Question

I have a web document with scroll. I want to get the value, in pixels, of the current scroll position. When I run the below function it returns the value zero. How can I do this?

<script type="text/javascript" src="js/jquery-1.7.2.js"></script>
<script type="text/javascript" src="js/jquery.mousewheel.min.js"></script>
<script type="text/javascript">
    $(function (){
        $('#Eframe').on("mousewheel", function() {
            alert(document.body.scrollDown)
        }
    })
</script>

Answer 1

Since it appears you are using jQuery, here is a jQuery solution.

$(function() {
    $('#Eframe').on("mousewheel", function() {
        alert($(document).scrollTop());
    });
});

Not much to explain here. If you want, here is the jQuery documentation.
