Stop JavaScript function after 3 seconds

Question

Heyo,

I want to call a function that disables the scrollwheel while the Preloader is shown. But after the Preloader is gone, the scrollwhell should be usable again. I got the function which disables the scrollwheel allready. Now I need a simple code which makes it run only the first 3 seconds.

My anitscrollwheel function looks like so: window.onwheel = function(){ return false; }

Try this:

<script type="text/javascript">
    var wheelEnabled = false;

    window.onwheel = function() { return wheelEnabled; }

    setTimeout(function() {
        wheelEnabled = true;
    }, 3000);
</script>
