I have a problem with ionic framework's native scroll. The following works fine in the browser, but not when compiled to iOS. If I poll the
$ionicScrollDelegate.getScrollPosition() at an interval, I don't get up-to-date values for positions. It's only if the deceleration ends or the user touches again that the value is updated. I spelunked through all the ionic scroll code, but it seems that the
__scrollLeft value comes from an even deeper internal API since I'm trying to use native, not js scrolling.
In an attempt to hack around it, I tried using the DOM API to get the window-relative position of my content:
inversePosition = divContainer.getBoundingClientRect().left;
but this suffered from the same lack of updates. This makes me think it may not even be possible.
Is there a way to get the position more directly? I'm willing to dive into the ionic js bundle myself, but I don't know where to start in terms of even finding the core cordova scrolling API documentation.
Basically, my use-case is similar to that of a mapping app, I need realtime accurate scroll position data.
I opened an issue in the ionic lib, but I doubt anyone will get to it with 398 other open issues....
tagging phonegap because because phonegap wraps cordova as well, and solutions in phonegap may be applicable to this problem.
I haven't used it in ionic projects, only in backbone-cordova projects, but I suppose that it will work the same.
