I just discovered that there is a native HashChange event in the latest version of several browsers (FF, Webkit, IE) - this way navigation solutions working with the hash at the end of a URL work without nasty timers.
To add the event, simply use:
if ( window.addEventListener ) {
window.addEventListener( 'hashchange', function () { checkHashChange(location.hash) }, false );
} else if ( window.attachEvent ) {
window.attachEvent( 'onhashchange' , function () { checkHashChange(location.hash) } );
}
Take a look at these samples as well. In real world applications you still will need to use a combination of both methods (polling + events).
Concerning the support of the feature in various browsers, please click here for a comparison chart.
