Is there a way to tell what direction the state is going with history.js?

Question

Like the title says, I'd like to be able to perform a different onstatechange event if the pushState function is called, instead of the back function. Or, if the go function is negative or positive.

Example:

if History.pushState() or History.go(1) are called, I want the statechange event's callback to be forwardPushState

if History.back() or History.go(-1) are called, I want the statechange event's callback to be backwardsPushState

Answer 1

A state is some data related to a page (as the user see it in the browser). If the user wants to be in a certain page, this page is the same, either he is coming from back button click or from forward button click.

PushState pushes a new state in the stack. It has no relationship with back and go. Back and go are functions to navigate over pushed states in stack. I say this because in your edit, it looks like you are thinking that pushState and go(1) are equivalent.

Maybe if you want to know from which direction the user is coming, you should analyse onstatechange event to know if it takes any parameter that stores direction, which is not a trivial task IMO.

The main thing I think, is that it has no relationship with the go (-1) or go(1) or back.
