history.replaceState (URL); useful when using AJAX

scripts.js

var pushSupport = $('html').hasClass('history') ? true : false; // does html have class .history? (modernizr.js required)

var toLoad = $('.element').attr('href'); // toLoad variable is .element's href attribute

if (pushSupport === true) { // if html does have class .history
    history.replaceState(null, null, toLoad); // replace URL with the new href
}
