If you don't need to support old browsers like IE6 and IE7 you can use:

window.onhashchange = function(){
  switch(location.hash) {
    case '#hash1':
      //do something
    break;
    case '#has2':
      //do something else
    break;
  }
}

But if you have to support older browsers you need to poll:

var oldHash = location.hash;
setInterval(function(){
  if(location.hash !== oldHash){
    oldHash = location.hash;
    //hash changed do something
  }
}, 120);
