Stopping Effect.ScrollTo() while it's scrolling?

Yeah, basically I have this:

Effect.ScrollTo("bottom", { duration: 5.0 });

So what I want is to stop this effect while it's scrolling whenever I want to.

Any help?

Solution 
  • var scrollEffect = Effect.ScrollTo("bottom", { duration: 5.0 });

...

scrollEffect.cancel();

    This code below works perfectly for me:

    <html>
<head>
    <script src="js/prototype.js" type="text/javascript"></script>
    <script src="js/scriptaculous.js" type="text/javascript"></script>

    <style type="text/css" media="screen">
        body { font-size: 30px; }
        #destination { margin-top: 1400px; }
        #start { position: fixed; top: 10px; left: 20px;}
        #stop { position: fixed; top: 50px; left: 20px;}
    </style>

    <script type="text/javascript" charset="utf-8">
        function startEffect() {
            scrollEffect = Effect.ScrollTo("destination", { duration: 8.0 }); return false;
        }

        function stopEffect() {
            scrollEffect.cancel(); return false;
        }
    </script>
</head>
<body>
    <a id="start" href="#" onclick="return startEffect();">Start Effect</a>
    <a id="stop" href="#" onclick="return stopEffect();">Stop Effect</a>
    <p id="destination">Scroll Destination</p>
</body>
</html>
