Answer 1

I would suggest First of all create a javascript function

// Attaching scroll event when document/window is loaded
    function OnFirstLoad() {
        if (document.attachEvent) {
            document.attachEvent('onscroll', scrollEvent);
        } else if (document.addEventListener) {
            document.addEventListener('scroll', scrollEvent, false);
        }

    }

then, use either

        window.onload = OnFirstLoad;

Or

    $(document).ready(function () {
         OnFirstLoad();
    });

In This scroll event is a function

function scrollEvent(e) {
        var body = document.body,
             html = document.documentElement;

        var docHeight = Math.max(body.scrollHeight, body.offsetHeight,
                               html.clientHeight, html.scrollHeight, html.offsetHeight);
        var currentScroll = (document.documentElement && document.documentElement.scrollTop) || document.body.scrollTop;
        // implement your logic according to requirement

    }
