> setInterval right? wouldnt it overload the browser?

Not necessarily, as long as your URL checking function is simple and
you don't check very frequently. Say, something like this:

var AnchorChecker = {
  initialize: function(){
    this.location = location.href;
    this.interval = setInterval(function(){
      if (this.location != location.href) this.anchorAltered();
    }.bind(this), 500); // check every half second
  anchorAltered: function(){
    // the url has been altered
