Incrementally increasing number in URL - JavaScript

Question

I have a URL like http://blog.com/post/1 and I need a function which updates the number at the end of it, for pagination.

So far I have:

window.location(document.URL++);

Answer 1

var url  = window.location.href.split('/'),
    page = parseInt(url.pop(), 10);

// to go to next page, increment page number and join with URL

window.location.href = url.join('/') +'/'+ (++page);

FIDDLE
