Answer 1

have you tried putting scrollEnded() on top of bodyScroll()?

function scrollEnded(){
    console.log('scrollEnded. Now do something astounding.');
};
function bodyScroll() {
    console.log('scrolling.');

    if (scrollTimer != -1)
        clearTimeout(scrollTimer);

    scrollTimer = window.setTimeout('scrollEnded()', 500);

};
