Build a js script

Note - this must not reply on JQuery

I'm looking for some JS which will:

Detect how far the user has scrolled down the page.

When the user stops scrolling (after a configurable amount of time in ms) when a scroll position is considered stable, it should fire the percentage scrolled to a URL endpoint using a function like:

function firepixel(scrollnum){

// Fire the pixel

var img = [login to view URL]("img");

[login to view URL]("src", btPixel(scrollamount));

[login to view URL]("style", "display:none");

[login to view URL](img);


This script will be sent to page from a 3rd party server, so will need to ensure it's looking at the total page
