Browser Back Button Behavior

BackButton

// I needed a way to hijack the browser back button on a Ruby on Rails app, 
// so users don't make a mistake thinking that they're editing a record instead of creating a new one
// Thanks to thecssninja.com site :)
(function(window, location) {
	history.replaceState(null, document.title, location.pathname+"#!/nobackbutton");
	history.pushState(null, document.title, location.pathname);

	window.addEventListener("popstate", function() {
	  alert('To go back or edit the record, please use the buttons below!');
	  if(location.hash === "#!/nobackbutton") {
		history.replaceState(null, document.title, location.pathname);
		setTimeout(function(){
		  location.replace();
		},0);
	  }
	}, false);
}(window, location));
