getting scroll position while user is scrolling.

getting scroll position while user is scrolling.

I am working on an app that I am putting into Cordova.  All is working well except I want to hide part of the header when the user is scrolling down and then show it again when the user gets back to the top of the page.  My problem is it seems that JQM only has scrollStart and scrollStop events which only hides/shows header when the user stops scrolling.  I would prefer to hide/show while the user is scrolling like a native app?  Is this possible? 

Thanks.
