If you are talking about progressing to the next XHTML document, then it should be adequate to simply do
location.href="nextpage.xhtml";
If you are talking about moving within the same XHTML document, then the best you can do is to somehow identify the location within that page using an ID'd element, and jump to it:
location.href="#id";
There is no way that I am aware of to simply execute/simulate a page turn.
