多个 URLLoader

发布于 2024-09-04 07:05:15 字数 751 浏览 8 评论 0原文

我正在使用 URLLoader 加载多个 xml 文件。

for (var i=0;i<xmlCount;i++) {
     loadXML(xmlFiles[i], i);
}

public function loadXML(req:String=null, _id:Number=0):void {
     var loader:URLLoader = new URLLoader();
     loader.addEventListener(ProgressEvent.PROGRESS, 
             function a(e:ProgressEvent) {XMLLoadProgress(e, _id);});
     loader.addEventListener(Event.COMPLETE, XMLLoadFinished);
     loader.load(new URLRequest(req));

}

private function XMLLoadProgress(e:ProgressEvent=null, _id:Number=0):void {
     dispatchEvent(new LoadingEvent(Model.LOADING_PROGRESS, _id, (e.bytesLoaded/e.bytesTotal)*100));
}

问题是我认为 LOADING_PROGRESS 在所有加载完成后被调度，并且每个 xml 都被一一加载，而不是异步加载。

我怎样才能使其异步加载，并使其为每个进度标记调用进度事件。

I am loading multiple xml files with URLLoader.

for (var i=0;i<xmlCount;i++) {
     loadXML(xmlFiles[i], i);
}

public function loadXML(req:String=null, _id:Number=0):void {
     var loader:URLLoader = new URLLoader();
     loader.addEventListener(ProgressEvent.PROGRESS, 
             function a(e:ProgressEvent) {XMLLoadProgress(e, _id);});
     loader.addEventListener(Event.COMPLETE, XMLLoadFinished);
     loader.load(new URLRequest(req));

}

private function XMLLoadProgress(e:ProgressEvent=null, _id:Number=0):void {
     dispatchEvent(new LoadingEvent(Model.LOADING_PROGRESS, _id, (e.bytesLoaded/e.bytesTotal)*100));
}

The problem is I think LOADING_PROGRESS gets dispatched after all the loading is done and each xml is loaded one by one not asynchronously.

How could I make it load asynchronously and also make it so progress event is called for each progress tick.

我猜这只在通过快速连接查看时才会发生。尝试使用慢速连接查看（Charles Proxy 能够人为地减慢您的连接速度）。

您可以自定义 URLLoader。

public function SequenceLoader extends URLLoader {
    private var index:int;

    public function SequenceLoader(index:int) {
        this.index = index;
    }
}

然后在每个 loadXML 中，标记加载器：

public function loadXML(req:String=null, _id:Number=0):void {
     var loader:SequenceLoader = new SequenceLoader(_id);
     loader.addEventListener(ProgressEvent.PROGRESS, 
             function a(e:ProgressEvent) {XMLLoadProgress(e);});
     loader.addEventListener(Event.COMPLETE, XMLLoadFinished);
     loader.load(new URLRequest(req));
}

private function XMLLoadProgress(e:ProgressEvent=null):void {
   var loader:SequenceLoader  = e.target as SequenceLoader;
   var loaderIndex:int = loader.index;
  //do other stuff
}

You can customize the URLLoader.

public function SequenceLoader extends URLLoader {
    private var index:int;

    public function SequenceLoader(index:int) {
        this.index = index;
    }
}

then in each loadXML, mark the loader:

public function loadXML(req:String=null, _id:Number=0):void {
     var loader:SequenceLoader = new SequenceLoader(_id);
     loader.addEventListener(ProgressEvent.PROGRESS, 
             function a(e:ProgressEvent) {XMLLoadProgress(e);});
     loader.addEventListener(Event.COMPLETE, XMLLoadFinished);
     loader.load(new URLRequest(req));
}

private function XMLLoadProgress(e:ProgressEvent=null):void {
   var loader:SequenceLoader  = e.target as SequenceLoader;
   var loaderIndex:int = loader.index;
  //do other stuff
}
