ccScrollToTop directive doesn't work in IE 11

[ericpanorel]

On a windows 7, 64-bit machine with IE 11, I encountered this issue wherein clicking the scroll to the top chevron up icon doesn't work. My fix was this:

From:

$('body').animate({ scrollTop: 0 }, 500);

To:

$('html, body').animate({ scrollTop: 0 }, 500);
