How can I remove the location hash without causing the page to scroll?

I believe if you just put in a dummy hash it won't scroll as there is no match to scroll to.

<a href="#A4J2S9F7">No jumping</a>

or

<a href="#_">No jumping</a>

"#" by itself is equivalent to "_top" thus causes a scroll to the top of the page

I use the following on a few sites, NO PAGE JUMPS!

Nice clean address bar for HTML5 friendly browsers, and just a # for older browsers.

$('#logo a').click(function(e){
    window.location.hash = ''; // for older browsers, leaves a # behind
    history.pushState('', document.title, window.location.pathname); // nice and clean
    e.preventDefault(); // no page reload
});
