之前没怎么注意, 一直用MouseEvent.DOUBLE_CLICK来监听DataGrid的双击事件. 但这样会造成即使在空行双击也会激发响应.
datagridClasses.doubleClickEnabled = true;
datagridClasses.addEventListener(MouseEvent.DOUBLE_CLICK, onDGDoubleClicked);
正确方法应该使用ListEvent.ITEM_DOUBLE_CLICK监听项目双击事件.
datagridClasses.addEventListener(ListEvent.ITEM_DOUBLE_CLICK, onDGDoubleClicked);
权限验证:
var fileRef:FileReference = new FileReference();
var request:URLRequest = new URLRequest(serviceUrl);
request.method = URLRequestMethod.POST;
var encoder : Base64Encoder = new Base64Encoder();
encoder.encode(userName + ":" + password);
request.requestHeaders.push(new URLRequestHeader("Authorization", "Basic " + encoder.toString())); // ** 增加认证信息
fileRef.addEventListener(Event.OPEN, onFileDownloadBegin);
fileRef.addEventListener(Event.COMPLETE, onFileDownloadComplete);
fileRef.addEventListener(IOErrorEvent.IO_ERROR, onFileDownloadError);
fileRef.addEventListener(Event.CANCEL, onFileDownLoadCancel);
fileRef.download(request, getExportFileName(serviceUrl));
