    text
    copied!<p>I am looping through a small array of file names to grab from a remote server and save locally. This bit works OK.</p> <p>The problem is, I need to run my next function when the downloads are complete.</p> <p>Currently, my function, lets call it step2(), gets called before all the FileStreams can finish (infact, its called before that function even starts!)</p> <p>I read that there is a complete event listener when using openAsynch, but I need to check that all files, e.g. 3 remote swfs) have been written and then start step2() function.</p> <p>How can I go about this?</p> <p>Code below:</p> <pre><code>function onPlaylistComplete(e:Event) { var myArray:Array = new Array(); for each(var i in list_of_files) { myArray.push(i); } for(i = 0; i &lt; myArray.length; i++) { swfItem = myArray[i]; var urlString:String = site_url + myArray[i]; var urlReq:URLRequest = new URLRequest(urlString); var urlStream:URLStream = new URLStream(); urlStream.addEventListener(Event.COMPLETE, urlStreamComplete(swfItem)); urlStream.load(urlReq); } function urlStreamComplete(swfItem):Function { var downloadSwf:Function = function (event:Event):void { var fileData:ByteArray = new ByteArray(); var stream = event.target; stream.readBytes(fileData, 0, stream.bytesAvailable); try { var f : File = File.documentsDirectory.resolvePath(swfItem); var fs : FileStream = new FileStream(); fs.addEventListener(Event.COMPLETE, fileCompleteHandler); fs.openAsync(f, FileMode.WRITE); fs.writeBytes(fileData); } catch (err : Error) { trace(err.message); } } return downloadSwf; } function fileCompleteHandler(e:Event):void { e.target.close(); } step2(); // this seems to run before UrlStreamComplete() } </code></pre>
