Pause a running setInterval function?
<p>I have 4 functions running on setInterval (tscrolls) which just animate a div's top location every couple of seconds as soon as the document is loaded.</p>

<pre><code>var intervalFunctions = [ tScroll1, tScroll2, tScroll3, tScroll4 ];
var intervalTimer = 3000;
window.setInterval(function(){
  intervalFunctions[intervalIndex++ % intervalFunctions.length]();
}, intervalTimer);
</code></pre>

<p>Is there a way to pause this on mouseenter or hover?</p>
