ProgressEvent.PROGRESS вызывается дважды на каждый отсчет (значение) bytesLoaded

trng · 01.04.2013, 04:07

Если через UrlLoader грузить файл (в данном случае чуть больше 800 килобайт - чтобы возникло побольше событий PROGRESS), то на каждый "отсчет" (значение) bytesLoaded событие PROGRESS возникает два раза (кроме последнего "отсчета"). Пробовал в разных браузерах (FF, Opera, Iron) - одно и то же. А в Internet Explorer-е все нормально.
Хотелось бы разобраться - это баг, фича или это как-то настраивается?
В частности, это значит, что прикрученный к такой загрузке некий progressbar будет обновляться в два раза чаще чем необходимо.

Код AS3:

...
urll.addEventListener(ProgressEvent.PROGRESS, loaderOnProgress);
...
protected function loaderOnProgress(e:ProgressEvent):void {
	trace('loaded: ', e.toString());
}

Результат:

Код AS3:

Не вижу проблемы

а вы в прогресс баре храните последние значение и не обновляйте если пришли данные что и в кэше.

Понял. Спасибо.

Зачем?
