How can I detect the back/forwards buttons being clicked when using History.js?

Question

Im using History.js (click) with jQuery in my code.

When loading new content via ajax i use:

History.pushState({my:stateobject},"newtitle","supernewurl");

This seems to work since the URL is updated in the browser.

However, I don't get it where I can hook up my code whenever a back or forward button is pressed. Which method/event is used for this?

Answer 1

You need to bind an event handler to the statechange event, like this:

$(window).bind('statechange',function(){
// Do something, inspect History.getState() to decide what
})

There is a complete javascript snippet that comes with History.js, which can be used to 'ajaxify' a site completely: https://github.com/browserstate/ajaxify

Take a look there for more inspiration.

Answer 2

You wouldn't capture the back click event, as there is none.

What you want to do is make sure the history object is in the right state by using window.history.pushState, window.history.popState, window.history.replaceState methods.
