Enables dragscroll on your website. It automatically detects when you want to select text, rather than scroll.

Please find a DEMO, here, together with more information on Utterscroll.

Requires jQuery, tested with jQuery 1.7.2.

Use like so: (for example)

<script src='jquery-scrollable.js'></script>
<script src='debiki-utterscroll.js'></script>

if (!Modernizr.touch)  // if not a smartphone
      scrollstoppers: '.CodeMirror, .ui-resizable-handle' });

Utterscroll is disabled inside the scrollstoppers. (It automatically understands to disable itself when you click buttons or select text, so you probably don't need to configure many special scrollstoppers.)

Please find in utterscroll-example.html a complete example HTML file, live here: http://rawgithub.com/debiki/utterscroll/master/utterscroll-example.html. Please have a look in that file — there are some things to think about: you currently need to load Utterscroll at the bottom of the HTML page, and you cannot use Utterscroll before the jQuery onload event has happened.

Nested Scrollbars Issue with Firefox

Utterscroll works in nested scrollbars, however, if the wrapping element doesn't have position: relative or absolute, the nested scrollbars seems to be broken in Firefox. Have a look at the demo (link above, to utterscroll-example.html) — in the demo, I've set position: relative on the wrapping element, so it should work in Firefox.


Utterscroll scrolls the closest scrollable element, or the window. However, scrolling anything but the window, depends on a jQuery selector, ':scrollable', being available. Otherwise, the window is always scrolled. So you should also include the file jquery.scrollable.js on your web page (it defines the ':scrollable' selector). That file is an excerpt from jquery-scrollintoview by Robert Koritnik.

As of 2012-05-23, tested with jQuery 1.7.2 and recent versions of Chrome, FF, IE and Opera.

As of 2012-02-29, tested with jQuery 1.6.4 and recent versions of Google Chrome, Firefox and Opera, and IE 6, 7, 8 and 9. (Scrolling the window has been tested; scrolling other elems has not been very thoroughly tested.)
