Jquery history, inspect the history stack

Im using this history jquery plugin http://www.mikage.to/jquery/jquery_history.html and im trying to inspect the back stack.

I can call this $.historyCurrentHash to return the current hash, but im trying to figure out how to look one step back in the stack.

if i try calling this $.historyBackStack, but i just get an 'undefined'. anyone got any ideas?

I can see that its not a public variable, but im wondering if i need to mo开发者_运维技巧dify the library or just call it in a different way

Are you trying to look back at non-hash history? Like.. trying to see what the actual last different-URL-page was?

Because the browser does not expose this.
