Don't allow to scroll the page when popup shows

Hey all, I have a problem with my current image gallery. When someone clicks on the thumbnail the hidden big div shows the enlarged picture (like a popup). I have a semi transparent div over the whole page then to darken it out.

Now I would like to disable the scrolling of the page, while the div is showing. I have to do it with javascript no jquery though as it is for a school project.

Any ideas?

Hey Aaron, thanks for the reply, this is my code atm:

js: 

var scrollThePage;

function scrollToTop() {
        if (scrollThePage == null) {
        var scrollStep = -window.scrollY / 25;
        scrollThePage = setInterval(function(){
        if ( window.scrollY > 0 ) {
            window.scrollBy( 0, scrollStep );
        }
        else { 
            clearInterval(scrollThePage);
            scrollThePage = null;
        } 
    },25);
}
}

and in html it is: 

  <div id="scrollToTop" onclick="scrollToTop()">
                <p>&nbsp;</p>
            </div>
