I want to use the classic anchor link to have a top nav link towards the bottom of the page. Is there an AJAX alternative for this to make it look cleaner and better?
I believe you are confused between the terms Javascript and Ajax... I'm guessing you neeed an anchor link to smoothly animate or slide the scroller to the bottom/top of the page or to the anchor tag... check out this plugin here
Try the jQuery LocalScroll plugin. There's a nice demo to see all the ways to make scrolling nicer.
