileItem);
    }

}
protected function uploadI_clickHandler(event:MouseEvent):void
{
        if (selectFiles.length > 0)
        {

            var item:Object=selectFiles.removeItemAt(0);

            var curl:CURL=new CURL;
            curl.url="UploadImageServlet";
            curl.setData("name", item.name);
            curl.setData("type", item.typeid);
            curl.setData("imagedesc", item.imagedesc);
            var file:FileReference=item.file as FileReference;
            if (file != null)
            {
                file.addEventListener(Event.COMPLETE, onFileUploadComplete);
                file.upload(curl.urlRequest);
            }

        }
        
}
    protected function onFileUploadComplete(event:Event):void
{
    var f:FileReference=event.currentTarget as FileReference;
    f.removeEventListener(Event.COMPLETE, onFileUploadComplete);
    uploadI_clickHandler(null);
}
