Change a uri with javascript and not reload the page

I am trying to figure out how to change the URI with javascript and not reload the page. The action would be similar to navigating a folder structure on github where when you click a folder it takes you to a new url that is representative of the folder you clicked but t开发者_如何学Pythonhe page is not reloaded.

When I change my uri with js no matter what I seem to do the page refreshes. How can I avoid this?

Did you look at this answer? GitHub source dynamic navigation

But, take a look at this reference on using the browser's history object:
