Ionic: get ionicScroll onScroll event
提问by Christian Benseler
I found this thread that tells how to get the scroll event of a ionicScroll:
我发现这个线程告诉如何获取 ionicScroll 的滚动事件：
http://forum.ionicframework.com/t/ionicscrolldelegate-doesnt-have-a-onscroll-event/19497
http://forum.ionicframework.com/t/ionicscrolldelegate-doesnt-have-a-onscroll-event/19497
$ionicScrollDelegate.getScrollView().onScroll = function () {
console.log($ionicScrollDelegate.getScrollPosition());
};
But this doesn't work. The official doc doesn't have anything about this. Any clue?
但这不起作用。官方文档对此没有任何说明。有什么线索吗？

If you simply want to listen to to the scroll event maybe the easiest way would be to use the on-scrolldirective.
如果您只是想收听滚动事件，那么最简单的方法可能是使用on-scroll指令。
