Just append #[id of the div you want to scroll to]
to your page url. For example, if I wanted to scroll to the copyright section of this stackoverflow question, the URL would change from
http://stackoverflow.com/questions/9757625/jquery-how-to-scroll-to-certain-anchor-div-on-page-load
to
http://stackoverflow.com/questions/9757625/jquery-how-to-scroll-to-certain-anchor-div-on-page-load#copyright
notice the #copyright
at the end of the URL.
