How can I trigger on URL change in jQuery?

var current_href = location.href;
setInterval(function(){
    if(current_href !== location.href){
        // if changed Do ...
        current_href = location.href;
    }else{
        // Do ...
    }
},500);

This worked for me ^^

$(window).on('hashchange') // not firing

Try the hashchange event, which is built exactly for this - http://benalman.com/projects/jquery-hashchange-plugin/

That would be a hashchange event, so I'd suggest:

$(window).on('hashchange', function(e){
    // do something...
});
