Question

我正在使用fileReference，但是我在MAC上的Safari上运行时遇到了问题...

修改以下示例也不适用于MAC上的Safari ...

http://www.permadi.com/blog/2010/06/flash-as3-using-filereference-to-load-files-example-for-flash-cs4-and-above/

PC上的工作流程如下：

创建文件参考
为addEventListener和Event.SELECT

Event.COMPLETE

调用browse()方法

在PC上，选择文件时会触发Event.SELECT。当文件数据可用于Flash时会触发Event.COMPLETE。如果我选择500 MB文件，则在Event.COMPLETE被触发之前需要几秒钟。如果我在Event.COMPLETE被触发之前尝试访问文件数据属性（例如读取数据流），则会收到空引用错误...

到目前为止一直很好......

但是，在MAC（特别是Safari，未经测试的其他浏览器）上，Event.COMPLETE未被触发。

我检查了Adobe文档，其中说上传完成时会触发Event.COMPLETE。所以为什么在fileReference解析文件时会在Windows上被触发，但尚未调用上传方法......

有人可以帮忙吗？

以下是我正在处理的代码的片段：

public function browseFile(target:Object):void 
{
   var imagesFilter:FileFilter = new FileFilter("Allowed files", "*.jpg;*.bmp;*.flv;");
   fileReference.browse([imagesFilter]);
   fileReference.addEventListener(Event.SELECT, fileSelect); 
   fileReference.addEventListener(Event.COMPLETE, fileSelectComplete); 
}  


private function fileSelect(event:Event):void 
{    
   // update label - IMPORTANT for large files as there's a delay while flash parses file, before control is handed back to this script...
   setStatusLabel("...loading file");

   var fileReference:FileReference = event.target as FileReference; 

   fileReference.addEventListener(Event.COMPLETE, fileSelectComplete); 


   // load the file into the fileReference object
   fileReference.load();  

} 


  // Called when upload file has been processed by flash (a few secs for large files, or fileRef.data is null...)
private function fileSelectComplete(event:Event):void 
{
   var fileReference:FileReference=event.target as FileReference; 

   trace("ready to do things - but not fired on Safari on a MAC ");
}

绝对是sdk 3.4的错误我在这里工作了

        var fr:FileReference = e.currentTarget as FileReference;
        fr.addEventListener(Event.COMPLETE, onModelDone);
        fr.addEventListener(ProgressEvent.PROGRESS, onProgress);
//            trace("loading...");
        setTimeout(function():void {fr.load()}, 1);  // put it here for delay

我在sdk3.9上尝试过它仍然是一样的，所以我在这里提交了一个错误： https://bugbase.adobe.com/index.cfm?event=bug&id=3687113

我似乎已经使用DataEvent.UPLOAD_COMPLETE_DATA而不是Event.COMPLETE。

var fileRef:FileReference = new FileReference();
fileRef.addEventListener(Event.SELECT, onFileSelected);
fileRef.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, onUploadComplete);

function onFileSelected(event:Event):void {
    statusBar.text = "File upload started";
    fileRef.upload(FILE_UPLOAD_URL);
};

function onUploadComplete(event:Event):void {
    statusBar.text = "File upload completed";
};

flash cs4文件参考。没有在MAC上调用Event.COMPLETE，
